High Pressure Compressed Gas Filter

FOR ALTERNATIVE FUELING STATIONS

Our model UHPC-SL Filter Series is specially designed for high pressure compressed gas coalescing filtration. These housings are rated for 5,700 PSIG and manufactured to ASME B31.3 Specifications. The UHPC-SL Series is machined of carbon steel and completely coated with nickel/chrome plating for rust protection. The assemblies provide high efficiency filtration with a choice of three grades of robust coalescing filter cartridges which remove large quantities of liquids and solids, and being 90%+ void volume, give very long service life. A 1.25” reservoir area allows collection of large volumes of liquid before draining.

Our coalescing microfiber elements have integral inner and outer Stainless Steel cages, with metal end caps for added strength, and a captured O-ring for a positive seal (element is pictured below). The standard element seals are Buna-N. The housing seals are matched to the element seals. When ordering a non-standard seal for the housing, be sure to add the appropriate suffix to end of element part number; V = Viton, E = EPDM, KZ = Kalrez (i.e. SL38-172-70CSX3-V). Five-Layer Stainless Steel elements are also available in a variety of microns, for bulk contaminates.

Applications

  • High Pressure CNG Fuel Dispenser Service Filter
  • Alternative Fuel Station Filter
  • Booster Compressor Service Filter
  • Storage Gas Filter

Liquid aerosols, primarily lube oil carryover are common in high pressure compression systems. Our reinforced microfiber coalescing elements are an ideal solution since the glass fiber is excellent at capturing submicron aerosols. The inner and outer stainless steel support cores along with the spring at the base of the cartridge provide protection from dynamic pressure swings.

The SL series of spring loaded elements are constructed with inner and outer stainless steel cages to provide higher differential ratings. We recommend using our CS grade (all glass fiber) coalescing spring loaded elements for continuous removal of liquids without the loss of efficiency in natural gas service. For extreme applications we recommend our line of “RC” Reinforced Coalescing Cartridges. These cartridges consist of borosilicate glass inner layer sandwiched between two, rayon/phenolic layers. The reinforced inner/outer layers provide excellent strength.
