Air Distribution System - Porter-Cable C7550 Instruction Manual

Voltage and Circuit Protection
Refer to the specification chart for the voltage and minimum branch circuit
requirements.

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 (30.5 m) long, use the next larger size.
•
Bury underground lines below the frost line and avoid pockets where con-
•
densation 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.
FEEDER LINES SLOPE
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.
