Fiberglass Rooftop Exhaust Fan

Roof-mounted FRP fans feature a housing and an integrated base plate, both molded from fiberglass reinforced plastic (FRP) with a glass fiber content exceeding 45%. FRP offers excellent resistance to acids, alkalis, and corrosion, is non-rusting, lightweight, and long-lasting. Its design ensures convenient installation and effectively addresses common issues such as water leakage and seepage at the installation points of some fans in the market.

The fan blades are made of high-density, SMC (Sheet Molding Compound) molded FRP. Aerodynamically optimized through CFD simulation, the six large-diameter blades are designed for high air volume, scientific blade angles, and low drag coefficient. This design eliminates resonance noise typically associated with metal blade assemblies.

Equipped with a permanent magnet synchronous EC frequency-conversion motor, the fan delivers high efficiency, low temperature rise, and powerful output. An alternative option is a fully copper-wound asynchronous motor with IP55 rating for a more economical solution. The direct-drive system utilizes a rigid connection without any belt drive components, fundamentally eliminating power loss caused by belt slippage and common issues such as aging, slippage, or breakage of traditional belts. This also saves costs associated with purchasing belts and tensioners.

Inside the rain hood, a specially designed airflow guide structure optimizes air distribution. While providing protection against wind and rain, it effectively reduces vortex formation and noise generation.

A stainless-steel bracket ensures stable motor fixation, reduces vibration, effectively lowers noise, and offers enhanced sturdiness and corrosion resistance for higher safety. An FRP bracket option is also available for harsher environmental conditions.
