Energy saving tip No 17 (Compressed air system pressure)

Tip summary

Reduce air compressor discharge pressure to the lowest acceptable setting. (Reduction of 1 kg/cm2 air pressure (8 kg/cm2 to 7 kg/cm2) would result in 9% input power savings. This will also reduce compressed air leakage rates by 10%)

Proposed actions

    • Conduct a regular check for the difference between the compressor pressure setting and the air system requirements.
    • Decrease the compressor pressure to the accepted minimum pressure.
    • If the difference still very high check you system for leaks and pressure losses reasons.
    • Plan to conduct the required changes to decrease system pressure resistance in the nearest chance.


    • Low cost opportunity with a high ROI.


    • Estimated energy savings range: 3-5 % of the overall compressor energy use.
    • Decrease equivalent amount of CO2 emissions accordingly to save the environment.


    • Checking and adjusting air compressor pressure to the optimum pressure can save more than 3% of pumping system energy use.
    • Please share this tip with others to share knowledge and increase energy efficiency awareness.
