Your ticket to high-pressure performance
N-series boosters augment your existing system pressure in specific locations, elevating it up to 45 bar. Kaeser offers an extensive range of high-performance booster reciprocating compressors that work in perfect harmony with Kaeser rotary screw compressors and SIGMA PET AIR stations.

The N-series boosters are available with one or two cylinders and operate within the following performance parameters:

Initial pressure up to 13 bar – discharge pressure up to 45 bar
Flow rate: 0.27 – 5.49 m³/min
Compared to designing the entire compressed air supply system for higher pressure, the use of boosters is significantly more cost-effective for all applications that require process air with a higher degree of compression than the normal control air and supply air at specific locations. PET bottle production is an excellent example of such applications.

Your advantages

Continuous high-pressure operation:
Innovative features such as oil pressure lubrication and intensified cylinder cooling ensure both long service life and low maintenance requirements as well as continuous system-compatible maximum pressure of 45 bar.
Exceptionally low oil requirement:
The high quality cylinders are plateau-honed and feature an extra layer of wear protection. These details ensure low oil consumption over the entire service life.
For especially cool compressed air:
The compressed air aftercoolers on the three-cylinder boosters are equipped with separate fans, which ensure low compressed air discharge temperatures. The boosters can be additionally equipped with water-cooled aftercoolers to attain even lower temperatures.
