THe DataVac line has been completely redesigned from the ground-up. It is much more compact and comfortable to use than previous models and features a new, almost unbelievably powerful 500-Watt motor that literally blasts dust, dirt and debris off expensive computer/electronic equipment to keep it running at peak efficiency. The DataVac; Electric Duster is positioned as a "greener", more effective and cost-efficient alternative to the controversial "canned air" products currently dominating the category.
