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' (30.5 m) 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
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.

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