CFM = 11600

HP = 3

The RCU24 3HP delivers 11,600 CFM through a 24-inch aluminum alloy upblast housing, representing a significant capacity step from the 2 HP units in the range. It is designed for large commercial buildings where a single rooftop fan must serve a shared extract riser handling multiple kitchen exhaust points, or where the smoke control strategy requires high-volume extraction from a large occupied floor area at temperatures up to 572°F.

At 11,600 CFM and 3 HP, the RCU24 3HP handles rooftop exhaust for large hotel kitchen complexes serving multiple dining outlets simultaneously, central kitchen extract in hospitals or university catering facilities, multi-tenant food court exhaust risers in commercial towers, and smoke exhaust systems in buildings where the fire strategy requires a rooftop extract rate exceeding 10,000 CFM. The 3 HP motor operating a 24-inch impeller maintains this output with headroom — it does not run at full rated load, which reduces thermal stress on the motor and extends service intervals.

The smoke fan rating at 572°F maximum working temperature is especially relevant at this capacity: smoke exhaust systems designed for large buildings typically require extract volumes well above 8,000 CFM, and the RCU24 3HP is one of the few units in the range that combines this volume with the thermal endurance required for sustained smoke extraction. Both direct drive and belt drive configurations are available, with belt drive recommended for applications where the system airflow may need to be adjusted during commissioning or seasonal operation.

For exhaust requirements between 8,300 and 11,000 CFM, the RCU20 (8,300 CFM, 2 HP) is a lower-power alternative. When the design airflow exceeds 12,000 CFM, the RCU24 5.5HP (14,000 CFM) provides the next capacity increment within the same 24-inch housing.
