Universal Silencer Series FASH Absolute Filter Silencer
For use on Centrifugal Compressors, Blowers and Gas Turbines.

Universal FASH Series Absolute Filter Silencer represents the ultimate in high efficiency air filtration for industrial application. The unit employs first and second stage elements having a combined depth of 20", to provide unsurpassed efficiency on ultra-fine particulates and a very large surface area for low flow resistance and extra large dirt retention capacity. Filtration efficiency is 99.9+ % on particles 0.3 microns and larger in size. A unique feature on this line is a fluid seal means of sealing the final filter rather than the conventional gasket seal. A tongue projection from the filter holding frame is im­mersed in a stable silicon jell fluid contained in a channel on the downstream side of the P-12F final filter, affecting a 100% by-pass free system. Staging the filters permits changeout of the less expensive pre-filter "roughing" pad and primary filter more frequently than the final filter for economy. Under typical conditions, the pre-filter will re­quire replacment about once per year while the final filter may provide 2-3 years service (Filter specifications and service instructions for the P-8 pre-filter and P-12F final filter are given on page 9). The FASH features an integral silencing section for a moderate degree of noise attenua­tion. The unit is constructed of heavy duty steel sheet and plate, welded throughout, making it arugged, long-lasting trouble-free air filtering component. All models are equipped with removable weatherhoods, pressure tap and flanges drilled to match 125/150# ANSI specifications. Inside and outside surfaces are primed and given a finish coat of enamel paint. Suitable mounting legs may be fitted in the field or will be quoted upon application.

Dimensions In Inches, Weights In Lbs.
  1. Nominal capacity is based on exit velocity of approximately 5000 ft. /min. (Filter element capacity maybe greater but this is unrelated to actual unit capacity, which is primarily a function of outlet size.) For specific sizing and pressure drop data.
  2. Weights include filter elements.
