The Super Max™ 12860 AST® ultra-powerful, oil heated fired, industrial, tri-mode electric pressure washer offers the highest flow rate (5 GPM) and pressure (3000 psi) in the 12000 AST® pressure washer series, and features the world's only, elite AST® (Automatic Shutoff Technology®). This highly beneficial function reduces the wear and tear on the pump and other components and extends the life of the 12860 AST®.

Powered by a robust 10 HP NEMA engine, this tri-mode pressure washer machine combines power with versatility, as it can be used independently as a cold water pressure washer, hot water pressure washer, and steam pressure washer. The 12860 AST® provides customers with the opportunity to choose either no.1 or no. 2 heating oil, diesel, or kerosene heating. This pressure washer machine can also be purchased with optional two gun operation equipment. Also available as trailer mountable pressure washer equipment, the Super Max™ 12860 AST® is the ultimate mobile solution for industrial facilities requiring an ultra-powerful, portable pressure washer for a wide array of demanding applications.

What is AST® Technology?

AST® is a proprietary system that works as follows: When AST® is engaged, it shuts off the pump and motor after 30 seconds if the gun is not in use and water is not flowing through the system. When the pressure washer operator pulls the trigger again, the motor and pump go on. This feature is particularly useful for applications in which the pressure washer operator is using a long hose, say more than 25 feet, and it is not practical for them to go back and forth to the machine to turn it off during every break.

The pumps and motors in conventional electric pressure washers remain active whether or not water is flowing through the system. As a result the user has to keep walking back to the system to shut it off or risk damaging the motor and pump.

Daimer offers pressure washers in a variety of power configurations for worldwide requirements. The following are available: 110-120V, 208V, 220-240V, 380V, 415V, 440-480V, and 575V; single and three phase; 50 or 60 Hz. Please contact us for pricing.

Ultra Powerful Pressure Wash Systems for Industrial Maintenance

Reputed suppliers, every now and then, keep launching new pressure washers empowered with the most advanced cleaning technologies. All these unique technologies have been developed carefully after studying the cleaning requirements in industrial and commercial settings. As a result, these innovative functions considerably enhance cleaning results, simplify the most challenging applications, and offer a host of other benefits, such as extending the life of electric pressure washers.

These gas powered pressure washers offer high pressure levels of 3000 psi and high flow rates of 5 gpm. These new pressure washers are also equipped with the unique automatic shut down technology.

These tri-mode electric power washers offer the cleaning functions of steam, cold water, and hot water power washers. Powered by a heavy-duty 10.0 HP NEMA engine and featuring powerful heating coils, commercial pressure washers, such as the Super Max™ 12860 AST®, help convert cold water to hot water in about 30 seconds. These industrial pressure washers are also available in trailer mountable configurations.
