Part Number: M20

Model 20 Pneumatic Precision 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 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.


  • 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


  • Fast responsive operation
  • Easily suits your downstream pressure requirements
  • Allows tuning for optimum dynamic response (1:1 ratio only) and cycle free operation with valve positioners
  • Facilitates use with pneumatic signal devices that cannot be adjusted to zero signal pressure
  • Eliminates hunting and buzzing
  • Allows servicing without removal
  • Easy installation in the field
  • Suitable for use in all Canadian territories and provinces
