ASME Code Filters with integral stainless steel safety cages are individually constructed from code certified materials. Filter elements in these units remove solid contamination from air and gas streams, ensuring trouble free operation of downstream process equipment.

Rugged Enameled Steel or 304SS Construction

These air and gas pipe line filters offer exceptional protection for compressed gas pipelines, air dryers, pneumatic controls, and other pipeline equipment. They are fabricated from rugged enameled carbon steel (series P40) or 304SS (series P42), 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.

Standard Connection Sizes from 1" to 12"

Male NPT (MT) or raised face flanges (RF) in-line connections are std. Alternative orientations and sizes are available upon request. A simple blind flange closure assembly is standard on all models.

Recoverable Sewn or Rubber End Filter Elements

Classic radial fin textile media elements are unsurpassed for low ∆P, dirt holding capacity and efficiency. They stop particulates before they can move downstream. Select either recov- erable 10μ Sewn End Filter Elements or 10μ long life low cost urethane rubber molded end elements, as your needs dictate to remove 98% of all airborne dust and dirt. Unlike PVC, our urethane rubber ends have no phthalate elastomers or other plasticizers. Dozens of alternative filter media are available for services having finer micron retentions, elevated temperatures and/or aggressive chemistry.


Models P40-0202-MT-020 and larger include CS leg supports. (add 18" to OH)  Carbon steel support legs in any length, gauges, special finishes, and head lift assemblies are optional on any model. Call for information on vessels having other pressure services, 304SS, or other materials of construction.
