Topic planner: Compressed Air

 

This topic helps you….. “heighten awareness of the correct use of compressed air”

Here the message should be about getting staff to understand the importance of using compressed air properly.

You should focus on compressed air energy saving for a defined period of time. Use the posters and fliers to inform staff on how to use compressed air efficiently. Use the compressed training module to get people to understand the potential energy waste from compressed air and how to reduce it.

Continue throughout the period by reinforcing the message with these members of staff through a variety of communication methods.

It is likely that office-based or other “white-collar” staff will not really be interested in compressed air, so you will need to target your effort at the staff who use and control compressed air.

Did you know?

  • Compressed air generation is one of the most expensive utilities in an industrial facility.
  • The average production site leaks 20 - 30% of the compressed air generated.[Source: SEI Energy Agreements Programme 2007 Compressed Air Technical Guide]
  • One 4mm hole in a compressed air distribution pipe can cost €2,005 p.a. on a typical 8 bar compressed air system. [Source: SEAI Energy Agreements Programme 2007 Compressed Air Technical Guide]
  • For every 100 units of electrical energy that go into a compressor only 10 units of compressed air energy are produced.[source: SEAI CA presentation from training module]
  • A compressor left idling can consume up to 40% of its full load power.[source: SEAI presentation]
  • It costs about 10 times more in energy to run a tool on compressed air than it does to run it on electricity.
  • It costs over 5 times more to run a compressed air system over its lifetime than to purchase it in the first place. [Source: Compressed Air Case Studies. Good Practice Case Study 11. Irish Energy Centre]
  • 80-93% of the electrical energy consumed by a compressor is converted into heat and not (compressed) air. [Source: SEAI Energy Agreements Programme 2007 Compressed Air Technical Guide]
  • Every 1 bar in pressure reduction produces a 6-7% power saving.[Source: SEAI Energy Agreements Programme 2007 Compressed Air Technical Guide]
  • You can achieve a 1% reduction in compressor power consumption through a 4oC reduction in inlet temperature.[Source: SEAI Energy Agreements Programme 2007 Compressed Air Technical Guide]

Compressed air energy-saving tips

  • Turn off compressed air equipment when not in use.
  • Avoid unnecessary compressed air use on drying or cleaning.
  • Do not use compressed air for: ventilation, cleaning down workbenches, floors, machinery or personnel!
  • Listen for leaks and report them immediately.
  • Keep the air inlet of the compressor in a cool area.
  • Report loose belts on compressor drives.
  • Don’t run at maximum if you don’t have to. Reduce air pressure to the minimum needed for the job e.g. 2 bar for blowguns.
  • Report older redundant distribution pipe-work so it can be blanked off.
  • Report dirty air inlet filters.
  • Report noisy compressed air equipment, as it may be faulty.
  • Adjust time switch settings to switch off equipment at lunch-times or at week-ends if it is not going to be used.

Compressed air myths

FICTIONAir is free
FACTAir is free, until it’s compressed!
FICTIONCompressed air leaks don’t amount to much really
FACTOn average, production sites leak 20 - 30% of the compressed air generated
FICTIONCompressed air doesn’t cost much, so what’s the problem?
FACTAs a power source, compressed air is about 10 times more expensive than electricity
