The 220V DataVac Electric Duster 500 from the METRO DataVac is a compact cleaning system for computer systems. It uses a 500W motor to blow dust, dirt, and debris from computer equipment. It is a green alternative to canned air products, as it is not a throw-away item. This model is intended for use in territories requiring 220V (not for use in the US). It comes with a three-pronged European plug.
