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 plumbed-in air distri-
bution system. Follow these instructions to correctly convert to a permanent 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.
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 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 oil-free filtered air.
•
Drain all traps, filters and dirt legs daily.
