Blowers And Fans
External Rotor Centrifugal Blowers And Fans
DYF Series low –noise centrifugal fan which we absorbed advanced technologies at home and above to research, develop and produce. All the structural parts of this series fan are using the mold production, and the impeller have been static and dynamic balance proofread, so our products are small volume, little vibration, low noise, high efficiency, large air volume, easy to install. Debug and so on. Our centrifugal fan is the ideal accessory products to the air-conditioning, purification, refrigeration and other industries
Features
Performance parameters on the catalog were test in the standard state, performance curve marked with hydrostatic pressure
The gas transported by fans should be non-corrosive, non-flammable, non-explosive and without stick substances
Working conditions: ambient temperature not exceed +60℃, not lower than -40℃, relative humidity not more than 90%, altitude no more than 1000 meters
Fan divide into levorotation and dextrorotation. Face the end inlet of single-inlet centrifugal fan, and face the double-inlet centrifugal fan from the wire outlet, if the impeller rotates clockwise, we call it dextrorotation. Conversely, called it levorotation. The wind direction has 0°, 90°, 180° and other forms if there is a support with fan
Without support of products, we can add it as your request, also please show the fan model, specification, air flow, static pressure, the wind direction and levorotation or dextrorotation clearly
Application
Ventilate to civil, industrial construction, laboratory, etc
Applies to environment and air-conditioning system which strict required on the noise
