The Biggest & Worst. Tales from a Compressed Air System Auditor’s Personal Notebook
By Chris E. Beals, President of Air System Management, Inc.
Years ago, while managing the service department of my compressor distributorship, I received a call from a nearby customer who told me his 200hp compressor wouldn’t make any air.
