Benefits

Quiet enclosure

Metal enclosure with insulating foam on all panels – the compressor can stand where you work.

Everything in one place

Pressure regulator, gauges and hour meter on the control panel, plus a double outlet with quick couplings.

Easy servicing

Removable panels, condensate drain on the outside and a head unloading valve.

Dryer versions too

DRY versions have the dryer built into the enclosure on a 500 l receiver.

Car repair workshop with vehicles on lifts

Car repair workshops

Air tools

Air for impact wrenches, ratchets, blow guns and tyre inflation. The receiver covers short peaks in demand without a pressure drop.

Production hall with industrial machines

General industry

Working and control air

For smaller plants and maintenance workshops with occasional or intermittent demand. For continuous, high demand a screw compressor is the better choice.
