Therm 1165TST 2400 PSI, 5.0 GPM

The Therm 1165TST hot water electric pressure washer, producing 2,400 PSI at 5.0 GPM, is for industrial and commercial use; perfect for the professional who need cleans within a factory or food processing plant, for use in vehicle wash bay, or on a farm, or at rental store to clean equipment returning from rental. The most effective cleaning comes from high pressure water, heat, and detergent applied all at the same time.

Equipped with the Industrial Dirt Killer turbo nozzle, that provides greatest possible cleaning impact from a pressure washer, high pressure soap, and digitally controlled heated water, the Therm is the ultimate cleaning machine.
