D-Series Compressors D-Series Compressors

Engineered to be both dependable and versatile, the D-Series industrial electric direct drive rotary screw air compressor is one of many energy-efficient solutions developed by Sullivan-Palatek. The D-Series compressors are offering a range of 15-40 hp. They are equipped with an easily readable microprocessor, a coupling and air end mounted to the motor C-face. It utilizes a sizeable oversized separator element & sump tank as well as easily replaceable oil & air intake filters. With their compact size and high reliability, these machines are ideal for smaller industrial settings such as automotive shops, small machining facilities, and fabrication facilities.

The D-Series compressors utilize many easily accessible parts, making the overall cost of ownership much lower than many of our competitors.
