It’s not unusual for leaks to consume 20 to 30 percent of compressor output, which can cause up to thousands of dollars per year in unnecessary electricity costs. Moreover leaks reduce system pressure, which in turn would affect production. After estimating the amount of leakage occurring, the next step is to find and eliminate the leaks. The easiest and the fastest way to find leaks are with a tool called an ultrasonic leak detector. Once you’ve found a leak, eliminating it is often a matter of simply tightening the connection. Sometimes it will be necessary to open a joint, clean the threads, and apply the appropriate thread sealant. In some cases you may find that you need to remove and replace faulty equipment. Ensure that air supply to all equipment is shut off when that equipment is not in use; solenoid valves are available to automate that process.
