Air Compressor Tips and Tricks
Simply following our air compressor tips can offer you energy efficiency improvements of between 20 to 50 percent. It is very easy to save energy and operating costs on your compressed air system by:
- Maintaining your air compressor system regularly.
- Selecting the correct air compressor for your needs.
- Optimising the size of your air distribution system.
- Controlling air quality.
Simple Changes To Save You $ Thousands
- Turn off compressed air equipment when not in use.
- Reduce air pressure to the minimum required to do the job.
- Prevent unnecessary compressed air use on drying or cleaning.
- Educate staff to look out for waste and leaks, and report these immediately.
- Hot air ducted away from the air compressor intake area can be used for space or water heating.
Low Cost Improvements
- Regularly check for leaks in all piping, joints, drains, valves, flexible hoses, fittings, and filter and lubricator units. For example, a 6.4mm hole could waste $3,400 per year on an air compressor system operating at 700kPa.
- Install automatic timers to turn off your air compressor when not in use.
- Service your air compressor as recommended by its manufacturers.
- Reduce air temperatures, as the temperature of the air drawn in by your air compressor can significantly affect running costs.
- 6% of energy can be saved by using cooler air from outside your air compressor room.
- Shorten air distribution distances or look at moving your air compressor closer to where your compressed air is used.
- Check all belt drives for tension regularly in belt-driven air compressors. Energy losses due to incorrect tension due to excessive stress on air compressors and motor bearings are common.
- Select the air compressor size that runs most efficiently when it is run at ‘full load’.
- Ensure that your air compressor matches your needs, and do not install an oversized compressor to meet anticipated future demand. Purchasing an additional, appropriately sized air compressor when needed later is usually more economical and efficient.
- Consider energy efficient accessories to minimise energy losses in compressed air systems such as high efficiency filters and dryers, or choose a compressors with variable outputs.
- Choose appropriately sized air receivers to act as a buffer between output and demand.
- Request a power cost calculation or a compressed air audit is conducted.
