Model H hooded roof fan

Model H roof fans improve air flow and make any commercial or industrial facility cooler, more comfortable, and safer. They provide general ventilation in industrial facilities such as mills, factories, and warehouses. These fans can be utilized for fresh air supply or warm air exhaust. The hood guards the opening and protects the air stream.

The Model H uses a direct drive motor. For a belt drive version, see the Model HB.
