To find Outlet Pressure (MPa/bar/psi) at a specific
delivery (liter/min or gpm) and operating air pressure
(MPa/bar/psi):
1. Locate desired delivery along bottom of chart.
2. Read vertical line up to intersection with
selected fluid outlet pressure curve.
Curve slopes from left to right.
Follow left to scale and read outlet pressure.
A 1.25 MPa, 12.5 bar (180 psi) air pressure
B 0.7 MPa, 7 bar (100 psi) air pressure
C 0.49 MPa, 4.9 bar (70 psi) air pressure
D 0.28 MPa, 2.8 bar (40 psi) air pressure
