Air leaks are a concern for anyone operating a compressed air system. The average plant with no formal leak management program will have air leaks that waste up to 30 percent of the total air capacity.

Leaks will cause compressors to run at full load for longer periods of time. The compressors will not only use more energy but, may also need additional maintenance due to the increased loads.

Leaks can give the false impression that additional compressors are required to meet the demand for compressed air.

Common Leak Points

• Quick connection fittings have o-rings to seal the hose connections. A damaged or missing o-ring will cause the connection to leak.
• FRL's (filter, regulator & lubricator)
• The welds found on pipe joints and pipe flanges can leak due to vibrations, age or improper welding.
• Float or mechanical type condensate drains are also a source of air leaks.
• Pipe thread connections, air tools and many more sources can be the cause of air leaks.
