Brand: Fairchild Industrial Products

The Rotork Fairchild Model 20BP is a smaller Back Pressure Pneumatic Booster designed for automated or remote controlling of the back pressure or relief operation typically found in tank systems and other pressurized systems. 

In its pilot operated design, the M20BP will operate from a signal pressure of up to 150 psig [10.0 BAR] (1,000 kPa) and handles up 250 psig (17.0 BAR, 1,700 kPa) system pressure.

The Fairchild Model 20BP Back Pressure Booster provides a flow capacity of 45 SCFM (76.5 m3/Hr), which equates to a Cv factor of approximately 1.0.
