Aermotor Windmill Company

The Aermotor Windmill Company, or Aermotor Company, is an American manufacturer of wind-powered water pumps. The widespread use of their distinctive wind pumps on ranches throughout the arid plains and deserts of the United States has made their design a quintessential image of the American West.

The company also manufactured galvanized steel fire lookout towers including a "7 x 7" model which supported a 7-by-7-foot (2.1 m × 2.1 m) steel cab at heights from 35 feet (11 m) to 175 feet (53 m). Hundreds of this model were in use in the southeastern U.S.; a dozen survived in the Northwestern U.S. in 1984.
