FilterFab – Dry Particulate Filters

FilterFab F-Series Filters Remove Dry Particulates from Gas Lines

FilterFab Logo

All gas lines have dry contaminants (such as pipe scale, dirt, and rust) that will damage or even destroy your downstream equipment. Using a Filterfab F-Series Dry Filter will remove all forms of dry contamination, lengthening the life of your equipment and saving thousands of dollars in maintenance costs.

F-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 180 and 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.
Filter Lid Choices
  • 4 pressures (MAOP). Available in 180, 285, 740 and 1480 psi.
  • 7 standard line sizes. Choose from 2″ to 12″. Custom sizes to 24″ available.
  • A wide range of flowrates. 5,000 to 25,000,000 scfh. See chart below for capcities for each filter size.
  • 2 types of filter cartridges. Our standard replaceable filter cartridge uses polyester-felted media or polyester/cellulose media, both of which remove 99.9% of all solid particles 10-microns and larger. This is well beyond the recommendations of all major manufacturers of meters and regulators. Our standard filter size is 10 microns, but filters with retention ratings as low as 0.3 micron to as high as 75 microns are available.

FILTERS ALWAYS PAY FOR THEMSELVES

Build a FilterFab F-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 example below:

We Love Special Designs!

Are there any special design changes we can make to the standard unit you have chosen to help you fit into a tight space, remove a particularly stubborn contaminant, resist a high temperature, or simply make your job easier? FilterFab started in business in 1983 by building special designs, so you can count on us to find a solution to your unique problem.

F2M “Miniature” Filter

Our Model F2M “Miniature” filter was designed to be used in lower-flow applications where a strainer is just too coarse but your budget does not allow for our standard size F2 housing. Shown here with a full-size F2 the F2M is available with flanged inlet/outlet or either female or male pipe connections. This housing is an excellent choice for tight spaces and small meter runs in any mounting orientation. We can also provide smaller threaded connections on this filter (down to 1″) if you so desire.

ASME Information

Housings are designed and built to ASME Boiler & Pressure Vessel Code, Section VIII, Division 1 specifications by Section IX certified welders but not U-Code stamped without an extra charge.
