摘要： A compressor or blower includes an impeller disposed on a high-speed shaft, a motor shaft that extends from an end shield of a motor, a gearbox, and a lubrication system. The gearbox is disposed between the motor and the impeller and includes a pinion disposed on the high-speed shaft and a bull gear disposed directly on the motor shaft in engagement with the pinion. The lubrication system includes a single pump module that is configured to wet bearings on the high-speed shaft prior to starting the motor and to mechanically pump oil to the bearings during operation of the motor.
