Your Bottom Line Is Leaking

One of the most common types of facilities that I visit is a manufacturing facility. They utilize large amounts of compressed air for machines and tools Many of my customers spend large amounts of money on their compressed air system. This money is used for energy and maintenance of the system. Inefficient and improperly operating compressed air systems can be causing your bottom line to ‘leak’ money. The compressed air system needs to be examined and audited like any other building system. The steps to driving savings to your bottom line are as follows:

  1.   The first step is to record and document the existing system. This may include consumption patterns.
  2. The second step is to determine the baseline or existing performance of the compressed air system. This involves determining the energy used to compress air under normal conditions.
  3. The third step is to test the system. This involves checking for leaks with an ultrasonic tester and measuring the leak down time of the compressor is possible.
  4. The fourth step is to determine a plan of action to reduce the waste. This may include equipment repair or replacement as well as changing consumption patterns.

The compressed air system may be leaking money out of your bottom line!
