The purpose of compressed air piping system is to deliver compressed air to the points of usage. The compressed air needs to be delivered with enough volume, appropriate quality and pressure too. Compressed air is costly to manufacture. A poorly designed compressed air system can increase energy costs, promote equipment failure, reduce production efficiencies and increase maintenance requirements. It is generally considered true that any additional costs spent improving the compressed air piping system will pay for themselves many time over the life of the system.
