Scope Of Application

WEX series sidewall (explosion-proof) axial flow ventilator also called DWEX sidewall fan (SEF for common models), which adopts advanced forward swept blade, low noise fan special motor direct drive.The square shell design can be easily installed on the concrete wall, brick wall or light steel compression wallboard, square rain cover structure is solid, beautiful appearance. Low noise, large air volume, reliable operation,With the features of low noise, large air volume, reliable operation, wide range of performance parameters, easy installation, etc., it is widely used in the workshops of factories and mining enterprises and the side-wall ventilation of civil and commercial building projects. According to the requirements of conveying medium, it can be made into
According to the requirements of conveying medium, it can be made into anticorrosive type and explosion-proof type.
WEX (SEF) series fans are generally used for side-wall ventilation, equipped with 45° rain cover (or specially manufactured to 60°) and insect-proof net (to prevent insects from flying into the workshop at night through the light). It can be made according to the requirement.
Side wall fan model WSP can be made on request, equipped with 90° rain cover (to prevent wind, rain and dust) and insect-proof net (to prevent insects from flying into the workshop at night through the light).Optional accessories: gravity check air valve commonly known as louvers (to ensure that the workshop remains isolated from the outdoors when the fan is not open), specify when ordering.
