What are the advantages of fiberglass reinforced plastic (FRP) fan blades?
Because metal fans are usually cut from metal sheets and bent to shape, there is a limitation in producing optimum blade profiles. On the other hand, intricate optimized computer-generated aerodynamic blade profiles can be duplicated with precision by molding fiberglass into fan blades that maximize airflow and are more efficient in power demand and airflow output. Furthermore, industrial fiberglass fan blades generally have a longer life span as they are less affected by moisture, humidity and corrosive chemicals. Over time, metal blades may corrode and rust from moisture or chemical exposure.
