- Manufacturer’s declaration
* Depending on the position of the indicator’s visual scale regarding the direction of the gas flow through the filter or pipeline, the arrow type contamination indicators are manufactured in two versions:
- LEFT-TO-RIGHT;
- RIGHT-TO-LEFT.
Example of the identification code for the gas filter with the arrow type contamination indicator (left-to-right version), connection size 2 inches, max operating pressure 6 bar, coupling connection, housing material – aluminum, climatic version –30...+60 °С:
FН2–6С, –30...+60 °С (left-to-right version of the indicator)
Information to be specified additionally:
- For filters DN 15...50 the housing version is indicated: coupling or flanged connections;
- For filters DN 15...200 in steel housing, the housing material is indicated additionally: steel;
- For filters DN 150, DN 200 in cast iron housing, the housing material is inficated additionally: cast iron;
- As standard the filtering element (cartridge) is made from porous polymer material.
Upon customer’s individual request it is possible to manufacture the filter with mesh filtering element (cartridge), made from metal wire mesh. Special design of the filter allows removing filtering element (cartridge), if necessary, for its cleaning or replacement.
- Ambient operating temperature:
–40...+90 °С (for filters with polymer filtering element (cartridge));
–60...+120 °С (for filters with mesh filtering element (cartridge));
- Mounting position: onto horizontal and vertical pipelines.
- Degree of filtration:
- for polymer filtering cartridge (polyethylene): 2 microns, 5 microns, 10 microns, 20 microns, 50 microns (standard);
- for strainer filtering cartridge (metal mesh): 20 microns, 80 microns, 200 microns.
