Natural Gas FIlters (Aluminum Constructed)

Protect your natural gas equipment and sensitive instruments from water, oil, and dirt with our high efficiency 100% machined aluminum filter assemblies. The robust housing construction, along with the high efficiency microfiber element is a proven solution for the demands of the natural gas industry.  We are able to remove liquid and particulate down to 0.01 microns, while exhibiting a low initial pressure drop with our vacuum formed filter elements.

The miniature 315A coalescing series is ideal for point -of -use applications as a last chance filter, whereas the 360A / 370A  coalescing series have increased  liquid holding capacity which makes them suitable  for remote service.  Both series use our captured O-ring design and threaded element retainer for positive sealing on the housing, and element which makes service quick and easy.

Features

  • Rugged, 100% Machined Anodized Aluminum Construction
  • Remove 99.99% Of Oil, Water, & Solids From Natural Gas
  • Up To 1500 PSIG Maximum Rating

Applications

  • Prevent Freeze Outs
  • Fuel Gas Filters
  • Protect Metering Valves
  • Natural Gas Compression Filters

At the heart of our filter products is the filter element. Choosing the correct element insures proper results for your specific application:

Disposable Microfiber Elements

Disposable Microfiber Elements are most commonly used since they offer exceptional filtration, high flows with minimal pressure drops, and excellent chemical compatibility. These are ideal for use in sample conditioning, instrumentation, CNG, and Emission/Environmental service.

  • We recommend using the 70C grade element with natural gas service since the element’s fiber matrix offers a low initial pressure drop, quick drainage, high flow rates, while still providing excellent filtration efficiency to protect your system. We have many alternatives available for your specific requirements. Feel free to contact us at 1-800-311-5561 or email sales@unitedfiltration.com.

Vapor Adsorption Cartridges

Our vapor adsorption cartridges are packed with either carbon/charcoal for oil vapor adsorption (designated as CC) or Silica Gel for water vapor adsorption (designated as SG).

  • These units are only for adsorption of oil or water vapor and should be preceded by at least one coalescing filter assembly (70C).
  • Up To 1500 PSIG Maximum Rating
  • Alternative Fuel Filter
  • Protect Natural Gas Regulators
  • Pilot Valve Protection
