Durable Materials & Construction
The US Fan Upblast Exhauster is built with a heavy-gauge aluminum housing that resists corrosion, making it perfect for outdoor, weather-exposed installations. The centrifugal backward-curved wheel is crafted from precision-balanced aluminum for smooth operation and extended motor life. A weather-resistant motor cover and rain protection system safeguard the motor and electrical components, ensuring durability in harsh environments. With its direct drive system, fewer moving parts mean less wear, longer life, and lower overall cost of ownership. Unlike standard roof ventilators, the US Fan combines the efficiency of a centrifugal fan with the convenience of a direct drive motor, eliminating the need for belts and pulleys. This design reduces energy loss, minimizes maintenance, and ensures consistent, high-performance airflow. Its upblast discharge system expels air vertically, keeping grease, fumes, and contaminants away from the roof surface and preventing damage to building materials.
