Sullair 185 Model# 185DP0CA keeps shutting down

‘Inherited’ a Sullair 185 (age unknown)

Starts up great when cold and begins to build pressure up to 120 psi max…

Runs for under 3 minutes and shuts down(restarts immediately though)

No idiot lights etc…

Oil level, fuel etc is good.

Help!

To Doug from s.d. – re shutdown of 185
by: Mark

It shuts down quickly, no slugging.

But it does it much sooner now.

Thought it may have been low on compressor oil and sure enough it was quite low. Threw a gallon in and it was not enough to show on the sight glass.

Going to get more oil and even though it shuts down fast I WILL check the filter!

Turned out to be the oil pressure sending unit! Replaced and works perfect…

Thanks to all that helped.
