Fairchild’s M4900A is a High Flow Pneumatic Volume Booster designed for high precision applications. With its Cv of 9 in both forward and exhaust modes, this pilot operated booster provides fast response, very low deadband and high precision control. In its pilot operated regulator design, the Fairchild Model 4900A High Flow Pneumatic Volume Booster handles up 250 psig, [17.0 BAR], (1700 kPa) supply pressure and delivers an output pressure up to 150 psig [10.0 BAR] (1000kPa). The Fairchild Model 4900A Booster provides a flow capacity of 500 SCFM (850 m3/HR), which equates to a Cv factor of approximately 9 in both forward and exhaust modes.
