YWF series axial cooling fan with external rotor motor 250mm
The external rotor axial flow fan has the characteristics of compact structure, convenient installation, reliable operation, low noise, energy saving and high efficiency. The products are widely used in hotels, restaurants, industrial and mining enterprises, office buildings, theaters and other building facilities, as ancillary equipment for freezers and cold storage or for ventilation and heat dissipation. (For example, it is matched with refrigeration equipment or facilities such as supermarket freezers, ice machines, air coolers, chillers, condensing units, etc., and used with dehumidifiers, evaporators, side wall fans, fire fans, central air-conditioning fans and other equipment).
The outer rotor axial flow fan is composed of fan blades, outer rotor motor, net cover, lead wire and other parts. The structure of the fan is calculated by structural finite element, and the strength check, modal analysis, harmonic response analysis and other methods are carried out to ensure that our products have the advantages of stable and reliable structure, high safety factor, small vibration, and strong anti-interference ability! According to customer requirements, Thermal protectors, junction boxes and other components can be installed, or different installation methods such as cylinder type and box type can be selected. The blades are designed according to the principles of aerodynamics, acoustic principles and acoustic performance requirements. They are twisted according to certain rules from the tip to the root. The material is made of high-quality steel or plastic. After dynamic balance verification, it has good starting performance, stable operation and low noise.
