Use your discharge pressure and desired flow rate to estimate required air pressure, resultant air usage, and cycle rate.
Draw a horizontal line at your discharge pressure.
(e.g. 30 psi / 2 Bar)
Draw a vertical line at your desired flow rate.
(e.g. 90 lpm / 5.4 m3/hr / 23.8 gpm)
At line intersect, estimate required air pressure.
(e.g. 70 psi / 4.8 Bar)
At line intersect, estimate resultant air consumption.
(e.g. 28 SCFM)
At line intersect, estimate resultant cycle rate (e.g. 190 CPM).
