Gas Filters F, FG, FGP
Construction and Function
Gas filters of the types F, FG and FGP with cellulose elements are made from steel and welded. Observation of all pertinent pressurevessel regulations and directives required by UDT and ASME is ensured during planning and static calculations. The cross-section shows how the filter works.
The contaminated gas enters the body of the filter through the inlet. The design of the filter ensures the heaviest solid contaminants are precipitated first. They sink to the bottom when the velocity of the gas has been reduced and then accumulate in the lowest part of the filter. The remaining contaminants accumulate on the surface of the filter insert. The permeabilities of the filters are designed so that the velocity of the gas in the insert does not exceed 2 m/s. At the inlet and outlet, 25 m/s should not be exceeded. The recommended max. velocity is 20 m/s.
