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 forms a substantially continuous surface with the scrolled wall at a downstream end and with the airflow outlet at an upstream end, along the airflow path, in a first position. The blower assembly also includes an actuator for moving the scroll cut-off along a projection extending from the scrolled wall adjacent the downstream end of the scroll cut-off from the first position to a second position for reducing the airflow. The scroll cut-off may include more than one member.
