Model 20 Pneumatic Precision Volume Booster

Brand: Fairchild Industrial Products
The Rotork Fairchild 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], (1,000 kPa) supply pressure and has ten available ratios to cover a wide range of applications. The M20 Booster provides a flow capacity of 45 SCFM (76.5 m3/HR), which equates to a Cv factor of approximately 1.0 in forward mode.

Typical Part Numbers are 20812, 20822, 20832, 20842, 20852, 20862, 20813, 20823, 20833, 20843, 20853, 20863
Features
  • Flow capacity of 45 SCFM (76.5 m3/HR)
  • Ten available pressure ratios
  • Optional Adjustable By-Pass Needle Valve option includes bubble tight exhaust valve
  • Optional Fixed Negative Bias
  • A separate Control Chamber isolates the diaphragm from the main flow
  • Unit construction
  • Mounting Bracket available
  • Canadian Registration Number (CRN) Certification
