 | Fan blade is tested by balance data, and the dynamic balance is controlled within 1g, which makes the fan run smoothly, with low vibration, low noise and enhanced stability of the whole machine. The fan blade is stamped and formed by the mold, and it is dust-free, beautiful and durable. The special blade shape design ensures large air volume without deformation or cracking. |
 | Motor have domestic brand motors and Siemens motors can be chosen. The voltage and frequency of the motor can be customized. Durable, powerful, low noise, motor protection class IP 55, insulation class F . |
 | Centrifugal opening mechanism ensures that the shutters are completely opened and closed, reducing the resistance when the shutters are opened, and increasing the flow of wind; tightly closed, can effectively block outdoor wind, light and dust from entering the room; made of high-quality nylon , ensuring the service life of the mechanism; the connection of open mechanism parts is connected with copper rivets, which is wear-resistant, does not rust, has good flexibility, and reduces the friction coefficient; |
 | Used high quality belt，to ensures the service life and maintenance-free。A and B belts are available to meet different requirements. |
 | In order to facilitate handling, the recessed plastic handles are designed on both sides of the fan body, which not only facilitates handling, but also greatly improves the transportation efficiency, and the design is reasonable, the appearance is beautiful and generous, and it does not hurt the hand and is not easy to be damaged. |
This product is widely used in livestock breeding, greenhouses, industrial and industrial plants and other places that require ventilation and cooling.
