ZUV Series Oil Free Air Compressors | Grandco Air Compressors Supplier, Air Compressors, Mitsui Seiki Compressors, AFE Filters, Oil Free Air Compressors

Clean air is simply and very inexpensively in an environment-friendly manner.

Z-screw

Fast and Easy Thermal Control Facilitates the Disposal of Waste Heat
The waste heat temperature is reduced to only one-seventh of that in a conventional oil-free air compressor. This promises the ready disposal of waste heat at sufficiently low temperatures. The water-lubricated ZU air compressor runs at about 45°C without the use of oil.

Twin screw (double-stage compression)

Equipped with an over-drive gear.

Requires a cooling lubricant.

Oil mist remover required.

With the conventional dry type (oil free), the temperature climbs to as high as about 300°C.
