Product Features

Large-Diameter Aerodynamic Fan Blades:

Crafted from aluminum alloy or stainless steel with multi-blade designs. Optimized through advanced fluid dynamics, they deliver high air pressure and long-distance exhaust, allowing for rapid indoor and outdoor air replacement.

Full Metal Safety Grille & Automatic Louvers:

The front is covered by a high-strength square-mesh metal protective grille, effectively preventing foreign objects from entering and protecting operators from accidental contact. The rear is equipped with standard automatic gravity louvers. These louvers automatically open when the fan operates and close by gravity when it stops, providing excellent rain, dust, and bird protection.

Made from high-standard galvanized steel or premium stainless steel via precision bending and welding. The thickened frame ensures robust structural stability. The surface is treated for UV, acid, and alkali resistance, making it exceptionally suitable for harsh, humid, dusty, or mildly corrosive environments such as livestock farms and chemical facilities.

Easy Wall-Mounting & Low-Maintenance Design:

The square exterior is designed with standard mounting flanges for simple installation on brick or corrugated steel walls. The modular structure allows for effortless routine cleaning and belt replacements, ensuring extremely low after-sales maintenance costs.
