Air Distribution System
Plastic or PVC pipe is not
designed for use with com-
pressed 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 set-
ting up the air compressor's air distribution system.
Use pipe that is the same size as the air tank out-
●
let. Piping that is too small will restrict the flow of
air.
AIR FLOW
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.

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 usu-
ally to high for individual air driven tools.
