AIR SYSTEMS
For air-powered tools to work their best, the air supply system must be
properly installed and maintained regularly. A drawing in this section
shows a properly installed air supply system. Handy checklists for
installing and maintaining air supply systems follow.
INDOOR AIR SYSTEM INSTALLATION BE CERTAIN
THAT:
All pipes supplying air have a large enough inside diameter to
ensure adequate air supply.
The main supply pipe slopes down, away from the compressor
(1/16 inch per foot).
Air storage is provided along lengthy air lines.
Pipe line branch outlets are at the top of the main pipe line.
Cut-off valves are provided at each branch pipe line throughout
the system.
Water legs extend from the bottom of each branch line.
A refrigerant-type dryer is installed on the system.
Air hoses are kept as short as practical.
A regular maintenance program is followed.
QUTDOOR AIR SYSTEM INSTALLATION BE CERTAIN
THAT:
A moisture trap and a filter/regulator/lubricator are installed at
the compressor.
Air hoses and fittings are large enough so that air flow not
restricted. Minimum hose size is 3/8 inch ID, with 1/2 inch ID hose
used for any application over 25 feet.
Air hoses are not longer than 150 feet.
