  • Product Description
  • Dimension Drawing
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. With its pilot operated regulator design, the M20 handles up to 150 psig [10 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 [76.5m3/Hr], which equates to a Cv factor of approximately 1.0 in forward mode.
  • Provides 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
  • Easy installation in the field
  • Allows servicing the Model 20 using Service Kit without removal from line
  • Suitable for use in all Canadian territories and provinces
NOTES: Oil free air must be applied to the regulator. Use a filter to remove dirt and entrained liquid in the air line ahead of the regulator. If an air line lubricator is used, it MUST be located downstream of the regulator, to avoid interference with regulator performance.
