The new N 60 G offers commercial vehicle workshops a cost-effective and energy-saving source of 25 bar compressed air.
Generally the most economic means of supplying this demand is to use a rotary screw compressor to produce the 6 bar air and a booster to compress some of this air further to the higher pressure needed. The N 60 G is the booster offered by Kaeser as the most cost-effective solution for this application.
This new machine, a single cylinder reciprocating compressor with a 2.2 kW drive turning it at the relatively low speed of 1040 rpm, takes shop air at about 5 bar and boosts it to a final pressure of 25 bar at the rate of 280 litres per minute. The machine uses a highly efficient oil lubrication system and can be equipped with pre and final pressure monitoring. Low maintenance V-belts provide optimum power transmission from the motor to the compressor block pulley that also acts as a fan to blow cooling air over the cylinder head. A generously dimensioned aftercooler brings down the temperature of the boosted air to suit downstream treatment components. The combination of an N 60 G booster and a Kaeser rotary screw or reciprocating compressor provides a cost-effective, energy-saving and highly reliable source of 25 bar compressed air at for the above and other applications.
