Centrifugal Upblast Fans

Centrifugal Upblast Exhaust Fans are rooftop or sidewall mounted fans that are capable of handling high quantities of heat exhaust. This type of upblast fan is quieter, more efficient, and more tolerant of higher HVAC static pressures than the propeller upblast variant, but does not move the large volumes of air that the propeller upblast fan can. Centrifugal fans also have a place in restaurant applications for the removal of grease-laden exhaust (See Restaurant Grease Fans for specific models). These fans have a wide array of commercial and industrial applications, such as warehouses, hospitals, and schools.

Buy Centrifugal Upblast Fans Online

Centrifugal Upblast Fans are the gold standard for removing contaminated, grease-laden, or high-temperature air directly from a building’s interior to the outdoors. Designed for both performance and safety, these fans discharge air vertically above the roofline, ensuring that fumes, grease particles, and odors are effectively dispersed away from the building. At HVACDirect.com, we offer a wide selection of centrifugal upblast fans from trusted industry brands, providing the perfect solution for commercial kitchens, industrial plants, warehouses, and other demanding environments.

What Is a Centrifugal Upblast Fan?

A centrifugal upblast fan is the ultimate solution for powerful, reliable rooftop ventilation. Engineered with a backward-inclined or backward-curved wheel, these fans generate higher static pressure than standard propeller fans, making them perfect for ducted systems or demanding exhaust applications. They’re specifically designed to handle heavy, grease-laden air, smoke, and particulates with ease exactly what you need for busy commercial kitchens, restaurants, and industrial facilities.

With their upward air discharge, centrifugal upblast fans keep grease, odors, and contaminants away from your roof and building surfaces, ensuring a cleaner, safer environment. Many models are equipped with built-in grease collection systems, weather-resistant motor enclosures, and easy-access service panels, reducing downtime and simplifying maintenance. Every detail is crafted for long-lasting performance, even in the toughest conditions.
