Benefits
For heavy, long-running work
Designed for large air volumes, high pressure and a long service life.
Robust build
Aluminium heads, cast-iron cylinders, stainless steel reed valves and an oversized crankcase.
Easy to move
Rubber rear wheels and braked front wheels.
Car repair workshops
Air toolsAir for impact wrenches, ratchets, blow guns and tyre inflation. The receiver covers short peaks in demand without a pressure drop.
Tyre services
Tyre inflationFitting and inflating car and van tyres. For truck and tractor tyres, choose a two-stage compressor rated up to 15 bar.
Metalworking
ProductionWorking and control air for machines, fixtures, pneumatic cylinders and blow-off. Two-stage compressors deliver more air at higher pressure.
General industry
Working and control airFor smaller plants and maintenance workshops with occasional or intermittent demand. For continuous, high demand a screw compressor is the better choice.
