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 approximately 13% more efficient than single-stage screw compressors at full-load operation and around 30% more efficient at part-load. Sullair offers 3 constant speed models ranging from 185 to 260 kW, 1021 to 1845 cfm ( 28.9 to 52.3 m3/min), and 6.9 to 12.1 bar.
