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
operating 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.
