Remember when your workshop was full of clean air? Air-borne wood particulates can dirty up workspaces and seriously harm a respiratory system. The WEN 3-Speed Remote-Controlled Air Filtration System eradicates these contaminants by catching them in one of the two easily cleanable filters while circulating the air in your work area. The quiet system is controllable from up to 26 feet away via the included remote. The lightweight design weighs in at a mere 31 pounds with hooks for easy installation to any ceiling. Easily switch between three speeds of 300, 350 and 400 CFM depending on what the situation calls for. With the time feature, you don't even have to worry about turning off your machine. Just set the timer. The machine will turn off on its own once the time runs out, allowing you to give your workshop a thorough cleanse at the end of a day of woodworking without having to be present.
