Roots Blower Features: ● As a result of clover with helical wheel and linear box, so the fan noise vibration is small. ● impeller and shaft for the overall structure and impeller wear, fan performance enduring, long-term continuous operation. ● High-speed high efficiency and very compact. ● Simple structure dust blower power plants, the use of special bearings, with superior durability, longer life than domestic fan ventilation duct blower, and maintenance management is also convenient ● As with gear oil dumped oil powder delivery device Luo Mainz blower, so no leakage phenomenon. Roots blower advantages: (1) between the blower rotor and the rotor, the rotor and the housing to retain a gap between 0.2-0.5mm, there is no friction phenomenon Roots blower, allowing a gas stream containing some dust; (2 ) compared with the water jet blower and water ring vacuum pump, not "exhaust with water" problems; (3) Roots blower reliable operation, easy maintenance and durability.
