R20 filter in natural gas line.

Series R20- Enameled Carbon Steel
Series R22- 304 Stainless

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.

  • Flow rates to 70,000 SCFM standard (higher capacities available upon request)
  • Section VIII Division I ASME code "U" stamp with National Board registration
  • Low Pressure Drop
  • Pleated media element design that maximizes useful filter area
  • Quick-opening swing bolt closures provide easy access
  • Fully customizable

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. 

Coalescing175Product1Filter 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.  (See product sheet for vessel quotation worksheet)

vaccuumProduct3Filter 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 wtih 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.  Please contact us for a solution to your challenging application.
