FAIRCHILD MODEL 4500A - PNEUMATIC VOLUME BOOSTER

Model Number: 4500A

The Fairchild Model 4500A Pneumatic Volume Booster reproduces a pneumatic signal in a 1:1 ratio in multiplying or dividing ratios. Control sensitivity of 1" water column allows use in precision applications.

Maximum Output Pressure: 150 PSIG Maximum
Supply Pressure: 250 PSIG
Flow Capacity: 150 SCFM @ 100 PSIG supply SCFM, 20 PSIG set point
Ratio: 1:1 to 3:1
Pipe size: 3/8 NPT - 3/4 NPT

Key benefits and features:

  • Five signal to output ratios meet most control element requirements.
  • Control sensitivity of 1" water column allows use in precision applications.
  • Large Supply and Exhaust Valves provide high forward and exhaust flows.
  • Soft Supply and Exhaust Valve seats minimise air consumption.
  • A balanced Supply Valve minimises the effect of supply pressure variation.
  • An Aspirator Tube compensates downstream pressure droop under flow conditions.
  • A separate Control Chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing.
  • Optional remote feedback port minimises pressure drop at final control element under flow conditions.
  • The optional adjustable By-pass Valve lets you tune for optimum dynamic response. (1:1 ratio only)
  • Unit construction lets you service the Model 4500A without removing it from the line
