A blower assembly includes a housing having a scrolled wall, a motor having an output shaft extending within the housing, an impeller positioned within the housing and mounted to the output shaft for creating an airflow along an airflow path within the housing, an airflow outlet, and a scroll cut-off. The scroll cut-off may rotate about its central or center axis and forms a substantially continuous surface with the scrolled wall and with the airflow outlet, along the airflow path, in a first position and defines an air gap. The blower assembly also includes an actuator for rotating the scroll cut-off from the first position to a second position wherein the air gap is increased for reducing the airflow.
