The Super Max™ 12800 is a mobile, commercial/industrial, tri-mode electric pressure washer that can be used individually as a cold water pressure washer, hot water pressure washer, or steam pressure washer. This versatile electric pressure washer machine features the world's only, elite AST® (Automatic Shutoff Technology ). This exclusive, beneficial function reduces the wear on the pump and other components, thus extending the life of the 12800 AST®.

This multi-faceted pressure washer equipment is powered by a 1.5 HP NEMA engine, offering a flow rate of 2 GPM at a pressure level of 1000 psi; making the Super Max® 12800 AST® ideal for a variety of commercial/industrial applications requiring a durable, mobile, comprehensive electric pressure washer machine with moderate power. Additionally, the 12800 AST® offers users the option of choosing no. 1 or no. 2 heating oil, diesel, or kerosene heating. Adding to the versatility of these tri-mode pressure washer machines are their trailer mounting capabilities and the ability to be purchased with additional two gun operation.

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.

Experience the Incredible Power of Pressure Wash Systems

If your maintenance professionals are having a hard time maintaining industrial premises well, then it is high time you introduced them to the incredible cleaning action of industrial pressure washers. Traditional cleaning methods involve eliminating dust and other loose particulate matter from surfaces before using chemicals to dissolve tough dirt buildup. The surfaces will then be scrubbed to completely remove the deposits. The chemicals and other debris will then be washed away with water from a hose line. Obviously, the entire process demands a plenty of time and tremendous effort. For this reason, it will be a great idea to switch to advanced hard surface cleaners, such as high power washers.

The Super Max™ series of pressure washer equipment available from Daimer® are renowned for their durability, efficiency, and ease of operation. For instance, the Super Max™ 12800AST is a high-powered pressure washer notable for its high pressure levels, flow rates, and unique technologies. Pressure levels of 1000 psi and flow rates of 2 gpm endow these hard surface cleaners with unmatched cleaning efficiency.

Tri-mode capabilities of electric pressure washers, such as the Super Max™ 12800AST, enable users to experience the benefits of wet steam, cold water, and hot water pressure washers. To easily dissolve the toughest dirt buildup on different surfaces, these gas pressure washers eject hot water at temperatures ranging from 180ºF to 210ºF and steam at temperatures of up to 330ºF. Powered by a heavy-duty 1.5 HP - NEMA engine, this trailer mounted pressure washer also features two-gun configurations, a 50 feet high pressure steam hose, and a durable 3 feet trigger wand with quick disconnect for added efficiency.
