Product Description
YWFΦ300 cylindrical external rotor axial fan is composed of the wind blade,the external rotor motor, the screen cover,the lead wire and so on. The structure of the cylindrical external rotor axial fan is calculated by structural finite element, strength check, modal analysis harmonic response analysis and other methods, so the cylindrical external rotor axial fan has the advantages of stable and reliable structure, high safety factor, small vibration, strong anti-interference ability and so on. According to customer requirements, the cylindrical external rotor axial fan can be installed with thermal protectors, junction boxes and other components, or choose different installation methods such as cylinder type and box type. The blades of the cylindrical external rotor axial fan are designed according to the principles of aerodynamic laws, acoustic principles and acoustic performance requirements. The blades are twisted according to certain laws from the tip to the root of the blade. The materials are made of high-quality steel or plastic.
