Product Description

380V 220V industrial axial fans with External Rotor Motor for sale
YWF series external rotor fan is a new product developed by our company after repeated research and trial production by combining the advantages of technology and talents from many domestic universities. Compared with the conventional axial flow fan, the fan has the advantages of high efficiency, low noise, low vibration, compact structure, beautiful appearance, and the impeller is directly fixed on the outer circle, which makes the axial dimension shorter. A breakthrough has reached the international advanced level.

    Due to high efficiency, low noise, low vibration and short axial dimension, this series of fans can replace conventional axial fans, and can also be used in kitchens, bathrooms, industrial and mining and other occasions where oil, smoke and dust are serious.

Our Advantages

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. 

Fans housing stator and windings inside the rotor are compact, well-balanced, with widely adjustable rotation speed and good motor cooling. Built with insulation system (Class F) and integrated thermal protection. Axial fans are characterised by a series of unique properties of being quiet, robust and thermal-shielding. Useful in all those situations in a system with low pressure drop (therefore not very high resistance), the axial fans guarantee a large airflow rate.

Our plate axial fans have fixed blade impellers designed to handle large volumes of air against low resistance to flow and are designed for maximum efficiency and low noise operation. Powered by external rotor motor, the Axair range of axial fans are speed controllable by frequency or voltage. The impeller are fitted directly onto the motor for maximum efficiency and low profile compact assembly.
