Remember when your workshop was full of clean air. Air-borne dust particulates can dirty up a woodworking space and harm a healthy respiratory system, but with the WEN 3-Speed Remote-Controlled Air Filtration System, you no longer need to worry. This system eradicates these contaminants by catching them in 1 of the 2 easily replaced filters while circulating the air in your work area. The powerful 3 Amp motor leaves no stone unturned, collecting every contaminant in its path. The quiet system creates 63 dB to 68 dB of noise and is controllable up to 26 ft. away with the included R.F. remote. The included eyebolts make for easy mounting and installation in a variety of wood shops. The WEN Air Filtration System collects and releases the air in your workshop after filtering it through both a 5-micron outer filter and a 1-micron inner filter. Easily switch between 3 speeds of 556, 702 and 1044 CFM depending on what your situation calls for. With the self-automated timer, you dont even have to worry about turning off your machine. Simply set the timer to automatically turn the machine off after a certain number of minutes, allowing you to easily give your workshop a thorough cleanse at the end of the day. And because this is a WEN Product, your 3-Speed Remote-Controlled Air Filtration System comes backed by a 2-year warranty, a helpful customer service support line, and a stocked inventory of replacement parts.
