Air Distribution System
Risk of Unsafe Operation. Unit cycles automatically when power is on. When servicing, you may be exposed to voltage sources, compressed air, or moving parts. Before servicing unit unplug or disconnect electrical supply to the air compressor, bleed tank of pressure, and allow the air compressor to cool.
IMPORTANT: The regulator assembly on the unit should be removed and a flex- ible coupling should be assembled to the pipe nipple for a
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.
NOTE: Compressed air from oil lube air compressors will contain water 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 instructions 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 pipe nipple 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
•Drain all traps, filters and dirt legs daily.
