Rexair LLC is an American manufacturer of home cleaning systems based in Troy, Michigan. Rexair is predominantly known for its production and marketing of a home cleaning system that uses water as its primary filter. Along with its corporate headquarters in Troy, Rexair also has a manufacturing facility in Cadillac, Michigan. In the early 1920s, John W. Newcombe invented a device that separated dust and particulates from the air. He called his new invention the "Newcombe Separator". The Newcombe Separator has a cup-shaped part at its center that spins at high speed, creating centrifugal force. Air can be pulled through holes in the separator, while anything with weight is effectively thrown outward from the separator, trapping it in the bottom of the machine. This air-cleaning device led to changes in the method of collecting dust and contaminants from the home and workplace. More information...
