The DataVac Electric Duster 500P from Metro Vac uses a 500-Watt motor to remove dust and debris from your computer and electronic equipment so they continue to run at maximum efficiency. Unlike other electronics dusters that use compressed air, the Electric Duster 500P is a more cost effective and greener choice. It uses a powerful 500 Watt motor to blast dust, dirt, and debris rather than an aerosol can of compressed air. This item comes packed in a remailer carton.
