Product Details
The BDW‑87‑4 FRP centrifugal roof fan is a self‑designed and self‑manufactured new product of our company. Equipped with a stepless speed‑regulating motor and elaborately made of high‑quality fiberglass‑reinforced plastic (FRP), the fan meets design requirements in both performance and noise level. It features high efficiency, low power consumption, light weight, corrosion resistance, reliable operation and easy installation. Its noise can be controlled within 70 dB(A). If further noise reduction is required, a silencer box can be installed between the foundation and the fan, which can be custom‑designed and manufactured by our company.
