Compressed Air - Porter-Cable C7501 Instruction Manual

NOTE: Compressed air from oil lube air compressors will contain wa ter condensation
and oil mist. Several drains, traps and filters will be needed to supply air without
water (including aerosols) or oil to spray equipment, air tools and accessories
requiring filtered air. Always read the in struc tions for the air tools and accessories
being used.
• 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
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 globe valve/
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.
• DO NOT install lubricators between the tank and any spray equipment, air tool
or accessory requiring oil-free filtered air.
• Drain all traps, filters and dirt legs daily.

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.
