Adapter plate for attaching L-BOXXes and Tanos Systainers to the head of the vacuum cleaner. The high-performance turbine ensures strong suction power and vacuum, delivering excellent cleaning results. It maintains consistent suction power through continuous automatic filter cleaning. The flat pleated filter with nanocoating allows for optimal use of the container volume. It features a permanent socket and an electronic automatic on/off switch. The volume flow control via the rotary switch reduces the possible vacuum on the surface during intermediate and fine sanding. For wet extraction, an electronic level monitoring system is integrated. The start delay prevents voltage spikes at startup, and the shutdown delay (15 seconds after-run) clears dust residues in the suction hose. The double-walled, robust container has an integrated handle and a recessed grip for easy emptying. Dust-protected, anti-static equipment prevents static charge buildup in the suction hose.
