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 4 constant speed models ranging from 300 to 450 kW, 1942 to 2900 cfm (55 to 82.1 m3/min), and 6.9 to 10.3 bar.
