DG SERIES

Industrial Electric

25-50 HP

Developed to be dependable and efficient, the DG-Series industrial electric direct gear drive air compressor is another versatile Sullivan-Palatek product. The DG-Series compressors offer a range of 25-50 hp. The compressor is a continuous duty, and fluid flooded rotary screw that is directly coupled to the motor for positive alignment. The compressors compact size makes it the ideal product for smaller industrial settings such as food processing, automotive shops and fabrication workshops.
