The AD-24 is a small footprint model with permanently lubricated bearings on the motor and drive system. It uses V-belts and pulleys for smooth, quiet, and trouble free operation. The cabinet is electrostatically powder-painted inside and out then baked at 420-degrees Fahrenheit before final assembly – ensuring the hardest surface and the longest lasting finish in the industry. The AD-24 also features a steel door with gasket-less glass and an easy-to-read LCD screen with a friendly multilingual interface.
