Product description

Ⅰ. Features of fan
DKF series low-noise centrifugal fan is derived and expanded from YE2-DW series low-noise centrifugal fan, meeting requirements for any air flow and pressure in the design and selection of air-conditioner. The product is characterized by low noise, high efficiency, large air flow, low rotation speed, small mass etc. It includes forward type (DKF series) and backward type (DKF(H) series) which are respectively consisted of parts such as forward and backward type impellers, logarithmic spiral casing, circular arc streamline air inlet etc. Adopting fully galvanized plates, it is formed by molding with adjustable frame structure and exchangeable pulley on the right and left, making it the most ideal accessory product for industries of air-conditioner, purification, paint drying room and refrigeration.


Ⅱ Fan structure:
1. The casing is made by galvanized steel plates with weld-free seam. It is fine in appearance.
2. The forward type impeller is composed of forward multi-blade circular arc blades riveted with front and middle discs. It is made of fine machined galvanized steel plates. The backward type impeller is composed of backward arc blades fixed and welded with front and middle discs by special clamps. In order It is then calibrated through static and dynamic balance after forming, so it is smaller in vibration when in operation, excellent in pneumatic performance, low in noise and stable in operation. All the parts of impeller are formed by one-time stamping in mold to ensure its accuracy, It is then calibrated through static and dynamic balance after forming.
3. High-quality carbon structural steel is used as material of the shaft. During design, the shaft material passed the secondary verification of critical rotation speed to be high in strength, excellent in rigidity and stability.
4. Air inlet is made of mold formed galvanized steel plates. It is mounted on both sides of the fan with curved section parallel to axial direction that makes the smooth air flow and less loss.
5. Imported or domestic renowned premium bearings are used due to their reliable quality, longer service life and stable operation.
6. V-belt is used for transmission to acquire large quantity of working conditions by changing the diameter of belt pulley, so it can fully meet the requirements of air-conditioning fan for air flow and air pressure.


Ⅲ Application
1. Ventilation in buildings involving industry, civil uses, mining, tunnel, subway, etc.
2. Used along with various forms of air-conditioners and air purifier, etc.
3. Used for ventilation of various kinds of automobile spray booth and drying room, etc.
