Model H series – Roof Fan

BENEFITS

Model H roof fans improve air flow and make any commercial or industrial facility cooler, more comfortable, and safer. The hood guards the opening and protects the air stream.

The powerful TEFC motor provides trouble-free operation. Direct or belt drive models are available.

• Model H uses a direct drive motor, which has no belts to replace or pulleys to adjust for simplified operation.
• Model HB uses a belt drive motor, which includes a variable pitch drive for precise speed control and quieter operation.

All models 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. Supply fans can be fitted with an internal filter on the hood to limit foreign material from entering the building.
