Product Description

 

Low-noise and Multi-plane Centrifugal Ventilator

Performance introduction



 centrifugal ventilator with low-noise and multi-plane is designed and produced for the fast-developing purification industry and noise reducing for environmental protection. In order to achieve the performance-matching optimum and better aerodynamic performance of whole ventilator, the optimized multiple-target design method has been taken into account when designing the ventilators with various aerodynamic parameters such noise, efficiency and so on. 
 
With the dynamic balance strictly checked, the impellers are characterized with smooth operation, low noise, heavy flow, small vibration and long operating life and so on. This greatly applicable product is widely used for wind-discharging, fume extracting and ventilating in kitchens of company canteens, hotels, restaurants, and other public places, as well as the production facilities' such as foodstuff machines, chemical machines and plastics machineries.
