Design

Premium compressor design and industry leading warranty

The compressors are equipped with a premium high efficiency electric motor, which can be upgraded to an ultra efficient energy saving IE4 electric motor.

The RS (regulated speed) efficiently handles the varying air demand found in most plant air systems. The compressors incorporate quality components, such as high performance separator filter, large surface after cooler and thermostatically controlled motor driven fan.

The design concept is not only based on energy efficiency but also on high availability and low maintenance costs.

Therefore these packages ensure all service points are easily accessible. The reduced number of moving parts contributes to lower maintenance costs additionally.

Premium Efficiency Airends

The new airend rotor profiles deliver exceptional efficiency and flow rates while reducing noise and vibration levels.

The semi-integrated design allows a small compressor footprint and ease of maintenance with less piping and less leakage risk with integrated thermostatic valve, oil filter and discharge on top.

Our top quality airends are covered by the new 10 years warranty and up to 44,000 hours.
