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.

M20 Back Pressure Pneumatic Booster (M20BP) Fairchild's M20BP is a smaller Back Pressure Pneumatic Booster designed for automation 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] (1000kPa) and handles up 250 psig, [17.0 BAR], (1700 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.

Model 4500 - 150 SCFM [255 m3/Hr] Forward/Exhaust High Flow No Bleed Volume Boosters (M4500A) Fairchild's Model 4500 Pneumatic Volume Booster is popular due to its rugged design and high flow capacity in an economical package. In its pilot operated regulator design, the M4500 handles up 250 psig, [17.0 BAR], (1700 kPa) supply pressure and has five available signal to output ratios to meet most control element requirements. The Fairchild Model 4500 Booster provides a flow capacity of 150 SCFM (255 m3/HR), which equates to a Cv factor of approximately 3.0 in both forward and exhaust modes.

M4500A Back Pressure Pneumatic Booster (M4500ABP) Fairchild’s M4500ABP is a High Flow Back Pressure Booster designed for automation 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] (1000kPa) and handles up 250 psig, [17.0 BAR], (1700 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.

Model 4800A - 500 SCFM [850 m3/HR] Forward/Exhaust High Flow No Bleed Volume Booster with Bypass Valve (M4800A) Fairchild’s M4800A is a High Flow Pneumatic Volume Booster specifically designed for Valve and valve actuation systems. With its Cv of 9 in both forward and exhaust modes, this pilot operated booster provides fast response and accurate control for valve actuation. In addition, the M4800A has an integral bypass valve, for optimum tuning and adjustment, even while in operation, to obtain maximum performance on opening and closing times with minimal overshoot or oscillation. In its pilot operated regulator design, the M4800A 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 4800A 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.

Model 4900A - 500 SCFM [850 m3/HR] Forward/Exhaust High Flow No Bleed Volume Booster (M4900A) 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 M4900A 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.

Model 200 - 1800 SCFM [3058 m3/Hr] Forward Ultra High Flow Volume Booster (M200) The Model 200 Pneumatic Volume Booster reproduces a pneumatic signal in a 1:1 ratio. It is ideally suited for systems that require input isolation or increased forward flow 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 Fairchild Model 200 handles up to 250 psig, [17.0 BAR], (1700 kPa) supply pressure and provides a flow Ultra high flow capacity of 1800 SCFM (3058 m3/HR), which equates to a Cv factor of approximately 18 in forward flow mode.
