Ventilation
Downblast Centrifugal Fan
A downblast centrifugal roof-mounted fan is designed for efficient ventilation by expelling air downward onto the roof surface. Ideal for commercial and industrial applications, it features a robust, weather-resistant housing, backward-inclined blades for maximum air movement, and quiet operation. Typically constructed from durable materials like galvanized steel or aluminum, these fans provide reliable performance in exhausting contaminated, hot, or moist air, ensuring a safe and comfortable indoor environment.
