The Fairchild 66BP Stainless Steel Regulator is designed for corrosive environments and high temperatures. The large Control Diaphragm area allows for increased sensitivity.

Flow Capacity: 22 SCFM (37.4 m3/HR)
Output Pressure Range: Up to 150 psig (1000 kPa)
System Pressure: 150 psig (1000 kPa)

The Fairchild 70B controls a pressure signal for pneumatic instrumentation. This regulator is ideally suited for applications with limited space.

Flow Capacity: 2.5 SCFM (4.25 m3/HR)
Output Pressure Range: Up to 100 psig (700 kPa)
Supply Pressure: 250 psig (1700 kPa)

The Fairchild 72 controls a pressure signal for pneumatic instrumentation. This regulator is ideally suited for applications with limited space.

Flow Capacity:2.5 SCFM (4.25 m³/hr) @ 100 psig [7 BAR] supply and 30 psig [2 BAR] setpoint
Exhaust Capacity: 0.15 SCFM (0.29 m³/hr) with 5 psig [0.35 BAR] downstream pressure
Supply Pressure: up to 300 psi [20 BAR], (2000 kPa) Max supply; 25 psig [1.8 BAR], (1800 kPa) Min supply.

The Fairchild 80D is a precision two-stage device that incorporate a force balance design with pilot control. This compact, high quality unity combines the flow capacity of a process regulator with the precision of an instrument regulator.

Flow Capacity: 14 SCFM (23.8 m3/HR)
Output Pressure Range: Up to 100psig (700 kPa)
Supply Pressure: 150 psig (1000 kPa) for 20 psig (150 kPa) range, 250 psig (1700 kPa) for 60 - 100 psig (400 - 700 kPa) ranges.

The Fairchild 81 is a precision two-stage regulator that combines a pilot control system with a basic force balance system to provide accurate output pressure regulation. It is recommended for use in both highly sensitive instrumentation and control circuits and in equipment requiring high flow with precise control.

Flow Capacity: 50 SCFM (85 m3/HR)
Output Pressure Range: Up to 100 psig (700 kPa)
Supply Pressure: 100 psig (700 kPa) for 2 and 5 psig (14 and 35 kPa) ranges, 150 psig (1000 kPa) for 20 - 100 psig (400 - 700 kPa) ranges.
