When greater volumes of air are needed at pressures up to 45 bar then the larger of the KAESER booster models are the natural choice. The core of these powerhouses is the high-precision, two- or three-cylinder compressor block with specially finished high quality cylinders and premium efficiency Eff1 motors providing capacities up to 45 kW. 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 after-cooler versions are available (N 253 G – N 502 only air-cooled, from N 753 G air- or water-cooled after-cooler). Air-cooled versions ((N 753 G - N 2001 G) are equipped with a separate fan-assisted after-cooler to keep the temperature differential between the inlet and compressed air (ΔT) within close tolerances. To ensure optimum cooling performance with a ΔT 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. |
