Product Overview
The Fisher 67CFR-237 Instrument Air Filter Pressure Regulator is designed to provide clean, stable, and accurately regulated air pressure to pneumatic control valves, valve positioners, and industrial process instrumentation. Manufactured by Fisher, an Emerson brand, this direct-operated pressure-reducing regulator maintains a controlled downstream pressure despite normal variations in upstream instrument air supply. Its adjustable outlet pressure range of 0–60 psi (0–4.1 bar) supports reliable pneumatic equipment operation, improved control accuracy, and consistent performance in industrial automation systems.
Part of the Fisher 67C Series, the 67CFR-237 combines pressure regulation, an integrated 5-micron polyethylene filter, an internal relief valve, and a pressure gauge within a compact aluminium housing. Its filtration system helps remove solid contaminants from incoming instrument air, while the internal relief mechanism provides limited protection against minor downstream overpressure caused by seat leakage. The regulator features 1/4-inch NPT connections and can be mounted on compatible valve actuator and positioner assemblies using appropriate mounting hardware. It is suitable for oil and gas processing, chemical manufacturing, power generation, water treatment, and industrial pneumatic control applications.

How do I find the right part for my system?
Three options. Search by part number if you have the OEM code from Parker, Danfoss, Linde, Kawasaki, Kayaba or Grundfos — our search recognises both manufacturer codes and aftermarket cross-references. Browse by category if you know the component type (pumps, valves, cylinders, etc.). Or send a spec sheet to our engineering desk and we'll cross-reference against our 3,000+ SKU catalogue within one business day.
Can you help me size a pump or valve for my application?
Yes — sizing support is included with every order. Send us your operating pressure, flow rate, viscosity, drive speed and duty cycle, and our engineers will recommend a suitable component from our catalogue with full datasheets. We don't custom-build parts ourselves, but we can spec the right OEM component for almost any standard industrial application.
Can you cross-reference a discontinued part?
Yes — cross-referencing is one of the things we do most. Send us the original part number (even if the manufacturer has dropped it) and our engineering desk will identify a current equivalent or compatible alternative. Cross-reference lookups are free and typically come back within 4 business hours.
