Sullivan-Palatek has developed the D-Series industrial electric direct drive rotary screw air compressor, which is designed to be dependable and versatile. These energy-efficient compressors come in a range of 15-40 hp and are equipped with an easily readable microprocessor. The coupling and air end are mounted to the motor C-face for convenience.
The D-Series compressors also feature a sizeable oversized separator element and sump tank, as well as easily replaceable oil and air intake filters. With their compact size and high reliability, these machines are perfect for smaller industrial settings like automotive shops, small machining facilities, and fabrication facilities. Additionally, the D-Series compressors have many easily accessible parts, resulting in a lower overall cost of ownership compared to our competitors.
Features & Benefits
