Series F20 - Enameled Steel w/Bolted Closure
Series F22 - 304 Stainless Steel w/Bolted Closure
Series F20 & F22 w/bolt seal closure closed circuit air & gas filters are essentially similar to series E in-line filters except their outlet connection is directly out the bottom. Where practical, this orientation reduces ΔP by eliminating an elbow. They are also slightly less expensive than equivalent E series housings. *Filter elements w/304SS screen &/or center cores are also available if required.
Connection Sizes from 1/2" to 24"
Male NPT (MT) or flat face flanges (FF) are std. Flanges match diameter & drilling for 150# ANSI standard. Specify optional female NPT (FT), bevel (BE) or plain cut (PE) stub necks where you wish to weld in place. Increased or decreased connections are also available on any model.
Choice of Filter Elements
Series F22 In-Line Air & Gas Filters are similar to enameled steel series F20 but are constructed instead from 304 stainless steel. Filter elements w/304 SS media support screen &/or center cores are also available if desired. (Replace the "K" in the filter element part number with an "N" for 304SS core and 304SS media support screen, or a "Q" for 304SS core with epoxy coated aluminum media support screen). These textile media elements are superior for low ΔP, high dirt holding capacity and exceptional efficiency. They stop pipe scale and other contaminates before they can travel downstream. Select from 10µ, 4µ High Efficiency, or 0.3µ coalescing filter elements as your needs dictates to remove 98% of all dust, dirt, and if coalescing, fine mists. Addt'l. media and element styles are available for services at elevated temperatures or specific chemistries. View more of the air and gas filter vessels in our inventory

Coalescing Services
When used for coalescing services, housings should be installed with flow reversed from that illustrated. Inlet flow should travel first to the inside of the filter element, passing through the media to the outside. Coalesced liquids will also pass through the element to collect in sump area below.
