This is the handheld electric duster that generates high-powered gusts of air to clean electronic equipment, delicate collectibles, and appliances. More powerful and longer lasting than a common dusting can of compressed air, it uses a 500-watt motor to generate a constant airflow of 70 cubic feet per minute. The duster comes with three different shaped nozzles and a detailing tool kit to safely and efficiently clear dust, dirt, and debris from keyboards, computer towers, camera lenses, sewing machines, power tools, shavers, tire rims, and the backs of televisions. AC plug with 12' cord. 7 1/2" L x 6 3/4" W x 4" H. (3 1/2 lbs.)
