Sandia 20-3001 Raven HEPA 10 qt Backpack Vacuum Standard Kit Sandia’s Raven vacuums deliver the latest advances in vacuum design technology to give you the clear-cut advantage. Raven’s third major design enhancement in as many years clearly demonstrates Sandia’s commitment to design excellence and powerful performance. Take a closer look, and you’ll see that never before have so many advanced features been incorporated into a compact, backpack design. As debris settles to the bottom of the vacuum bag, the cloth bag sags and contacts the motor-filter, reducing airflow. The Improvement... The Raven’s new deflector plate holds the heavy debris away from the motor filter during use. As the bag continues to fill it bulges to the sides contacting the cylindrical body. Airflow is severely reduced. The Improvement... The Raven abandoned the cylindrical body and tapered the vacuum-body 3/4” per side to allow air-flow around the bulging bag. Excessive motor noise. Carbon brushes on the motor create the majority of motor noise. The Improvement... The Raven added 70 inches of sound deadening waffle foam materials to make the Raven the quietest vacuum in its category. Exclusive 5-year Warranty. Static Dissipating Vacuum hose. Angled Hose Keeps the hose from hitting you in the head. Threaded Cap Eliminates separation of the cap and hose. Stainless Steel Clamps Eliminate slippery, hard-to-close screw tops. Vacuum Bag Deflector Keeps particles from tearing the vacuum bag. Kimberly Clark’s Finest Vacuum Cloth lasts for years, and it’s washable (air dry only). New, Improved Microbag Uses heavy-duty paper to last longer and stay stronger under heavy use. Bag Support Plate (Patent Pending) Keeps sagging, heavy bags from impeding air flow.
