Introducing the 3 Speed Remote Controlled Air Filtration System by POWERTEC. This low-cost shop air filter system provides high-end results, and effectively eliminates up to 99% of airborne particulates for your workshop. This system catches and abolishes contaminants, while circulating clean air into your working area by using both, high caliber inner and outer filters. You can operate manually on the unit, or by remote control (included) to help maximize its effectiveness with the amount of time and space you're working with. Unlike some air filtration machines, this unit not only possesses the power (1/6 HP) to get the job done, but it was carefully designed to work quietly in the background, for a non-disruptive working environment. Infrared Remote Control-Allows you to control the power and set your preferred speed from across the room. Easy to Clean and Replace Dual Filter System-5 micron disposable outer filter and 1 micron easy cleaning inner filter. Energy Efficient Time Saving-Using the built-in timer, you can program the unit to automatically shut off in intervals of 1, 2, or 4 hours. Mounting Rings-Possessing a lightweight design, the well placed and constructed mounting rings (eye bolts) make ceiling installation a quick and easy task. Material: Multi Pack.
