Why 1:1 drive?
In compressed air packages featuring 1:1 direct drive the motor drives the airend directly without transmission loss via a maintenance-free coupling. 1:1 direct drive rotary screw compressors provide outstanding performance and enable significant savings.
KAESER's comprehensive range of specially designed airends are manufactured and developed to meet every compressed air user’s needs.
Triple savings with 1:1 drive: - No power transmission losses.
- Large, low speed airends provide more air for less energy.
- Significantly reduced maintenance costs.

 | SIGMA CONTROL
This internal compressor controller is a robust PC-based industrial computer with a real-time operating system and update capability. System operational status can be displayed in any one of 30 selectable languages, whilst ‘traffic light’ style LEDs indicate status at a glance.

 | Save energy with the KAESER SIGMA PROFILE
Every KAESER rotary screw airend is equipped with energy-saving SIGMA PROFILE rotors. Components manufactured to the highest standards and precision aligned roller-bearings ensure long service life with maximum reliability.
|
 | Low speed operation
Large, low speed airends are more efficient than small high speed airends because they supply more air for the same drive power. Low speeds mean less wear and consequently less maintenance costs.
|
 | Energy-saving 1:1 drive
1:1 drive reduces the number of components needed in comparison with gear drive, increasing reliability and service life through elimination of wear and transmission losses.
|
 | Powerful radial fan
The quiet and powerful radial fan draws in cool ambient air through the cooler. Its high residual thrust can deal with partial clogging of the cooler and still have enough reserve to allow connection of a long exhaust duct. In addition, the radial fan consumes significantly less drive power than conventional axial fans, saving even more energy.
