High efficiency, low noise rotary fan

Companies leading products RFSR clover Roots blower and rotary fan by years of design and manufacturing experience of key personnel. The product has a reasonable structure, small size, high efficiency, low noise, smooth operation, long life, easy maintenance features, has been widely used in sewage treatment, pneumatic conveying, mining, chemical, metallurgy, building materials, electricity, flour, vacuum packaging and aquaculture industries. Companies to high quality, quality service, competitive price and customers create a win-win situation. Product Type: RFSR50, RFSR65, RFSR80, RFSR100, RFSR125, RFSR150, RFSR200, RFSR250, RFSR300 other products. Product features: compact structure, small size, light weight, smooth operation, low noise, energy efficient, low appearance 1. noise, the fan intake and exhaust ports spiral shape, the intake and exhaust process according to spiral. The direction of progressive cut to avoid the outbreak of the moment when the old exhaust fan pulsation noise and vibration. 2. adiabatic efficiency and high volumetric efficiency, thus saving. Fan rotor using advanced composite curve, the meshing is more reasonable, and increases the volumetric efficiency. 3. stable performance. Key parts fan rotor casing, wall panels, shaft, using advanced CNC machining equipment, improve interchangeability of parts. 4. vibration. Rotor through precision machining, and high-precision balancing equipment balance calibration, so the fan operation without vibration. 5. The use of high-precision, high hardness synchronization gear, not only the life of the fan has been extended, but also effectively reduce the noise. 6. This series of fans bearing US imports of bearings, product quality and more reliable. 7. The output of the air clean and free of any oil and dust, fan sealing structure is reasonable, so that oil can not enter the chassis, thus the air clean. HZ25-100 series rotary blower, small size, air volume, low noise, ideal for hospitals, sewage treatment and other residential district.
