If you’re working with natural gas systems, industrial combustion equipment, or pneumatic instrumentation, having a reliable pressure control solution is critical. The Fisher 67CFR-239/SB filter regulator (new model: 67C-1663-38548) is a proven choice for engineers and procurement teams worldwide.
What is the Fisher 67CFR-239/SB?
The Fisher 67CFR-239/SB is a compact, integrated filter and pressure regulator designed specifically for instrument air and gas applications. It combines two essential functions — filtration and pressure regulation — into a single, space-efficient unit that protects downstream equipment while maintaining precise pressure control.
Why the Model Number Changed to 67C-1663-38548
Emerson periodically updates Fisher product nomenclature to streamline global inventory and improve traceability. The 67CFR-239/SB is now designated as 67C-1663-38548, with identical performance specifications and dimensional interchangeability.
Technical Specifications
• Connection: 1/4″ NPT female threaded
• Outlet Pressure Range: 0-125 PSI adjustable
• Maximum Inlet Pressure: 250 PSI
• Factory Set Point: 50 PSI
• Media Compatibility: Natural gas, manufactured gas, LPG, compressed air
Key Applications
This filter regulator is commonly found in:
- Natural gas transmission and distribution infrastructure
- Gas turbine power generation plants
- Industrial burner management systems
- Petrochemical processing facilities
- City gate stations and pressure reduction stations
Benefits of the 67CFR Series Design
The integrated design eliminates the need for separate filter and regulator installations, reducing footprint and potential leak points. The robust construction handles harsh industrial environments, while the accessible filter element simplifies routine maintenance.
