The Super Max™ 12840 AST® is a powerful, mobile, industrial, tri-mode electric pressure washer that can be used independently as a cold water, hot water, or steam pressure washer. This versatile pressure washer machine features the world's only AST® (Automatic Shutoff Technology™). This exclusive technology reduces wear on this pressure washer machine and greatly extends its life.

Powered by a vigorous 5 HP NEMA engine, this powerful pressure washer offers a higher flow rate (4 GPM) at a higher pressure (2000 psi) than the 12820 AST® pressure washer equipment. The 12840 AST® also provides the customer with the opportunity to select either no.1 or no. 2 heating oil, diesel, or kerosene heating. Further adding the versatility of this machine is its trailer mountable capabilities, as well as the ability to be purchased with a optional two gun operation. The Super Max™ 12840 AST® is the ideal mobile pressure washer solution for industrial users requiring versatility and greater power than offered in the 12820 AST®.

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, 400V, 415V, 440V, 480V, and 600V; single and three phase; 50 or 60 Hz. Please contact us for pricing.
