Compressed air

Easy ways to cut compressed air energy costs and keep your system running smoothly.

Compressed air is handy, but it can be one of the most expensive energy users in your business. A few smart tweaks can help you save money, reduce waste and keep everything humming along nicely.

Operate compressed air systems efficiently

Small habits, big savings:

  • Use compressed air only when you genuinely need it, and shut down the main compressor when your business is closed
  • Keep air pressure as low as possible. High pressure increases leaks, strains equipment and drives up costs
  • Set discharge pressure to the minimum your system requires

Choose the smallest compressor that meets your needs. Smaller units run more efficiently at full load. One big, underused compressor often costs more to run than two smaller ones working properly.

Choose energy efficient compressor systems

Smart upgrades can pay for themselves:

  • Add a variable speed drive (VSD) to your existing system and you can save up to 50% on energy
  • Replace old filters with energy‑efficient ones that create less pressure drop
  • Swap old drain valves for electronic sensing drains. They only discharge when needed and can save you up to five times their purchase price each year
  • Install air storage to smooth out demand, improve air delivery and reduce electricity use
  • Use automatic sequencing so compressors work together efficiently instead of competing
  • Install shut‑off timers and microprocessor controls to avoid unnecessary run time
  • Keep the distance between your compressor and your tools as short as possible. Less distance, less energy
  • Make use of heat recovery. Up to 90% of a compressor’s energy ends up as heat, and you can reclaim around 80% of that for things like heating water
  • Fit pressure regulators so your system never uses more air pressure than it actually needs.

Look after your equipment

  • Air leaks can waste 20% to 30% of the energy in a compressed air system and cause pressure swings that make tools less effective
  • Set up a regular maintenance schedule to check valves, joints, hoses, drains and fittings. Hunt down leaks early
  • Make sure the V‑belt isn’t too loose or too tight, as both put unnecessary load on the motor and compressor
  • Keep dirt out of the compressor so filters stay clean and airflow stays strong
  • Use a timer and solenoid valve to keep the air receiver in good shape. Drain it regularly, and position air intakes where they can draw in the coolest possible air
  • Check that the purge cycle on dryers isn’t running longer than needed.
