FilterFab Manufacturing Corporation is a leading manufacturer of dry natural gas filters and coalescing filter separators. FilterFab offers a broad line of gas filters and separators which are produced in its manufacturing facility in Aliquippa, PA.

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.
