Gas filters FG

Gas filters FGSteel gas filter FG is designed to refine natural gas (GOST 5542), other non-aggressive gases and air from mechanical impurities in the gas supply systems.
Climatic version is UZ GOST 15150 (operating in moderate climate indoors with natural ventilation, temperature from -40 to +45°C). Filters are made of the following nominal inside diameters - DN50, DN80, DN100, DN150, DN200. There are welded and flanged nipples.

Also it is possible to fill the filter with pressure differential indicator or differential pressure gauge letting to control the degree of gauze element pollution.
Within overall modernization of production changes and improvements also concerned gas filters FG with the nominal inside diameter up to 200 mm. The main feature is in use of removable filter cassettes consisting of reinforced steel mesh and gauze element.

Gas filters FGThe original design of the gauze element is in its corrugated surface considerably increasing the filtration area as well as in use as a filter material a synthetic non-woven sheet with different densities and filtration degree up to 25 microns. This allows to catch the smallest contaminants passing through the pipeline.
The usage of a brand new gauze element allows to decrease face-to-face and overall dimensions by more than two times and to increase the carrying capacity up to 100.000 m3/h.

Filtering degree is 80, 50, 25 microns. Easy maintenance and replacement of the gauze element.

(*the version without supporting structure is possible)
