  • Page 26 OPERATING INSTRUCTIONS GENERAL OPERATION The power transmission from the drive motor to the airend male rotor is by direct drive. The compressor is an electric motor driven, single stage screw compressor, complete with accessories piped, wired and baseplate mounted. It is a totally self contained air compressor package. By cooling the discharge air, much of the water vapour naturally contained in the air is condensed and may be drained from the downstream piping and equipment.
