Compact high-pressure filtration for gas and liquid equipment protection
The Welker F-9 Filter is a compact high-pressure particulate filter designed to remove solids from gas or liquid products before they reach downstream equipment. Installed on pumps or in small-volume high-pressure applications, the F-9 separates particulates through stainless steel filter media to help protect components, reduce contamination, and support reliable operation. With stainless steel construction, multiple filter element options, compact design, and pressure capability up to 4000 psig, the F-9 provides dependable gas and liquid filtration for sampling, conditioning, injection, and process equipment.
