Product Description

The Rotork Fairchild Model 70 subminiature 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 has an integral vibration damper to provide low noise operation. The Fairchild Model 70 features control sensitivity of 2.5 in water column and a supply pressure effect of less than 1 percent 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).
  • Allows installation in restrictive spaces
  • Permits use in corrosive or difficult environments
  • Provides low noise operation
  • Facilitates highly accurate setpoint control
  • Repeatability within 0.06 psig dead ended
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.
