Edge wall exhaust fans feature advanced forward sweep blades and low-noise outer or inner rotor motor direct drive, with a square housing design for easy installation on concrete walls, brick walls, or light-gauge steel plate walls. The square rainproof cover structure is sturdy and aesthetically pleasing. They boast low noise, high air volume, reliable operation, a wide range of performance parameters, and easy installation, making them widely used for edge wall ventilation and air exchange in industrial and commercial workshops, as well as civil and commercial construction projects. According to the requirements of the conveying medium, they can be made into corrosion-resistant and explosion-proof types.

Side wall exhaust fans are commonly used for side wall exhaust purposes, equipped with a 45° rain shield (or custom-made to 60°) and insect mesh (to prevent insects from flying into the workshop at night under the light). They can be customized into side wall supply fan models such as DWSP (WSP), with a 90° rain shield (protects against wind, rain, and dust) and insect mesh (to prevent insects from flying into the workshop at night under the light).
