When greater volumes of air 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 with high quality compressors and exceptional efficiency,
whilst IE3 premium efficiency electric drive motors up to 45 kW provide impressive performance.
The manual (two-cylinder models) or automatic drive belt tensioning systems (three-cylinder models) ensure constant efficient power transmission for reliable and economic operation.
According to application, air-cooled or water-cooled aftercooler versions are available (N 253 G – N 502 only air-cooled, from N 753 G air- or water-cooled aftercooler).
Air-cooled versions ((N 753 G - N 2001 G) are equipped with a separate fan-assisted aftercooler to keep the temperature differential between the inlet and compressed air (∆T) within close tolerances.
To ensure optimum cooling performance with a ∆T value of only approximately 5 K even at high ambient temperatures, models N 753 to N 2001 can be equipped with a water-cooled compressed air aftercooler.
