Model 66 Pneumatic Stainless Steel Regulator
Brand: Fairchild Industrial ProductsThe Rotork Fairchild Model 66 is a stainless steel pressure regulator for high performance applications with corrosive environments and/or high temperatures.
The Model 66 Stainless steel housing and internals, along with its fluorocarbon elastomers are compatible with a wide range of corrosive materials and difficult operating environments.
The Fairchild Model 66 pneumatic regulator features control sensitivity of 1" water column to deliver consistent and reliable precision accuracy to maintain your desired set point regardless of system pressure changes or conditions.
The Fairchild Model 66 pressure regulator will handle a 500 psi, 35 BAR maximum supply pressure and offers five (5) set point pressure ranges from 0-10 psi, 0-0.7 BAR, 0-70 kPa up to 2-150 psi, 0.15-10 BAR, 15-1,000 kPa.
Features- Stainless Steel and Fluorocarbon
- Control sensitivity to 1" water column
