Performance Charts
Fluid Outlet Pressure
To find fluid outlet pressure (MPa/bar/psi) at a specific flow
(lpm/gpm) and operating pressure (A/B/C):
1. Locate desired flow at bottom of chart.
2. Follow vertical line up to intersection with selected operat-
ing pressure curve (solid line). Follow left to scale to read
fluid outlet pressure.
Air Consumption
To find air consumption (l/min. or gpm) at a specific fluid flow
(l/min. or gpm) and operating pressure (A/B/C):
1. Locate desired flow along bottom of chart.
2. Read vertical line up to intersection with selected air con-
sumption curve (dashed line). Follow left to scale to read
air consumption.
