WEX250EX4 proof sidewall wind _ Heng Hing offer air conditioning fan Figure _WEX250D4 Wall

Rectangular enclosure design can be easily mounted on the concrete wall, brick wall or light steel pressure type, square rain cover solid structure, beautiful appearance. With low noise, large air volume, reliable performance, wide range of parameters, easy installation, and other characteristics, Direct drive motor, no wearing parts, maintenance-free. Reliable lubrication-free type outer rotor motor performance, reduce transmission losses and reduced weight of the machine. Since the motor is placed directly within the air stream to ensure good heat dissipation, extending the life of the fan motor is widely used in industrial and mining enterprises workshop and civilian, commercial construction projects side wall type ventilation. According to the requirements of the transmission medium can be made of corrosion, explosion-proof. EX fans are generally used for the side wall type exhaust, arranged 45 ° rain cover (or special fabricated 60 °) and insect nets (through the lights at night can prevent insect flying into the room). Wall blower can be made as the model for the WSP (WSP), arranged 90 ° rain cover (wind, rain, dust) and insect nets (through the lights at night can prevent insect flying into the workshop) WSP Wall blower with high-tech The forward-swept impeller, advanced forward swept blades using the latest aerodynamic optimization of the experimental results, the airfoil progressively cut air, curved blade smooth flowing and maintain streamlined now, when the air from the outer edge of the blade angle to reduce the from the turbulent flow, thus ensuring low noise while maximizing the amount of exhaust. Carried out during the design process of the full stress analysis, by reducing the vane tips bead amplitude to prevent blade deformation fracture, low noise external rotor or internal rotor fan professional fan motor direct-drive, effectively reducing noise on the surrounding environment Wall fan wholesale effects, square shell designed to facilitate and mounted on concrete walls, brick walls or light steel-pressure wex Wall fan model, square rain cover solid structure sidewall fan, beautiful appearance. With low noise, large air volume, reliable performance, wide range of parameters, easy installation, and other characteristics, stable and reliable machining Free-lubricated Wall fan external rotor motor performance, reduce transmission losses and reduce the weight of the machine
