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.
