Fairchild Model 30 - Precision Pressure Regulator

The Fairchild Model 30 is designed for applications that require high capacity and accurate process control in a small package. A poppet valve which is balanced by utilising a convoluted diaphragm, ensures a constant output pressure even during wide supply pressure variations. Stability of regulated pressure is maintained under varying flow conditions through the use of an aspirator tube which adjusts the air supply in accordance with the flow velocity. The Model 30 Regulator uses the force balance principle to control the movement of the valve assembly which in turn controls the output pressure.

Features include:

• Control sensitivity of 1/4” water column variation is low use in precision applications
• Compensating diaphragm lets the regulator remain unaffected by supply pressure changes
• Flow of up to 40 SCFM with 100 psig supply allows use in applications with high flow requirements
• An aspirator tube compensates downstream pressure droop under flow conditions
• Aseparate Control Chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing
• Unit construction lets you service the Model 30 without removing it from the line
• Canadian Registration Number (CRN) Certification for all territories and provinces
