The Model 4000A from Fairchild has been designed for processes that need high performance, accurate control and very low consumption. It does not have the bleed function and has a 0.5 inch water column control sensitivity, high flow capacity and low consumption. This regulator has been made to maintain the set pressure precisely, accurately and reliably regardless of any change in the input pressure or any other conditions. This pump can handle a maximum supply pressure of 17 bar or 250 psi with 5 pressure ranges for the output between 0.5 and 10 psi, 0.03 and 0.7 bar 3 and 70 kPa all the way to 5 to 250 psi, 0.35 to 17 bar, and 35 to 1700kPa. This high flow no bleed pressure regulator has a flow capacity reaching 150 SCFM and 255 cubic meters per hour.
