  • Subminiature Pressure Regulator (M70)

    The Fairchild Model 70 precision pressure regulator controls a pressure signal for pneumatic instrumentation applications. This miniature regulator is ideally suited for applications with limited space. In addition, its brass bonnet and valve body makes the M70 an excellent choice for use in sensitive applications. The Model 70 pneumatic regulator also has an integral vibration damper to provide low noise operation. The Fairchild Model 70 features control sensitivity of 2.5" water column and a supply pressure effect of less than 1% to deliver consistent and reliable precision accuracy to maintain your desired set point regardless of supply pressure changes or conditions. The Model 70 brass pressure regulator will handle a 250 psi, 17 BAR maximum supply pressure and offers five (5) set point pressure ranges from 0-5 psi, 0-3.5 BAR, 0-35 kPa up to 2-100 psi, 0.1-7 BAR, 15-700 kPa. 70220, 70230, 70240, 70250

  • High Performance Miniature Pressure Regulator (M72)

    The Fairchild Model 72 high performance miniature regulator has a slightly larger footprint than the Model 70, which in conjunction with its over molded pintle valve, provides highly responsive, yet extremely stable operation. The Aluminum bonnet and valve body of the Model 72 makes it a light weight and versatile product. The Fairchild Model 72 pneumatic regulator features control sensitivity of 2" water column and a supply pressure effect of less than 0.5% to deliver consistent and reliable precision accuracy to maintain your desired set point regardless of supply pressure changes or conditions. The Model 72 pressure regulator will handle a 250 psi, 17 BAR maximum supply pressure and offers five (5) set point pressure ranges from 0-5 psi, 0-3.5 BAR, 0-35 kPa up to 2-100 psi, 0.1-7 BAR, 15-700 kPa.

  • Miniature Pressure Regulator (M55)

    The Fairchild Model 55 is a compact precision polymer pressure regulator for high performance applications where space or weight may be limited or material compatibility concerns dictate use of a polymer construction regulator. Stability of regulated pressure is maintained under varying flow conditions through the use of an aspirator tube which adjusts the supply valve in accordance with the flow velocity. The Model 55 pneumatic regulator features control sensitivity of 5" water column to deliver consistent and reliable precision accuracy to maintain your desired set point regardless of supply pressure changes or conditions. The Fairchild Model 50 pressure regulator will handle a 150 psi, 10 BAR maximum supply pressure and offers four (4) set point pressure ranges from 0-10 psi, 0-0.7 BAR, 0-70 kPa up to 2-100 psi, 0.1-7 BAR, 15-700 kPa.
