Rotary Screw Compressors With 1:1 Drive To 500 kW

Rotary Screw Compressors With 1:1 Drive To 500 kW

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.
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
The motor and airend are joined by the coupling and its housing to form a compact and durable unit that is virtually maintenance-free. Furthermore, reliability and service life are increased through elimination of wear and transmission losses, as 1:1 drive reduces the number of components needed in comparison with gear drive

Radial fan: Quiet and efficient
The quiet and powerful radial fan draws in cool ambient air through the cooler. Its high residual thrust allows the use of exhaust ducting without the need for an additional extractor fan. In addition, the radial fan consumes significantly less drive power than conventional axial fans, saving even more energy.
