Model 11 Pneumatic Pressure Regulator

Brand: Fairchild Industrial Products

The Rotork Fairchild Model 11 is a Low Pressure Precision Pressure Regulator designed for applications that require high performance and accurate process control at very low pressures down to 3 inches water column.

The Fairchild Model 11 pneumatic low pressure regulator features control sensitivity of less than 0.05" water column and high flow capacity to deliver consistent and reliable precision accuracy to maintain your desired set point regardless of supply pressure changes or conditions. 

The Fairchild Model 11 high precision pressure regulator will handle a 150 psi, 10 BAR maximum supply pressure and offers five (5) output pressure ranges from 0-0.5 psi, 0-0.034 BAR, 0-3.4 kPa up to 0-12 psi, 0-0.83 BAR, 0-83 kPa.

The Model 11 has a flow capacity of 27 SCFM, 40.7 m3/hr.
Features
  • Sensitivity of 0.05" WC for Precision Control in low pressure applications 
  • Relief Valve provides high exhaust flows
  • Optional Low Bleed seat minimizes air consumption
