Pneumatic Volume Booster Model 4500A

Fairchild's Model 4500A Pneumatic Volume Boosters are popular due to their rugged design and high flow capacity in an economical package. In its pilot operated regulator design, the Model 4500A handles up 17 Barg [250 psig] supply pressure and has five available signal to output ratios to meet most control element requirements. This booster provides a flow capacity of 255 m3/HR, which equates to a Cv factor of approximately 3.0 in both forward and exhaust modes.

Features

  • Flow capacity of 255 m3/HR.
  • Five signal to output ratios.
  • Control sensitivity of 2,5 mbar water column.
  • Soft Supply and Exhaust Valve seats.
  • Separate Control Chamber.
  • Optional remote feedback port.
  • Optional Adjustable By-Pass Needle Valve (includes bubble tight exhaust valve).
