Advantage:

1. Motive power system adopt width protection IP55 grade as driving, to accomplish turbine circle suction strength with lower nosie , higher pressure ,larger rate of flow 

2. Filter system adopt advanced mechanical filter technology in the present water technology,can effective dislodge rubber mass and other solids

3. high efficiency & twice water and air separation system can prevent liquid & blood and bloody bulla of pipeline to suction vacuum pump.high foam compatibility. During high rate of flow, it still have stable separation efficiency. small obstruction , simple maintenance.
