Chapter 6 Compressor Operation
57
Compressor Operating Conditions
If possible, operate the compressor with the truck as close to level as possible. The compressor
will operate on a 15° tilt from side to side and end to end without adverse problems. Fluid carry
over and/or oil starvation may occur if operated at a tilt beyond 15°. Operation in ambient
temperatures above 100° F may result in high temperature shutdown.
NOTE
If the compressor is being used to power sandblasting equipment or an air storage tank, use a
check valve directly after the minimum pressure orifice to prevent backflow into the sump.
This check valve should have a maximum pressure drop rating of 2 PSIG (13.78 kPa)
operating and a capacity rating equal to the compressor.
NOTE
When a hose reel is not used, the compressor service valve should be relocated to the hose reel
inlet, or to a customer-supplied air connection port. Typical plumbing from a minimum pressure
orifice should flow in the following order:
1
Minimum pressure orifice
2
Check valve
3
Air tank (when used)
4
Service valve
5
Moisture trap/ gauge / oiler combination (when used)
6
Hose reel (when used)
