The Vac-Matic easily goes where you need it. An ergonomic design and tubeless pneumatic tires make it easy to maneuver. With our smallest vacuum footprint, it saves valuable space in your truck, too. The vacuum removal bags are made of 100% polypropylene fabric, and each expands to hold approximately 75 cubic feet, or 300 LBS, of insulation. Durable stitching keeps it all together. You can also use the bags on any vacuum with an output diameter of less than 12 inches.
