Model 80D Compact Multi-Stage Precision Pressure Regulator
Brand: Fairchild Industrial ProductsThe Rotork Fairchild Model 80 is a compact two stage precision pressure regulator designed for applications that require high performance, low droop and accurate process control in a smaller footprint, where space may be limited or you wish to reduce the overall size of your panel or equipment.
This compact, high quality pneumatic regulator combines the flow capacity of a process regulator with the precision of an instrument regulator.
The Model 80 features control sensitivity of less than 0.1" water column, very low consumption and high accuracy to deliver consistent and reliable precision accuracy to maintain your desired set point regardless of supply pressure changes or conditions.
The Fairchild Model 80 precision regulator will handle a 250 psi, 17 BAR maximum supply pressure and offers three (3) output pressure ranges from 0-20 psi, 0-1.5 BAR, 0-150 kPa up to 1-100 psi, 0.05-7 BAR, 7-700 kPa.
