 | Introduction |
The compressed air technology overview (PDF) introduces the main energy saving opportunities for businesses and demonstrates how simple actions save energy, cut costs and increase profit margins. For more practical compressed air energy-saving tips see the Switch to saving DVD.
Our top 3 recommended carbon saving compressed air measures:
1. Reduce the pressure
Compressed air is often generated at the compressor’s maximum pressure (often 7 bar, 100 psi). Reducing pressure by 10% can lead to 5% savings in energy. Make small, incremental reductions, checking that operations are not affected.
2. Test for and fix leaks
Even a tiny leak (just 3mm) could cost you more than £700 a year in wasted energy, so carry out a ‘no-load’ test to check for leaks. We explain how in this short video:
If you do have leaks, locate them by listening for them out of hours. Or hire ultrasonic leak detection equipment. Ultrasonic equipment (shown in the video) is the most convenient way of checking for leaks, but may require specialist operation.

3. Check that compressed air is really required
Compressed air is expensive to run, and yet cheaper options exist for certain jobs. Educate your staff not to allow compressed air to vent to atmosphere (e.g. cleaning benches). A usage policy that suggests safe and easy alternatives to compressed air (as well as detailing acceptable uses for it) will help your staff save energy and reduce carbon.
