The Welker FIR-1 Filter / Instrument Regulator is designed to filter and provide regulation of an instrument pneumatic supply. It is intended for use as part of instrument packages.

The regulator of the FIR-1 is non-relieving. Welker recommends that a relief valve, such as the Welker RV-1 or RV-3 series relief valves, be installed downstream of the FIR-1.
