1High air volume and high wind pressure 2Compared with the traditional AC fan, the intersecting surface of the airfoil is relatively stable, the angle difference is small, the blade thickness is thicker, and the operation is more stable 3The air volume under the same caliber is larger, which breaks through the limitation of the frequency of the traditional AC fan and greatly increases the fan running speed. 4Stepless speed regulation, can provide 0-10V voltage speed regulation and PMW signal transmission 5Widely used in conference rooms, high-end office buildings, public places, hotels, houses, hospitals, gyms, etc.
