Certified Explosion Proof Negative Pressure Exhaust Fan

Features a thickened, heat-insulated galvanized steel shell. This structure ensures the fan is sturdy, durable, rust-proof, corrosion-resistant, and high-temperature resistant—built to withstand harsh industrial conditions.

The upgraded aluminum alloy fan wheel is significantly more sturdy, durable, and corrosion-resistant compared to traditional cast iron alternatives.

The stamped U-shaped blades are designed for superior toughness, delivering powerful airflow and maximizing power efficiency.

Equipped with a pure copper core motor specifically rated for hazardous locations.
Specifications: Features IP55 protection class (dust and water jet resistant).
Performance: Ensures safe, stable operation with pure copper coils, high-grade steel sheets, and durable bearings, resulting in low temperature rise, high rotational speed, and low noise.

The gravity shutters open automatically upon fan startup and seal automatically when the fan is powered off. This hands-free operation provides excellent protection against dust, rain, and insects.

This professional system ensures the shutters open widely during operation for maximum ventilation and guarantees a superior seal when closed, improving energy efficiency.

A convenient manual pull ring allows the user to open the shutters for natural ventilation even when the exhaust fan is powered off (no electricity required).

Includes a built-in lifting handle for easy and safe movement, repositioning, and installation of the fan unit.
