GENERAL OPERATION
The compressor is an electric motor driven, single stage screw
compressor, complete with accessories piped, wired and baseplate or
receiver mounted. It is a totally self contained air compressor package.
The standard compressor is designed to operate in an ambient
range of 1,7_C to 46_C. The standard maximum temperature of 46_C
is applicable up to an elevation of 1000m (3280ft) above sea level.
Above this altitude significant reductions in ambient temperature are
required if a standard motor is to be used.
Compression in the screw type air compressor is created by the
meshing of two (male & female) helical rotors.
The air/coolant mixture discharges from the compressor into the
separation system. This system removes all but a few PPM of the
coolant from the discharge air. The coolant is returned to the cooling
system and the air passes through the aftercooler and out of the
compressor.
Air is pulled through the coolers by the cooling fans and discharged
on the underside of the machine.
