The DEWALT DWV902M Next Generation Dust Extractor is an innovative dual filter cleaning system that maintains performance during tough construction applications. It ensures constant suction power, even with the finest concrete and wood dust. Each filter is automatically cleaned every 15 seconds, reducing filter clogging and delivering constant air flow. An audible alarm alerts the user if a drop in performance occurs. The Dust extractor allows wet and dry pick up, and the variable suction control allows for the reduction of suction power if required. A built-in power take off socket allows power tool connection for automatic start and stop control when the power tool is operated. The machine continues to run for an extra 15 seconds to allow all dust to be cleared from system. For easy transportation, the Dust Extractor has a telescopic handle and large rear wheels.
