Overview
The Fairchild 63252NKG is a Model 63 pneumatic filter service regulator manufactured by Fairchild Industrial Products. This compact unit combines pressure regulation, internal filtration (5-micron), and a 2-inch dial pressure gauge in one integrated assembly. The knob-adjustment design (K option) with gauge (G option) makes it ideal for technicians who need quick, intuitive pressure tuning and real-time readout in manufacturing, automation, and pneumatic control applications.
Key Features
- Adjustment range of 2–120 PSIG (0.14–8.3 bar) for precise pressure control
- Integrated 2-inch pressure gauge for real-time monitoring
- Knob adjustment mechanism (1-15/16 in. O.D.) for smooth, ergonomic operation
- Internal 5-micron filter cartridge (TT-AFR) for contamination protection
- 1/4″ FPT (female pipe thread) line and gauge ports for compact installation
- Nitrile seals for broad fluid compatibility
- 300 PSIG (20 bar) maximum inlet pressure rating
- 25 SCFM (42.5 m³/hr) flow capacity at 100 PSI supply and 20 PSI setpoint
