The high performance micro regulator has a slightly larger footprint than the Model 70 and, combined with the Model 70, its encapsulated needle valve provides a highly responsive and stable operation. The Model 72's aluminum bonnet and body make it a lightweight and versatile product. With a control sensitivity of 2" water column and a supply pressure impact of less than 0.5%, the Fairchild 72 pneumatic regulator provides accurate and reliable accuracy to maintain your desired set point regardless of supply pressure changes or conditions. The Model 72 pressure regulator will handle large supply pressures of 250 psi, 17 BAR, and provide five (5) set point pressure ranges from 0-5 psi, 0-3.5 BAR, 0-35 kPa to 2-100 psi, 0.1-7 bar, and 15-700 kPa.
