304 Stainless Steel Heavy Duty Fan

The integrated gravity shutters are constantly exposed to harsh conditions, including sunlight, rain, and high humidity. The high hardness and rust-proof nature of 304 stainless steel ensures reliable, automatic operation and structural stability.

304 stainless steel corrosion resistance is particularly crucial where the frame meets the wall, preventing premature decay and guaranteeing a longer service life for the entire unit.

Our single-stamped stainless steel blades are designed to endure extreme operational stress. They rotate at high speeds, constantly facing friction, moisture, and dust erosion. Galvanized steel sheets are softer, thinner, and break easily. While our stainless steel blades offer superior toughness, strength, and deformation resistance, which ensures powerful, stable airflow and maintains high power transmission efficiency, making it more energy-efficient.

Integrated Gravity Shutter System allows for natural ventilation without electricity once the fan stops running.

Aluminum Alloy Impeller is significantly more robust, corrosion-resistant, and durable than iron fan wheels.

This abrasion-resistant V-shaped belt ensures stable running and high power transmission efficiency.
