Main-line filters

ENG
 
 

Filters of this type are installed on the water-supply main-line of a house, bungalow, cottage, or flat. Therefore, they are termed main-line cartridge filters. The most widely used filters of this type are those with mechanical clearing cartridges.

 


  • Main-line filters are a simple and reliable way to protect household appliances and plumbing equipment from plugging, corrosion which destroys metallic pipelines and fittings, and rust deposition.
  • In main-line filters, it is possible to use special-purpose cartridges for protection from definite kinds of impurities: removal of excess iron (BA cartridge), water softening (BS cartridge), removal of chlorine, and conditioning (cartridges with activated charcoal).
  • For protecting laundry machines and boilers, the Geyser Company produces special main-line filters with polyphosphate charge, Geyser 1 PF. If you have installed this filter, it is no longer necessary to introduce special additives in laundering: Full scale protection of the laundry machine parts will be assured.

Choosing a model

There are usually two main-lines in flats, those for hot and cold water. Therefore, a separate main-line filter is required for each type of water. Because hot-water filters operate under more severe conditions, more stringent requirements are imposed on them, and their cost is higher.
The productive capacity of main-line filters is determined by their size and by the mesh size of the filtering element. The hydraulic loss in the filter can range from 0.1 to 0.5 bar. It is particularly important to take this fact into account if the main-line pressure is low.


There are a lot of materials for main-line filter cartridges: grids, foamed or woven polypropylene, corrugated materials, windings. It is important to remember that cartridges intended for cold water are unsuitable for hot water, but cartridges intended for hot water are also suitable for cold water. Therefore, in main-line filters for cold and hot water in a flat you can use a single type of replaceable cartridge.
The majority of cartridges are disposable and are not subject to regeneration after the end of the service life. The world-only reusable cartridge for fine mechanical clearing of hot and cold water, Aragon 3, is produced by the Geyser Company.


The casing diameter corresponds to two standards: Big Blue (BB) and Slim Line (SL).
For the Big Blue (BB) standard, the diameter is 185 mm.
For the Slim Line (SL) standard, the diameter is smaller, 130–140 mm.
The majority of the filters used have a height of 10 or 20 inches.
The choice between these alternatives should be made taking into account the expected water consumption by the family: The larger the number of taps and water-consumption sites, the larger the size of the filter required. The SL standard is advisable for small water consumption, and the BB standard, for medium and large water consumption.


Filter design

Main-line filters consist of a dismountable flask made of a plastic or of stainless steel, with a replaceable filtering element, cartridge, arranged in the flask.

 

The size and type of the casing and cartridge are chosen on the basis of the required productive capacity, operation conditions (cold or hot water), and degree of clearing (filtration threshold from 1 to 20 μm). The most widely used are cartridges with the filtration threshold of 5 μm. The replaceable parts strictly correspond to standards of filter casings.


Filter installation

The filters are fitted in the water-supply main-line. For convenience in use, the system can include a by-pass and a cut-off ball valve.


When choosing the place for installation of the main-line filter, it is important to remember that at certain periods the cartridge should be replaced by unscrewing the flask. Therefore, the filter should be installed in an accessible place, with a free space below it of no less than 2/3 of the flask height.



Cartridge replacement

Cut off the water supply to the filter. Using a wrench supplied with the filter, unscrew the flask, remove the spent cartridge, and replace it by a new cartridge. Be attentive, because a certain amount of water remains in the filter flask. Assemble the filter.


Geyser Typhoon

Universal main-line filter Geyser Typhoon for hot and cold water. Purifies cold water in a flat to the potable water quality by removing hardness salts, iron and heavy metal ions, petroleum products, chlorine, foreign odor, and also rust particles and other mechanical impurities.
