PRODUCT INTRODUCTION — % Characteristic of DYF Centrifugal fans: DYF series low-noise centrifugal fan which we research, develop and produce is absorbe advanced technologies at home and abroad. 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. (l)Ventilate to civil, industrial construction, laboratory, etc. (2)applies to environment and air-conditioning system which strict required on the noise. (l)Performance parameters on catalog were test in the standard state, performance curve marked with hydrostatic (2)The gas transported by fans should be non-corrosive, non-flammable, non-explosive and without sticky (3)Working conditions: ambient temperature not exceed +60"C, not lower than -40 C, relative humidity not more than 90%, altitude no more than 1000 meters. (4)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 side, if the impeller rotates clockwise, we called it dextrorotation. Conversely, called levorotation. The wind direction has 0r , 90° , 180" and other forms if there is a support with (5)Without support of products, we can add it as you request. Also please show the fan model, specification, air flow, static pressure, the wind direction and levorotation or dextrorotation (See below) clearly.
