FilterFab C-Series Filters Remove Liquid Droplets,
Liquid Slugs and Dry Particles from Natural Gas Lines

Many gas lines have oil and water in mist or droplet form that, along with solid contaminants such as pipe scale, dirt, and rust, will damage or even destroy your downstream equipment. Use a Filterfab C-Series Coalescing Filter, and you will remove all forms of moisture and dry contamination, lengthening the life of your equipment and saving thousands of dollars in maintenance costs.

C-Series Dry Filters have:

  • 4 different closure styles. FilterFab has designed its lid closures to make filter element changeout as easy and as fast as possible. 2" thru 6" line sizes in 285 psi ratings use a quick-opening swing-bolt lid or blind flange, while larger and higher pressure filters incorporate a blind flange with lifting lug or a lifting davit. Optional threaded high-pressure closures are also available.
  • 3 pressures (MAOP). Available in 285, 740 and 1480 psi.
  • 7 common line sizes. Choose from 2" to 12". Custom sizes to 24" available.
  • A wide range of flowrates. 18,000 to 17,000,000 scfh.
  • Proprietary Coalescing Filter Cartridge. FilterFab's C-Series coalescing filters use a proprietary reverse-flow, radially-finned, high surface area filter cartridge unlike those used by any of our competitors. These cartridges are built with layers of borosilicate fiberglass sandwiched into layers of felted polyester media to remove 99.9% of all liquid droplets, fogs, and mists, plus all particulate matter down to 0.3-microns in size.

  • Build a FilterFab C-Series Part Number

    To choose the correct FilterFab model for your application, start by building a part number. You will need to know line size and pressure rating. See this example:

    C-Series Build Chart
  • Now check the model number you have determined above against the flowchart below to make sure that your choice will handle the flowrate of your application.

    These flowrates are based on 1-1/2 psi pressure drop up to 150 psi; 3 psi for higher line pressures.
