Application
The F42 Air Intake Filter Silencer is recommended for use on the intakes of centrifugal
compressors, fans, blowers, engines and turbines where dust-free process air
requirements are highly critical and there is a need for additional silencing of the air
intake system. When used on the inlets of compressors, engines and blowers, an
appropriate silencer must be installed between the air moving device and the filter.
Design
The F42 Series employs a three-stage filtering system which consists of a Type F3
primary, a Type F4 intermediate and a Type F5 filter. The rigid housing is designed to
accept 24˝ x 24˝ filter elements, wherein the final filter contains a fluid seal to prevent
bypass. The internal design provides a safeguard to prevent small size foreign objects
from entering the air intake passageway when filters are removed. To effectively reduce
intake noise, a silencing device is designed into the filter housing air outlet nozzle. This
silencer is designed so there is no increase in the housing pressure drop. The minimum
efficiency of the final filter is not less than 99.97% (by DOP test method) on 0.3 microns
and above. Field tests indicate final filters need to be changed once every 18 to 24
months if the primary and intermediate filters are properly serviced. Special designs are
available upon request.
Construction
Welded sheet and plate steel construction. Metal joints are sealed to prevent dirt and air
from bypassing the filter element. All surfaces are prime coated, followed with a final coat
of machinery enamel. Flanges are drilled to match 125 lb. American Standard Flanges.
Weatherhoods are included. Special finishes, or materials, are available at extra cost.
