Product Description:

The upgraded CRW HA-300M axial exhaust fan now comes with a built-in variable speed controller, giving you full control over airflow output for maximum flexibility. Designed for commercial and industrial spaces, this 300mm ventilation fan combines performance, efficiency, and adaptability in a compact, wall-mountable unit.
