Tap water entering the dwellings goes through a multi-stage purification procedure and at the outlet meets all the requirements for it. But when transported through pipes over long distances, it again becomes contaminated. We are not talking about germs - freshly added chlorine kills most of them.
The liquid is polluted, first of all, by the products of oxidation of the walls of the waterways, detached pieces of lime scale, as well as soil particles, if repairs were carried out along the route of the water or the tightness was broken by damage.
Coarse filters create a mechanical barrier in the way of components not provided for by the standards.
This simple feature improves water quality and serves to prevent damage to water folding units: faucet mixers, household appliances mechanisms(dishwashers and washing machines), facilitates further purification of drinking water.
All devices exclude the ingress of contaminants into the consumer watercourse. Differences in types provide choice to the buyer and greater compliance with volumes.
The most common and compact type of coarse cleaner, often referred to as a sump cleaner.
It consists of two nozzles - inlet and outlet - and a grid, in front of which there is a reservoir for collecting contaminants.
Stationary filter type for indoor use. It is a volumetric flask, with a replaceable cartridge through which water passes. Eliminates both large and small impurities.
Often used as an individual device for water that has undergone general house cleaning. The replacement element is made of plastic (disposable) or corrosion-resistant metal (reusable).
The design is attached to the wall, access to the cartridge is carried out using the key included in the kit.
High-speed pressure system for coarse cleaning: it is an impressive flask filled with a cleaning compound, inside which water is filtered. Pollution from 30 microns is retained.
The system is equipped with a device that regulates the composition of water. This type of filter must be connected to the sewer - pollution is removed through the drainage drain. Thus, the whole structure is a self-cleaning device.
The kit includes pressure gauges at the inlet and outlet, it is possible to regulate the pressure inside the system. Operation is possible only in a room with a positive temperature. Due to the size and cost, it is advisable to use at the entrance to the house.
When choosing a cleaning device, one should proceed from the purpose of each particular apparatus. The coarse filter for individual use has smaller volume indicators, and its installation and cleaning is easier. Devices for apartment buildings and industrial purposes are chosen by specialists.
When buying, you should check the device for visible damage and cracks - exclude factory and shipping defects.
Design flaws are a relative concept. Who is warned is armed. Therefore, in each case, before buying, you should read the instructions for using the model, make inquiries with the seller.
Disadvantages are revealed, unfortunately, only during operation, but this does not affect the quality of the filter, it only complicates maintenance and operation.
Before purchasing, you need to make sure that the configuration of the model fully complies with the declared list in the instruction manual. Warranties are required. When installing the filter yourself, do not use incomplete parts and tools if special fittings and keys are included in the purchase.
Installation is not difficult. Initial installation involves cutting the pipe and threading, so it is better to entrust this procedure to a plumber or representatives of accounting organizations: usually, when installing a water meter, specialists are required to install a coarse filter.
Further maintenance is carried out independently. You can unscrew the structure with a wrench, having previously turned off the water.
A coarse filter must be installed in the pipe section in front of the water consumption meter. This will ensure the correct operation of the device, protect all devices using water from damage.. The use of the device will ensure long-term operation of household appliances.
There is a fairly large selection of coarse cleaning devices on the market. The most popular individual models are mesh simple straight and oblique filters with removable revision cover. Developers, homeowners associations and management companies use large stationary devices. The cost of the first ones is from 120 rubles, and the professional ones fit into the range from 2,000 to 30,000 rubles.
Most residents of new buildings are relieved of the need to install an in-house device: when putting the house into operation, the presence of a water meter and a filter in front of it is checked. When using plastic pipes inside the house, the water is not polluted.
And in houses put into operation many years ago, the use of this type of cleaning is highly recommended: with many years of use of metal pipes, corrosive contamination is inevitable. Many reviews say this.
Olga, 26 years old
I have a small child, and I am very attentive to the composition of his diet. Before the coarse filter was installed, I was hesitant to use tap water to prepare mixtures. Even after fine cleaning and boiling, there was plaque and sediment. And the drinking water filter clogged very quickly. When they put the meter on the water, they also installed a coarse cleaning device - a small detail on the pipe. The water has become much cleaner.
Anton, 38 years old
In a country house, I have water from a well. Worn for analysis in the laboratory. Allowed to eat, but only after boiling - there are particles of soil. There are a lot of appliances in the house, from the dishwasher to the hot tub, and I realized that their longevity depends on the incoming water. The pressure from the source is good, so I installed a high speed pressure filter. Drainage led to the sewer, now there are no problems with cleaning - the system does everything by itself. Very satisfied.
Thus, the coarse filter is the imperative of the times. To save equipment, plumbing, plumbing equipment, its installation is necessary. Affordable price and high efficiency made these devices in demand among consumers.
Coarse filters (CSF) are such purification devices that purify the water entering the house from solid fractions - clay, lime, chlorine, rust, sand and other foreign components. CSF is traditionally installed in the water supply before entering the house, that is, before the meter and after the shut-off equipment.
The principle of operation of such devices is quite simple. The body of the product fixed on the water pipe contains a mesh element or cartridge. The flow of water following the water supply enters the filter.
Water is passed through a mesh or other medium capable of holding various solid particles. Purified water enters the system to the recipient and, if necessary, is subjected to fine purification.
Devices for rough water treatment differ from each other by the corresponding technical characteristics in the form of:
Although the principle of operation of various CSF models is the same, they still differ from each other in a number of ways. Such devices differ from each other in their shape, design, type of filter element, method of cleaning from filtered dirt.
1. Strainer- one of the most popular types. Known for long service life without changing the working element. The latter, as the name implies, is a metal mesh with cells ranging in size from 50 to 400 microns. The material is stainless steel. The designs differ from each other in the way they are inserted into the pipeline, in the methods of regular cleaning and maintenance.
The type of mesh filters can be divided into two more subspecies. These are recognized as:
Industrial or household mesh CSFs for cold water are supplied with a transparent case. This makes it possible to control the state of the grid.
Devices for hot water are made of metal, since this material is not afraid of high temperatures.
Most filter models also perform other functions. Thus, such a device can be equipped with a pressure regulating valve. The product can also be combined with a manometer. This can protect the inner surface of the pipeline and household appliances from pressure drops and water hammer. 
The installation of backwash devices is allowed in cases where a drainage tube is available, into which dirty water with impurities is sent after cleaning. Backflushing devices have become popular because of their small size and because they do not require manual cleaning.
Thus, the advantages of mesh filters include:
Of the shortcomings, the obvious ones are:
2. Flanged and coupling models differ in how they are connected to the water supply. With pipe diameters of two inches or more, coarse flanged models are more suitable. This applies to main water pipes or interchanges in the basements of high-rise buildings.
The connection of flanges on studs or bolts makes it possible to remove the device without dismantling other structural elements.
Devices on pipes are installed already at the design stage of the water supply network. 
Threaded filters are cut into pipes of small diameter. This design is used in domestic conditions, when supplying water to a private house. The filter, depending on its design, is either screwed onto the pipe directly or connected to it using quick-release union nuts (“American”).
CSF water of any models are installed subject to some general rules. For this:
All types of filters consist of inlet and outlet pipes, and a special tank (sump) that purifies water.
Depending on the location of this tank, the products are oblique and straight.
Settlers are closed with flange covers or screw plugs.
5. Water supply devices use cartridge or as they are also called, cartridge filters. This is a wall-mounted structure containing a transparent or opaque flask.
Replaceable cartridges are placed inside the flask, which are the main components for rough cleaning.
The material for replaceable elements is compressed polypropylene fiber or twisted thread, or polyester. They do not have the same filtering capacity, however, coarse mechanical cleaning is usually carried out with cartridges of 20-30 microns. 
Frequent replacement of cartridges seems to be a feature of using this type of device. Cartridges are used in systems where too small suspension particles are found that are difficult to capture by mesh devices.
The cartridge is designed specifically to retain small particles and debris. Cartridge structures are mounted in conditions of weak flows. For strong flows, such a device is already needed in a large size, which is more expensive.
Cartridges effectively remove mechanical particles and other impurities. With the help of a fibrous, carbon-treated cartridge, the water is purified from chlorine.
In addition, if you choose a stocking-type device, you can clean fibrous formations (algae, mud), viscous clay. An excess of such contaminants clogs the duct and leads to the breakdown of expensive products designed to remove molecular impurities.
Clogged elements cannot be cleaned by flushing. They need to be changed.
However, there are cartridges on the market that are a metal mesh. Such a cartridge can be cleaned when clogged.
It should be emphasized that such products are not without drawbacks. These include:
Such mechanisms should be installed and maintained in accordance with the following rules. For correct installation:
A couple of times during operation, you will have to resort to disassembling the device to clean and replace the mesh, or cartridge. More often this has to be done with "mud collectors" that do not have a flushing device.
Before you start disassembling the device, you should remove the pressure in the line by interrupting the water supply. The oblique filters are equipped with plugs with hexagon caps for a wrench. It is recommended to replace the paranitic pad with tow winding. This will increase the tightness of the connection and facilitate the further functionality of the device.
For vertically mounted straight filters, the flask can be removed with a wrench or a special curly wrench. Reassembly, if necessary, is carried out with the replacement of rubber or silicone sealed gaskets.
The dirt accumulated in the disassembled oblique filter is poured out of the tank into a container. The mesh is removed, the dirt is cleaned off and blown with a stream of compressed air. Damaged mesh should be replaced.
For straight type tanks, it is required to unscrew the flask and pour out the precipitate from it. The grid is also washed and blown, or a new replacement cartridge is installed.
It is much easier to maintain products with a flushing device. To do this, it is sometimes necessary to open the tap at the bottom of the flask, and flush the grid and the flask with a stream of water under pressure. Water is directed to the drainage pipe or a container is placed under it.
Even better, if a backwash device is mounted on the water supply. In this case, the water is directed in the opposite direction, as a result of which the mesh is cleaned much better.
Rough cleaning does not solve all the problems of obtaining high-quality drinking water. Therefore, the considered devices can be considered only as part of a general system for obtaining purified drinking water.

If a city apartment is connected to a common water supply system, then drinking liquid comes to a country house or cottage from a well or well. The purity of life-giving moisture is in question for both rural residents and city dwellers. From our article we will learn how to choose coarse water filters for an apartment and a country house. Let's get acquainted in detail with the types of cleaning devices and the rules for their operation.
Save
The liquid in an individual water supply is not always of high quality. The main reason for this statement is considered to be high pollution of the area far from megacities, especially considering that a huge amount of runoff is collected in groundwater.
Drinking liquid from a well is clean only at first glance, in fact, it can contain a huge amount of harmful substances. This can be checked by settling for 3-6 days. If during this time flakes form at the bottom of the vessel, then the water is dirty. Other qualities of life-giving moisture can be tested in the laboratory.
Analyzes and cultures can determine the following harmful substances:
Based on these analyzes and tests, a certain type of water pre-filter is selected. Here you need to consider the following characteristics of the liquid:
In a standard situation, after installing a coarse water filter, a multi-stage unit with a set of flasks is mounted. To destroy all pathogens, a special installation with ultraviolet irradiation is used. If you need to clean a small amount of liquid, you can purchase a filter jug with replaceable cartridges.
A multi-stage block purifies water well, but if small children live in an apartment or a private house, then at the end of all the filter elements, an element for forced mineralization is mounted, during which the user can get a liquid that is useful for the body.
Save
Some consumers use reverse osmosis for cleaning, but this is not necessary. Laboratory studies have shown that the specified element produces a dead, chemically inactive distillate at the exit. To obtain a normal high-quality liquid, reverse osmosis is connected to a forced mineralization device. In front of this block, an additional filter is mounted for fine and coarse cleaning, as well as a device for the destruction of pathogens.
Another disadvantage of reverse osmosis is low performance, so purchase models with a storage tank. Such a container will provide a small family with life-giving moisture.
The cost of a particular system includes:
Let's give a specific example for the Barrier and Aquaphor models. These devices cost about the same, but the cartridge of the last element passes a third less water before replacement. In this regard, the Barrier wins in terms of basic functions and performance. By this analogy, other filters are also selected.
Save
Depending on the design solution, several options for coarse water filters are used. Let's get acquainted with them in more detail.
The mesh filter is considered the cheapest and simplest. It is mounted on pipes with hot and cold water in an apartment or an individual water supply of a private house. There are mesh filters that are mounted directly on the faucet. This option is acceptable for use in the country. These devices are easy to install, if necessary, they can be reinstalled on a tap in the apartment.
Products have different diameters of cleaning holes. In addition, there are devices on the market with sumps that can be cleaned manually. Similar advanced models have a self-cleaning function. The mudguard can be oblique or straight. The last element is installed on horizontally directed pipes. At the same time, a hard water filter on a pipe with an oblique sump can be installed in any direction.
Save
In modern models, there are pressure regulators to maintain constant water pressure parameters. A useful filter mechanism is considered to be two pressure gauges that are mounted before and after the cleaning device. It is recommended to clean the system even with a small difference in the readings of the instruments.
The main advantage of such models is durability and reliability, resistance to temperature changes in the pipeline, as well as the low cost of the device. The disadvantage of the system is the retention of large particles and the need for constant cleaning of the sump, if the system does not have a self-cleaning function.
Such filter elements are equipped with special discs made of plastic. Each element has grooves that, when compressed, take dust particles and push the liquid. Such models allow to trap particles from 5 to 250 microns. Manufacturers paint products in different colors depending on the cell diameter. The advantages of the models are high strength indicators, good performance, the ability to use in a wide temperature range.
Save
Such filters for coarse water purification in an apartment are considered part of a complex system that is installed autonomously under the sink. The degree of liquid purification in these models is from 0.5 to 30 microns. They hold small debris well if the water is supplied under low pressure. With a strong supply of fluid flows, powerful devices will be needed.
The work of the filter consists in the retention of contaminants by special granules, which are located in the container under a certain gap. Dust-like particles settle on their surface during the passage of the water flow. The device consists of a plastic or metal case, which has high strength and resistance to temperature fluctuations. A filter element is installed in the middle of the device.
In many modern models, transparent plastic housings are installed, which makes it possible to control the level of cleaning and, if necessary, install a new polyester filter element or mesh insert. The last material can be removed from the device and washed. Polyester filter elements must be replaced.
Save
In such models, there are pressure regulators due to the fact that water is supplied to them under pressure. These are bulky devices with a high degree of purification. Depending on the diameter of the water supply, pressure filters are domestic or industrial. The degree of liquid purification depends on the cell diameter.
Save
Any of the listed filters is installed on the water supply after entering the apartment or private house. The device is located after the locking parts in front of the counter. The installation of the element is quite simple, a tow or other sealant is wound on its threads, then the threaded connections on the pipe are clamped to avoid leaks.
During installation, it is important to correctly position the device. The filter element can be oblique or perpendicular. Regardless of its position, the part is positioned so that the lid on the sump is located at the bottom. If this requirement is not met, dirt particles will settle on top, which will lead to malfunction or damage to the device.
Unlike a conventional coarse filter for hot water, cartridge devices allow you to remove not only large particles, but also other substances dissolved in the liquid. The device consists of a housing and a filter element, the filler here is considered to be coal or an adsorbent.
The procedure for installing the device is as follows:
At the final stage of work, turn on the water and check the device for leaks. If necessary, tighten the connecting elements.
Save
Many users face certain difficulties during the installation of a complex water treatment system under the sink. The filter is delivered already assembled, but it still needs to be connected to the water supply. The work consists of several simple operations:
Next, you need to open the water supply and check the tightness of all connections. Do not wait for the liquid to quickly appear from the tap, the filtration process must first go through. Wait until clean water appears and only then close the valve.
Save
The installation process of such a system is almost no different from the previous version. First, they turn off the water, install the tap and install the tee. The difference between reverse osmosis and other types of filters is the need for a drain device for contaminated liquid. After passing the molecules through the filter element on the other side, a dirty solution is obtained, which must be discharged into the sewer. For this, a special pipe is used.
SaveOver time, various dust-like particles accumulate in the filter element. To clean the device from contamination, it is necessary to unscrew the sump and rinse the mesh under water pressure. If this element is worn out, it is replaced with a new one. Some filters have a self-cleaning system. Here it is enough to unscrew a special tap and flush the dirty water into the sewer.
In the absence of this mechanism, the garbage is removed manually. To do this, shut off the liquid in the main line, unscrew the sump and clean the grid from contamination. Such events should be held at least once every three months.
Water delivered to a dwelling by means of a water pipe contains a certain percentage of impurities in the form of sand, scale fragments, corrosion, lime particles, etc. In order to protect people and household appliances, it is imperative to install a filter on a coarse and sometimes fine water pipe (the second option is used to eliminate odors, organic and chemical contaminants, individual microorganisms).
For all devices that carry out mechanical filtration of water, a structural similarity is characteristic. The housing is equipped with an internal metal mesh or other filtering device. These can be special discs for cutting off coarse sand, corrosion, etc. An important part of the design of such a filter is a branch that collects delayed debris.
When the sump is completely filled, the water must be turned off, and the drain cleaned and rinsed. The frequency of such cleanings is directly affected by the degree of water pollution. In order to prevent this procedure should be carried out at least 4 times a year.
Regardless of the specific model, all mechanical filters work on a similar principle. At the same time, a number of design features may differ: we are talking, first of all, about the type of filter, its configuration, installation method and the method of removing dirt that has accumulated in the nozzle.
The mesh filter has a cleaning element in the form of a metal mesh, for the manufacture of which stainless steel is used. Such a grid has cell sizes in the range of 50-400 microns. When mounting the filter on a water pipe, you need to ensure that the inspection cover looks down. Installation in the pipeline system is carried out using conventional tools included in the standard plumbing kit. When making threaded connections, it is important to achieve their complete tightness in order to avoid water leaks.
The popularity of the mesh filter is due to its good service life, without the need to replace the filter element. This is what they compare favorably with another coarse filter model - cartridge (cartridge). These devices are mainly wall-mounted, due to the large bulb included in their design. The flask itself can be transparent or opaque: inside it is equipped with a replaceable cartridge, for the manufacture of which polyester, twisted polypropylene thread, or pressed fibers are used. When installing the filter, a plumbing sealant is used, which will help to avoid leaks in the future.
The cleaning abilities of such cartridges may vary: coarse mechanical water filtration is carried out by products of 20-30 microns. The contaminated filter element must be replaced with a new one: it is forbidden to wash and reuse the used cartridge. When installing water filters on pipes in an apartment, most often cartridge models are combined with mesh ones, which significantly increases the effect of mechanical water filtration. In this case, it is better if the strainer is in front of the bulb filter, because. this prolongs the life of the latter.
Any type of mechanical filter is characterized by the presence of two nozzles - inlet and outlet, as well as a special sump where water is cleaned. According to how exactly this sump is located, mesh filters are divided into straight and oblique. In the first case, the sedimentation tanks are located at a certain inclination to the water flow, which is very convenient in situations where the pipeline passes above the floor itself. In addition, vertical pipeline sections are equipped with such models.
In the second case, the sump has a perpendicular arrangement with respect to the water supply. The direct filter for the pipeline is of considerable size, which implies a lot of space for its installation under water communications. The large size of the sump allows vertical filters to achieve a good level of cleaning. To close it, there is a convenient threaded plug, or a flange cover.
Depending on the type of tie-in, with which filters for pipes for water purification are mounted in the plumbing system, they are flanged or coupling. Flanged products are usually equipped with pipes with a cross section of more than two inches. First of all, we are talking about main water pipelines and interchanges located in the basements of high-rise residential buildings.
Bolts or studs make it possible, if necessary, to quickly dismantle such a filter: while all other parts of the water supply remain in place. Sections of highways that are equipped with flange filters are outlined at the stage of drawing up project documentation. As for pipes with a diameter of up to two inches, they are equipped with threaded filters. In such a situation, quick-release union nuts (the so-called "American" nuts) are used as connecting elements.
Another type of classification of mesh filters is according to the method of extracting accumulated debris from the sump. Mud collectors are called models in which the possibility of flushing is not provided. This mainly applies to all oblique strainers, as well as some models of the direct type of nozzle location. To carry out cleaning from accumulated dirt, disassembly and washing of the device is carried out. On direct filters of a perpendicular arrangement of the sump, where there is a flushing system, an outlet valve is also installed: through it, the settled area is drained into the sewer system and the outlet is cleaned with a water stream.
With the help of rough mechanical cleaning, most of the debris is removed from the water, but some chemical elements and their compounds still remain.
In this case, fine cleaning equipment is used, the main of which can be the following filter elements:
You should know that this filter for water pipes is mainly equipped with replaceable working elements. Each manufacturer indicates the frequency of replacements on the attached instructions: this is affected by the period of operation of the device, and the amount of treated volume of water.
In systems with several stages, after mechanical filtration, the water flow is passed through ultrafine filters, which are located in several groups, one after another. As a result, the output is high-quality drinking water. At the first stage, mechanical debris is removed from it: the water becomes almost transparent, but this is only the beginning of the purification process.
The second stage is equipped with an ion-exchange cartridge, which allows you to change the chemical composition of water, removing from it all elements and substances harmful to health. As a result, traditional scale formation is not observed during boiling. In the third stage, the water is purified with pressed activated carbon: in this way, conditioning of the water stream is achieved.
After that, the water becomes tasty, and begins to smell pleasant. It is also given a crystal transparency: now it can be safely used for drinking and cooking. As a rule, the place for installing three-flask systems is the space under the kitchen sink. This approach allows not to disturb the overall appearance of the interior. To bring the purified water outside, the sink is equipped with an additional tap.
Reverse osmosis systems are not in vain called the highest quality water filters: in the process of such purification, the molecular level is affected. In this case, a thin-film membrane of a semi-permeable type is used for filtration, where the pores have a size of no more than 0.0001 microns.
This makes it possible to eliminate almost all impurities (99%). Microscopic membrane pores allow only water molecules to seep through. Before reverse osmosis, water is passed through several purification stages in order to prevent rapid clogging of reverse osmosis filters with large debris.
Most often, these systems contain the following degrees of purification:
Reverse osmosis filtration removes harmful chemicals and metals from water. In addition, in this way, water can be purified from many harmful microorganisms, as a result of which it becomes crystal clear and safe.
The disadvantage of this method is that it removes both harmful impurities and useful minerals and salts from the composition of water. To solve this problem, some manufacturers of reverse osmosis systems began to include mineralizers and ionizers in the design. If the pressure in the water supply is less than 3 atmospheres, reverse osmosis filters are equipped with special pumps: they help create the optimal functional pressure in the system.
When choosing the optimal method for water purification, it is important to determine which goal should be achieved. It is hardly reasonable to treat the entire volume of water entering the dwelling to the level of drinking water. To extract large particles from it, mesh filters or filter flasks are sufficient. Usually they put a hard water filter on the cold water and hot water pipe. The resulting water can be used for taking water procedures, washing, washing the floor. The kitchen can additionally be equipped with a multi-stage fine cleaning system, with or without reverse osmosis.
Most often, such a filter is mounted under the kitchen sink, on the surface of which an additional tap is displayed (if you want to cook food, water is taken from it, if not, from ordinary taps located nearby). In addition, fine filters are able to protect plumbing and household appliances from excessively hard water.
Coarse water filters for an apartment (FGOV) trap relatively large insoluble elements, for example:
Therefore, it is necessary to install the FGOV in the apartment.
Their work is based on the mechanical retention of large particles. The devices differ in:
Consider the types in more detail:
Devices that work with cold water have a transparent body. So you can monitor the conditions of the grid.
Devices operating with hot water, metal. After all, metal copes with high temperatures.
Many models have other functions as well. For example, they may incorporate a valve to adjust the pressure. They can be combined with a manometer. This is a safety measure for the internal space of the pipeline and household models from pressure surges.
It is logical to install devices with automatic flushing where there is a drainage pipe and dirty water with impurities follows it.
Advantages of mesh models:
There are also disadvantages, but conditional:
All FGOVs have similar installation criteria:
They have different cleansing potential. But the coarse cleaning parameter is 20-30 microns.
These devices can often change cartridges. The devices themselves are usually placed where there are small garbage components that do not capture mesh models well.
The cartridge traps such particles. And the charcoal-treated fiber cartridge can remove chlorine from the water.
The installation of these models takes place where weak flows are noted. In conditions of strong flows, a large device is used.
Note! There is no auto-flush in the cartridges. They have to be changed.
This activity must adhere to the following criteria:
If you use the filter several times, you will need to disassemble it to clean or replace the screen or cartridge.
Before disassembling the device, it is necessary to relieve the pressure in the network. This stops the water supply.
In oblique models there are corks with convenient lids, which have six faces. This is made specifically for the wrench. The paranitic gasket is removed. A tow winding is put. This makes the connections tighter. And in the future, the functionality of the device is improved.
The flask of straight filters with a vertical position can be removed with a wrench. The flask is put back with new gaskets.
You can remove dirt from an oblique model like this: the model is disassembled, the dirt merges. The mesh is retrieved. Pollution is removed. This area is dried with compressed air. The damaged mesh is changed.
In direct modification, the flask is unscrewed. There is sediment coming out of it. The mesh is flushed. Drying. Or put in a new cartridge.
It is easier to work with models with autowash. The tap at the bottom of the flask opens periodically. The mesh and flask are cleaned. Pressurized water is used. Then the water goes into the drain or into a substituted container.
For more convenient work, an automatic flushing device is installed on the water supply itself. Then the water follows the flow in the opposite direction. And the cleaning of the grid is more efficient.
There are many FGO models on the market today. The following is a TOP-5 of the most common devices.
To your attention a good selection of filters for any type and budget.
The kit includes:
