Model 53 Hooded Roof Ventilator,
The HB53 hooded roof ventilator is designed for high capacity, general supply or exhaust units well-suited to applications that require the quiet and efficient movement of large volumes of air in both commercial and industrial environments. The HB53 features a pleasing, low profile design that minimizes extension above the roof line.
The HB53 utilizes a statically and dynamically balanced airfoil impeller for optimal performance and longevity. The unit’s hood is constructed of corrosive resistant fiberglass reinforced plastic and is attached to the fan with heavy structural angle supports for added stability.
