Rotary Screw Air Compressor (Integrated with a Freeze Dryer and Filter)

Diverse industries including electronics, pharmaceutical and textiles require the use of quality air compressor equipment and compressed air solutions.

As our general purpose air compressors are reliable, compact and quiet, they have become a popular choice for supplying clean air to various industrial factories in residential areas.

When running at 22kw, the general purpose air compressor creates a noise level as low as 66dB without causing any vibrations. The one-piece compressor design allows for an easy installation, use and maintenance.
