Roots blowers can be roughly divided according to different single-stage and two-stage blower buy points, only one compression stage blower blower applications of their work, which we call single-stage blowers, and the two single stage blowers together, for two consecutive compressed gas blowers we call the two-stage blower. Divided by Transmission: direct connection with fans and blowers Union; divided by Cooling: air cooling fans, blowers and water-cooled counterflow cooling blowers; by structure type: Vertical blowers, blower horizontal, vertical shaft blowers, densely into blowers and other groups; press seal type points: labyrinth seals, piston ring seals, packing and mechanical seals and other various types of blowers. Lobe Roots Blower is our introduction and absorption of foreign advanced technology Roots blower, the use of CAD-aided design clover Roots blower, computer aerodynamic testing system and advanced processing equipment, leak-free seal with a unique way, using a unique composite impeller profile design, saving 5% than the traditional process, reasonable structure, small size, high efficiency, low noise. Lobe Roots Blower Uses: widely used in the field of wastewater treatment, mining, metallurgy, chemicals, building materials, electricity, light, flour, aquaculture and other purchase Roots blowers, blower, Zhucheng East Machinery Co., Ltd. by John Zhucheng East Han Machinery Limited.
