Product Overview
Installed on roofs and walls. When the working medium temperature is 25℃, the relative humidity should not exceed 90%, and the dust content of the medium (including solids and impurities) should not exceed 100mg/m.³.
The fan mainly consists of an impeller, air duct, hood, motor, and other accessories. The impeller uses an axial flow fan, with a large air volume, and can also reverse airflow if needed. The hood and base are made of lightweight, high-strength, and corrosion-resistant fiberglass material, featuring an aesthetically pleasing design and resistance to wind and rain. The materials are divided into iron plate type and fiberglass type.
The main function of the roof ventilator is to provide indoor ventilation for buildings such as petroleum, chemical, light textile, metallurgy, and machinery factories, offices, laboratories, and warehouses. It can adapt to different structural forms and usage needs of buildings, and can be used for transporting corrosive gases, with performance parameters consistent with WT35-11 and WT4-72.
