Air Distribution System
Risk of Bursting. Plastic or PVC pipe is not designed for use
with compressed air. Regardless of its indicated pressure
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
condensation can gather and freeze. Apply pressure before underground
lines are covered 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.

Water condensate flows along
