D 780

This top-of-the-line fan delivers massive airflow to cool your extra-large spaces. Thanks to our breakthrough in motor design, the 24-foot AirVolution D-780 fan moves 346,000 cubic feet of air per minute. You may expect this massive air displacement to be a noisy event, but our gearless design makes it whisper quiet.

Its AirBrain processor adapts to your building’s input voltage, generates and seamlessly resets fault codes, and integrates into building automation systems. If the 780 is struck by an object, shaken by an earthquake, or bombarded by high winds, the fan will detect the disruption and turn off.
