Air Distribution System

Plastic or PVC pipe is not designed for use with compressed air. Regardless of its indicated pres-

sure rating, plastic pipe can burst from air pressure. Use only metal pipe for air distribution lines.

The next figure represents a typical air distribution system. The following are tips to remember when setting up the air compressor’s air distribution system.

●Use pipe that is the same size as the air tank outlet. Piping that is too small will restrict the flow of air.

●If piping is over 100 feet long, use the next larger size.

●Bury underground lines below the frost line and avoid pockets where conden- sation can gather and freeze. Apply pressure before underground lines are cov- ered to make sure all pipe joints are free of leaks.

●A flexible coupling is recommended to be installed between the air discharge outlet and main air distribution line to allow for vibration.

●A separate regulator is recommended to control the air pressure. Air pressure from the tank is usually to high for individual air driven tools.

MAIN DISTRIBUTION AIR LINES Slope pipe in direction of air flow. Water condensate flows along bottom of pipe to drain legs, preventing it from entering feeder lines.
