Model 20 Volume Booster
he Fairchild Model 20 Pneumatic Precision Booster for High Flow and Exhaust Capacities is a device that uses a force balance system to control the movement of the supply and exhaust valves. At set point, the force due to signal pressure that acts on the top of the Upper Diaphragm balances with the force due to output pressure acting on the bottom of the Lower Diaphragm. 150 psig maximum output pressure, 250 maximum supply pressure, 45 SCFM flow capacity, 11 SCFM exhaust capacity, 1/4" water column sensitivity, 1.0 ratio accuracy, aluminum body and housing, zinc plated steel and brass trim, and Nitrile on Dacron Fabric diaphragm.

Model 20BP Back Pressure Volume Booster
The Model 20 Volume Booster is a smaller pneumatic device capable of high flow and exhaust capacity. This device uses a force balance system to control the movement of the supply and exhaust valves. As a pilot operated regulator design, the M20 handles up to 150 psig, [10.0 BAR], (1000 kPa) supply pressure and has ten available ratios to cover a wide range of applications. The Fairchild Model 20 Booster provides a flow capacity of 45 SCFM (76.5 m3/HR), which equates to a Cv factor of approximately 1.0 in both forward and exhaust modes.
