To improve the anti-corrosion performance of FRP fan, can be galvanized the whole, may also produce aluminum rain hat; to solve the problem of aging glass blower, usually by increasing the thickness of fiberglass reinforced handle, which will undoubtedly increase the cost of production therefore all-glass roof glass blower steel materials cost more than all-metal structure roof fans, according to estimates, only on the difference between the cost structure of about 30%; the best way is the use of steel roof fan - FRP composite structures, rain hat and the check valve section fiberglass production. Full fiberglass excellent rust resistance and easy modeling features, according to airflow and aesthetic requirements made of a variety of different conditions glass blower, making fans of least resistance, more beautiful appearance; hairdryer and a fundamental part of the use of steel and thermally galvanized, to ensure structural strength and corrosion requirements, some connectors soldered directly to the duct, the manufacturing process is simplified.
