Compact design with impressive performance
Kaeser rotary screw compressors with V-belt drive provide outstanding efficiency and reliability. an energy-saving SIGMA PROFILE airend and a SIGMA CONTROL controller to ensure outstanding efficiency and performance. You can choose from four series with these technical parameters:
- Pressure: 8, 11 or 15 bar
- Flow rate: 0.26 – 4.65 m³/min
All series are available as standard models but also with
- Add-on refrigeration dryer for high compressed air quality and/or
- Speed-controlled motor for a large flow rate control range. (SM, SK and ASK series)
We will gladly tell you which model is the perfect solution for you.
Your advantages
- Highly-efficient power transmission:
The quality drive belt with automatic tensioning device ensures consistent transmission efficiency and excellent drive system reliability over the entire service life. - Easy maintenance:
The housing is easily opened. All components are logically arranged and easy to access. Maintenance work is therefore made quick and simple. - Exceptionally quiet:
The soundproofed housing reduces operational noise to a minimum. Normal conversation can take place right next to the compressor.
Profitable thanks to low life-cycle costs
Our comprehensive approach to optimal profitability: Optimal efficiency, easiest operation, service-friendliness and a global service and consulting network with fast response times.
