Adapter plate for securing L-BOXXES and Tanos Systainers on the head of the vacuum cleaner. The high-performance turbine ensures strong suction power and high negative pressure, allowing for excellent dust extraction results. Consistently high suction power is maintained through continuous automatic filter cleaning. The flat pleated filter with PTFE/nanocoating enables optimal use of the container volume. Equipped with a permanent socket and electronic on/off automation. The flow sensor technology monitors the volumetric flow rate and signals any drop below the legal minimum value of 20 m/s with both optical and acoustic alerts. The volumetric flow control via the rotary switch reduces potential vacuum on the surface during paint intermediate and fine sanding. Selector switch for suction diameter to adjust the optimal volumetric flow rate. For wet extraction: with electronic level monitoring. Start delay prevents voltage spikes at startup, and the shutdown delay (15 seconds after-run) empties dust residues in the suction hose.
