moisture trap and drain. Air/water filters should also be installed
in the positions shown.
Air pressure regulation
The air pressure gauge on the pressure switch measures air
pressure inside the tank, not pressure in the air line. Install an air
regulator in the drop line for each tool, to regulate air pressure to
that tool. Never exceed the maximum pressure rating of the tool.
Air lubrication
Install an air lubricator only for those tools requiring
lubrication. Do not use a lubricator for paint spraying or similar
applications. The oil will contaminate the paint and ruin the job.
Shut–off valves
Install shut–off valves in each drop line, to isolate the tool
and its accessories for servicing. You can also install a bypass
line around an accessory.
