Series R20/R22 Coalescing Filter to 175 psig

Brand: Shawndra Products, Inc
Rugged Carbon Steel or 304SS Construction

These air and gas coalescing pipeline filters offer exceptional protection from liquid and particulate contamination for all types of compressed gas pipelines, air dryer systems, pneumatic controls, and other pipeline equipment.

They are fabricated from rugged carbon steel (series R20) or 304SS (series R22). 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.

Quick-Opening Closures

A hinged swing bolt closure is standard on models R20-0200 and larger. These closures allow quick, easy access to the filter element, which reduces maintenance times and cost.

Filter Housing (Vessel) Options

In-line NPT or CL-150 raised face flange (RFSO) connections are standard. Alternative orientations, sizes, or connection types are available upon request.

Models R20-0202-RF-30 and larger include 18" support 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 NDE/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.

Filter Element Options

Our vertically oriented (inside to outside flow) pleated media coalescing filter elements are unsurpassed for effective removal of fine entrained oil, water, hydrocarbon condensate, and other aqueous mist droplets from air/gas flows.

Standard media is composed of borosilicate microfiber glass, which offers the highest level of coalescence at the lowest pressure drop.

Standard efficiency is 0.3 µm, but we do offer alternative medias with high efficiency options, achieving aerosol retentions down to 99.99% of 0.1 µm and larger (based on independent test lab data).

Custom elements are available for services having elevated temperatures, aggressive chemistry, or other special considerations.
Features
  • Intake air flows to 40,000 SCFM Std.
  • ASME U Stamp Std., Nat'I. Board registered
  • Exceptionally low ΔP, high flow
  • Pleated element design - exceptional useful filter area
  • Hinged swing bolt closure, easy access, O ring seat
  • 304SS throat safety cages and ΔP taps std.
