Available as blower only or complete unit with 15 (4.57 m) or 25 (7.62 m) of ducting, storage canister and alligator clips. 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.
