Numatic RSAV200 Aircraft Backpack Vacuum Cleaner is a commercial-grade, high-capacity cleaning system specifically engineered to run directly on the standard 115V / 400Hz onboard power supplies found in aviation cabins. This lightweight rucksack vacuum features an extra-large 9-liter capacity to maximize cleaning efficiency and minimize emptying downtime on larger aircraft, all while maintaining excellent operator maneuverability in confined spaces. Built with an ergonomic, breathable mesh harness and a diffused air discharge system to ensure user comfort during long shifts, it combines heavy-duty industrial suction with an agile design to easily clean aisles, galleys, upholstery, and hard-to-reach aircraft interiors.
