It is a non-bleed, high-flow precision pressure regulator designed for applications requiring high performance, low consumption, and precise process control. With control sensitivity of less than 0.5" water column, low consumption and high flow rate, the Model 4000A pneumatic regulator provides accurate and reliable accuracy, maintaining the desired set point regardless of changes in supply pressure or conditions. The Fairchild 4000A pressure regulator will handle a maximum supply pressure of 250 psi, 17 BAR, and provide five (5) output pressure ranges. From 0.5-10 psi, 0.03-0.7 BAR, 3-70 kPa to 5-250 psi, 0.35-17 bar, 35-1700 kPa. The 4000A has a flow rate of up to 150 SCFM, 255 m3/hr.
