Vitamix model 4500 heavy duty blender utilizes an air motor to spin up to 21000 RPM free speed.
Great for beverages, shakes, dressings, etc. Even heavy enough to grind small batches of whole grains.
Air powered appliances are an alternative for those living off the grid. Compressed air is stored in large air tanks, some the size of an LP tank. Air Compressors are powered by gasoline, diesel, motors or utilize wind and water wheel power. Without leaks at the fittings, the air tank will hold hours of use and takes only a few minutes to re-pressurize.
