Benefits
Oil-lubricated single-stage pump
Low operating temperatures, low oil carry-over and little vibration for long, reliable operation.
IE3 direct drive
No belt and no transmission losses; start-stop technology eliminates energy losses during unloading.
Built to suit
Power pack for OEMs, on a base (plug & play), on a 90, 270 or 500 l receiver, or Full Feature with dryer and filters.
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.
Control and automation
Control airConstant pressure for pneumatic valves, cylinders, automatic doors and control systems. Quiet compressors with filter and regulator can sit next to the machine.
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.
Food and beverage
No oil contaminationAir for packaging machines, beverage filling and pneumatic valves where oil must never touch the product. Oil-free compressors remove that risk.
