Available for capacities (flow rate) 0.6 to 824.6 m3/min, and for pressure 9.8 to 98kPa.

Brief features:
Fast start
Less power consumption
Low operation and maintenance costs, pumping speed, high efficiency, not sensitive to the small amount of water vapor contained in the pumped gas and dust
with greater pumping rate that can quickly rule out the sudden release of gas
Pressure range is connected in series between the oil seal mechanical vacuum pump and spread pump to increase the outlet volume of the intermediate pressure range.
