Speed controls are used for manual adjustment of the fan’s performance for final system balancing or to control the fan’s output in confined spaces, such as conference or meeting rooms. The fan can be adjusted to 60% of design airflow with a speed control. This reduction in airflow and fan speed is also accompanied by a reduction in noise level.
Note: For use on direct drive fans with single phase, PSC or shaded pole motors.
