The above figures are based on values from the Compressed Air & Gas Handbook. Calculations assume a conservative cost of $0.25/1000 cu. ft. of compressed air, 100% coefficient of flow, and working 8,760 hours/year, at 100 psig.

Air Loss Cost

Artificial Demand:

• Most air systems operate at artificially high pressures to compensate for flow fluctuations and downstream pressure drops.

• At higher pressures, air users consume more air than needed to perform a specific task.
