F-19

Compact filter drying for small pneumatic instrument supply lines.

The Welker F-19 Filter Dryer is a compact natural gas and instrument air filter designed to clean and dry supply gas before it reaches small pneumatic instruments, solenoid valves, pneumatic controllers, and actuated equipment. As gas flows through the F-19, filter media removes water, aerosols, odorant, mercaptan, sulfur, and liquid hydrocarbons to help protect downstream equipment. With a spin-on filter body, mounting bracket, and clean dry supply gas performance, the F-19 supports reliable instrumentation operation in high-pressure natural gas and instrument air applications.
