Water Treatment Roots Rotary Lobe Blower, high pressure 100KPA air compressor
The Roots-type blower is a positive displacement lobe pump which operates by pumping a fluid with a pair of meshing lobes resembling a set of stretched gears. Fluid is trapped in pockets surrounding the lobes and carried from the intake side to the exhaust.
BKW blower can be used for various industries, such as for separating small particles and algae in groundwater, recovering valuable products in industrial sewage and so on. It can reach the air capacity of 3900 m3/h under 80KPA rising pressure.
