N Series

KAESER’s N-Series booster compressors are the smart choice for achieving high pressures up to 45 bar in specific locations without overdesigning the entire compressed air system. Perfectly matched with KAESER rotary screw compressors and SIGMA PET AIR stations, these air-cooled reciprocating boosters deliver targeted pressure increases for applications such as PET bottle production and industrial processes requiring intermittent high pressure.

Available in models from N 60 G to N 502 G, they are suited for low, medium and high flow demands. Advanced features like oil pressure lubrication, plateau-honed cylinders, and integrated aftercoolers ensure long service life, low maintenance, and cool discharge temperatures.
