Fein's new Turbo III Variable Speed Vacuums are designed for heavy, continuous use in industrial and professional environments. The new design included 6 wheels instead of 4 which reduced tipping. Each vacuum handles power tools with inputs of 5 to 2,000 watts. The two-stage motor offers bypass cooling which allows the engine to remain cool in the event of a filter or hose clog, ensuring long operating life. An integrated drain plug makes cleaning and emptying the vacuum an easy task.The Turbo III features an automatic On/Off switch. Simply plug the power tool of your choice into the panel-mounted outlet and the vacuum switches on simultaneously with the tool. When the power tool is shut off, the vacuum continues to run for an additional 3 seconds to clean any remaining dust trapped inside the hose.Variable suction control is a brand-new feature not previously offered on Fein vacuums. A simple switch and LED indicator control suction which allows users to run the vacuums at less capacity to improve efficiency and save money.Turbo III vacuums are powerful enough to run TWO 6-inch random orbit sanders. When coupled with Fein's premium line of dust-free tools, these vacuums achieve 98% dust-free efficiency. This is all achieved while minimizing noise levels to an absolute minimum (60dB(A) or less at 3-1/2 feet).These vacuums are ideal for carpenters, woodworkers, boat yards, fiberglass & refinishing, kitchen remodeling, tile installations, cabinet installations, and much more.
