Reducing Demand

Minimize air leaks: Do you hear hissing? That's the sound of money escaping. It is not uncommon for 20-30% of a compressor's output to be lost to waste.

You can find leaks with an ultrasonic acoustic detector. Some detectors allow you to estimate the size of each leak. Click here to purchase a leak detector from UE UltraSonic. Click here to lease one from us.

Use our Leak Calculator to figure out how much leaks are costing you - and what kind of savings you could recover. For more background on system leaks, see the Compressed Air Challenge® (CAC) Fact Sheet #7.

It's not uncommon for the compressed air system to have grown over time, with more devices being added and upgraded, and while other equipment may have been retired. Along the way, leaks happen, more users tap into the system, and piping and air-receivers layout may no longer be efficient.

• Who are your compressed air consumers? What equipment or processes are using the most air?
• How much air pressure do they need?
• How far away are your compressed air consumers from the air compressor(s)?

Eliminate inappropriate users: Think of compressed air as a utility, just like water, gas, and electicity. It is one of the most convenience and easy-to-use resources in your plant. It is often the most expensive of your utilities.

Are there applications using compressed air that could be replaced through less expensive means? For example: Is compressed air used for drying or cooling? Blowers and HVAC are only a fraction of the cost of compressed air. We give you a list of situations to watch out for. For other examples of inappropriate use see CAC Fact Sheet #2 and the US Department of Energy Compressed Air Tip Sheet #2 and

Reducing air pressure: Because of inefficiencies in the compressed air system, many systems operate at a higher air pressure than is really necessary. For example, a machine in the plant may require 100 psi to operate properly. But, because of its distance from the nearest air compressor, the system's air pressure must be raised to 125 psi so that 100 psi gets delivered to that machine. According to (CAC Fact Sheet #4), a properly designed system should have a pressure loss of much less than 10% of the compressor's discharge pressure, measured from the receiver tank output to the point of use. Any leaks in the system are exaggerated by running at a higher air pressure.
