Air-cooled

In the absence of a cooling-water infrastructure, air-cooled, oil-free compression rotary screw compressors ensure exceptional compressed air supply dependability – even in ambient temperatures up to +45 °C.
There’s also plenty of power: thanks to innovative and intelligent system design, we can provide air-cooled, oil-free compression rotary screw compressors up to 355 kW.
* Flow rate from 3.2 to 50.8 m³/min
* Durable, stainless steel-aluminium cooler combination
* Also available as a peak-load model with variable speed control and frequency converter (SFC model versions)
* Also with integrated i.HOC rotation dryer

Your benefits

Heat-use made simple:
Thanks to radial fans with high residual thrust, the heated cooling air can normally be used straight away for space heating without need of auxiliary fans.

Energy-efficient in every detail:
In standby mode, the temperature-controlled Kaeser standstill fan reliably conveys residual heat away – meaning the main fan can be switched off!

Exceptionally maintenance-friendly:
The first and second stages of the aluminium-block heat exchanger can simply be swivelled out for cleaning purposes.

Hydraulic inlet valve
The hydraulically operated inlet valves in Kaeser oil-free compression rotary screw compressors are unaffected by contamination and condensate. This makes them more reliable and easier to maintain than pneumatic valves.
Fibre-free pulse dampers
Kaeser’s new fibre-free pulse dampers keep pressure losses to an absolute minimum, help maintain consistent air quality and, unlike fibre versions, do not present a source of contamination for the compressed air.
Reliable oil reservoir venting
The microfilter in the oil tank venting system prevents the intake of oil-laden air – a key detail to ensure that compressed air quality is reliably maintained at all times.
Highly efficient condensate separator
Thanks to its flow-optimised design, the newly developed condensate separator reliably separates the condensate downstream from the air coolers, with minimal pressure loss.
