Two-Stage Industrial Rotary Screw Compressors

Sullair two-stage tandem compressors use two sets of rotors arranged in an end-to-end design for unmatched full-load and part-load efficiency, and a two-year payback on energy savings compared to a single-stage compressor. Capacity is matched to system need for reduced cycle time and longer life. These units are 13% more efficient than single-stage screw compressors at full-load operation and 30% more efficient at part-load.

Models vary by region. Please contact your Sullair sales representative for more details.
