An outstanding feature of VCC compressors is Sullair’s unique capacity control system, which consists of a spiral valve and an inlet butterfly valve. This system delivers greatly improved part-load performance, especially when compared with compressors having suction throttling or load/no load controls.
Compressed air volume is varied by rotating the spiral valve, which opens and closes by-pass ports in the stator, and returns air to suction rather than compressing it. By matching compressor displacement with output need, this energy-saving system uses up to 17% less power.
Since the removal of condensate is essential for quality air, Sullair has taken the guesswork out of matching compressors to dryers. Sullair’s integral dryers have been perfectly matched and sized to your compressor to provide maximum performance, without paying for more than you need.
