Wash has an Oscillating Spray Column that fans back and forth as it sprays the parts on the rotating turntable. For every rotation of the turntable the vertical spray arm oscillates 11 times creating significantly more cleaning action and increased wash water dwell time over conventional aqueous parts washers. Includes: Automatic one-hour Wash Timer for unattended operation and protection against operator neglect; 7-Day Heater Timer for pre-heating or turning off heater for energy savings when not in operation over long periods; and Low-Water Alert and Shutoff to protect heating element should the water level drop too low.
