Model 4500ABP Pneumatic Back Pressure Booster
Brand: Fairchild Industrial ProductsRotork Fairchild’s M4500ABP is a High Flow Back Pressure 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 M4500ABP 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 4500ABP Back Pressure Booster provides a flow capacity of 150 SCFM (255 m3/HR), which equates to a Cv factor of approximately 3.0.
