These air and gas pipeline filters offer exceptional protection from particulate contamination for compressed gas pipelines, air dryers, pneumatic controls, and other pipeline equipment. They are fabricated from rugged carbon steel (series P20) or 304SS (series P22). Each filter vessel is designed, constructed, and stamped in accordance with ASME Boiler and Pressure Vessel Code requirements for unfired pressure vessels. Any model can be readily modified at your request to more exactly fit your needs.

A hinged swing bolt closure is standard on models P20-0200 and larger. These closures allow quick, easy access to the filter element, which reduces maintenance time and cost.

NPT or CL-150 raised face flange (RFSO) connections are standard. Alternative orientations, sizes, or connections types are available upon request. Models P20-0202-RF-030 and larger include 18″ carbon steel legs. While our standard line of filter vessels provides a starting point, our core business is designing vessels specifically to fit the customer’s application. Changes may include special finishes, additional testing requirements, adding/moving connections, providing ancillary equipment, or dealing with space limitations. Please send us your specifications and application details so we can make the best possible recommendation.

Classic radial fin textile media elements are unsurpassed for low ΔP, dirt holding capacity, and efficiency. They stop particulates before they can move downstream. Select either recoverable sewn end filter elements or our long life, low cost polyurethane rubber molded end elements. Standard efficiency is 10 µm, but we have dozens of alternative filter media options from 750 µm down to 0.1 µm. Custom elements are available for services having elevated temperatures, aggressive chemistry, or other special considerations. Please contact us for a solution to your challenging application.
