Fisher 67D Series Direct-operated Regulators and Filter Regulators 67DS 67DF 67DFR 67DFRS Fisher Pressure Reducing Regulators

The tiny stainless box that feeds clean air to every analyzer shelters and purge panels forever

Analyzer shelters, gas chromatographs, moisture analyzers – they all need clean, steady instrument-quality air at 20–40 psi. The 67D is the one that just works. All stainless internals, direct-operated (no pilot), tiny 1/4" ports, and it holds the set pressure rock-solid for years. No filter to change, no dripwell to empty, just bolt it on and forget it. Most plants have dozens of them running since the 1980s and they still hold 35 psi like the day they were installed.

• Four outlet pressure springs – 0–125 psi range
• Panel mount or pipe mount – whatever you have room for
