Description

Split type 
The air end and the motor are connected separately, which is easier for installation, dismantlement, and maintenance.

Backward curved centrifugal fan
An optional backward curved centrifugal fan uses an impeller to increase airflow. In addition, during the operation, the centrifugal fan features no friction, low noise, no dust, and easy maintenance.

Patent design of inlet valve

The sinking gravity sensor oil stop valve effectively stops the oil reverse and largely reduces the inlet obstruction loss.
