"SELECT THE INDUSTRY'S FINEST COMPRESSORS"
Air Systems offers the full line of Kaeser built rotary screw air compressors. These systems are designed and built specifically for breathing air in Germany. Systems are available up to 3000 cfm. They operate by drawing air in through a filter where it is cleaned prior to compression. The atmospheric air is then compressed within the efficient Sigma screw air end. The Sigma screw air end is driven by an electric motor. Oil is injected into the rotor housing to lubricate, seal and remove the heat generated by compression. As a result of this internal cooling mechanism the temperature during compression reaches only 180 degrees Fahrenheit under normal conditions. Oil is separated from the compressed air stream by the 3 stage oil/air separator. The separated oil is cooled in the oil cooler, flows through the micro oil filter and returns to the injection point. This oil circulates solely by internal pressure, eliminating the need for an oil pump. The oil temperature is controlled over the entire range from cold start to full load or idle operation by an oil thermostatic valve. The compressed air is separated from the injected oil in the oil separator cartridge, and is passed to the aftercooler via the minimum pressure check valve. This valve maintains minimum system pressure to ensure continuous oil injection into the airend. The temperature of the compressed air is cooled to within 10-15 degrees Fahrenheit of the ambient temperature by the air cooled aftercooler, thus removing a large percentage of moisture from the compressed air.
