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, two or three cylinders and operate within the following performance parameters:

  • Initial pressure up to 13 bar – discharge pressure up to 45 bar
  • Flow rate: 0.27 – 20.51 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 compressionthan 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.

  • For lower demand

    The smaller models in this range are best suited to applications where low flow rates are needed at pressures up to 40 bar. These compressors are equipped with one- or two-cylinder compressor blocks and are driven by high efficiency motors with up to 4 kW capacity. The quality of these units is second to none as all compressor blocks are designed, manufactured and assembled by KAESER.


    For medium to large demand

    When greater air flow rates are needed at pressures up to 45 bar then the mid-size and larger of the Kaeser booster models are the natural choice. At the heart of every one of these powerhouses is a precision machined two- or three-cylinder compressor block that delivers exceptional efficiency. Premium-efficiency electric drive motors up to 45 kW provide optimal energy efficiency (up to 18.5 kW: IE2, from 18.5 kW: IE3).



    The N 2001 G air-cooled versions are equipped with a separate fan-assisted aftercooler to keep the temperature differential between the inlet and compressed air (ΔT) within close tolerances. To ensure optimal cooling performance with a ΔT value of only approximately 5 K even at high ambient temperatures, the N 2001 G models can be equipped with a water-cooled compressed air aftercooler.
