High output from a compact axial blower, designed for easy use and storage without sacrificing airflow. Available as complete unit with 25’ (7.62m) of ducting and storage canister. Canister attaches to intake or output of blower for suction or ventilation. Allegro DC Blowers are designed to be used with standard car or truck batteries as the source of power. If it is necessary to leave the vehicle running to avoid draining the battery, it is important to ensure that the vehicle is parked downwind from the inlet of the blower to prevent any CO from entering the working area.
