Characteristics and application DWEX sidewall ventilation machines using advanced forward-swept-type blades, low noise external rotor or internal rotor fan motor Direct concrete walls, brick or light steel-pressure transmission, square enclosure design can be easily installed in on the wall, square rain cover solid structure, beautiful appearance. With low noise, large air volume, reliable performance, wide range of parameters, easy installation and other characteristics, widely used in industrial enterprises workshops and residential and commercial building projects side wall type ventilation. According to the requirements of the transmission medium can be made corrosion, explosion-proof. DWEX (WEX) side wall exhaust fan for the side walls Exhaust, arranged 45 ° rain cover (or specially manufactured to 60 °) and insect nets (through the lights at night to prevent the insects flying into the workshop); may need Sidewall made blower model DWSP (WSP), arranged 90 ° Covers (wind, rain, dust) and insect nets (fly through the lights at night to prevent the insects into the shop). Optional accessories: Gravity-return valve (to ensure the workshop and outdoor isolated keep open when the fan is not), when ordering.
