Adapter plate for securing L-BOXXes and Tanos Systainers on the head of the vacuum. The high-performance turbine ensures strong suction power and high negative pressure, enabling excellent extraction results. Consistently high suction power is maintained through continuous automatic filter cleaning. The flat pleated filter with PTFE/nanocoating allows for 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 via optical and acoustic alerts if it drops below the legal minimum value of 20 m/s. 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 during startup, and shut-off delay (15 seconds after-run) empties residual dust in the suction hose.
