About the Sullair 375 Construction Air Compressor
The Sullair 375 construction air compressor is what is termed as a portable. It is designed and built to be towed to a construction site, and there to provide up to 375 CFM of compressed air at 100 PSI.
Being a construction compressor, the power plant is a gasoline or diesel fueled internal combustion engine, driving a rotary screw compressor.
In 2018 the new 375 has a number of power plants available, including the: Caterpillar CATC4.4 (T2), an Inline 4, 4-Stroke-Cycle Diesel or a John Deere JD4045HF cylinder inline diesel.
Designed for field use and user convenience, the new Sullair 375 offers lage service doors, multi-piece canopy for ease of partial or complete canopy removal for greater compressor service, complete highway-towable trailer package, and a curbside instrument panel for user convenience, among many other features.
Sullair has been building portable rotary air compressors for construction use since 1965 at their Michigan City Indiana location, and via their international supplier in China, and sell their compressors world-wide.

I have a 375 sullair air compressor having issues with throttling up it wont idle up when switching over. I replaced the pressure transducer and no change it has the john deere motor. Im looking for the throttle position location.
Does it make normal pressure with no load?
What is the best type of oil to use in an old sllair 375air compressor
I have a 425 cfm when oil in air resivor gets hot it shuts down wondering how hot oil suppose to get it seems to hot to me and gets there in about 5 min after starting air barely on I suppose it has a kill to motor if gets to hot I just put new oil to see if that helped what about separator filter can that make it get hot or bearing on screw itself
What model?
But yeah, generally there is a kill if it gets too hot. 210 F is a common shutdown temp..
Is the radiator getting hot? If not, you may have a bad thermostatic bypass. Works the same as the water thermostat in a car… Or a clogged filter.
You checked anything else? Do you know if this come on suddenly or gradually or ?
