Roots blower advantages: 1. The fan noise, low vibration. 2. The impeller and shaft is integral structure, and impeller wear duct ventilation blower, fan performance persistent, long-term continuous operation. 3. The high speed and high efficiency blower, and the structure is very compact. The attached gear oil dumped oil installations, no leakage phenomenon. 5. No suction and exhaust pulsation, no buffer tank; 6. small footprint, ease of layout and installation high pressure blower has been widely used in sewage treatment, mining, electricity, metallurgy, light industry, building materials , chemical industry, flour, aquaculture, because of the following excellent properties makes the high-pressure blower so popular. 1, using linear impeller washing clover Roots blower, spiral structure exhaust, exhaust pulsation gentle, low noise, low vibration. 2, using a special curve makes meshing perfectly straight high pressure blower, effectively reducing the leakage and improve efficiency. 3, high pressure blower inside the enclosure without oil lubrication, and avoid the use of the bearing, gear oil mixed design chassis. The transmission medium is not oil, outlet air clean, free of any oily dust. Roots blower ventilation duct blower _ _ Zhucheng East Han Machinery Co., Ltd. provided by Zhucheng East Han Machinery Co.
