The Super Max™ 12200 AST® is a powerful, resourceful, propane heated, propane fired, tri-mode electric pressure washer featuring Daimer's exclusive AST® (Automatic Shutoff Technology). This feature reduces wear and tear and extends the life of the pump and other components, therefore adding durability to this high pressure (2000 psi) and high flow rate (4 GPM) pressure washer machine.

As an electric tri-mode pressure washer, the 12200 AST can be used independently as a cold pressure washer, hot water pressure washer, or steam pressure washer; offering high steam temperatures up to 330º F and hot temperatures up to 220º F. Additionally, this pressure washer equipment can be purchased with optional two gun operation. Further adding to the versatility of this machine is its trailer mounting capabilities. Thus, this electric tri-mode pressure washer is ideal for difficult industrial and commercial applications that would benefit from the high pressure, flow rate, and variable options offered.

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.

Improving User Efficiency with Power Cleaner Machines

Maintaining industrial areas is not an easy job. Cleaning professionals have to eliminate dust, dirt, grease and grime from a variety of surfaces in industrial settings. The cleaning tasks have to be completed on time and the results have to be superior. Traditional techniques, such as scrubbing, washing and wiping, are not practical in maintaining such vast areas. For this reason, cleaning experts must be empowered with the best industrial pressure washers.

The Super Max™ series of pressure washing machines available from Daimer® feature the latest in construction and technology. The Super Max™ 12200 AST® is a powerful, electric-powered and propane-heated pressure washer featuring the unique automatic shutoff function. When the trigger gun is not used for more than 30 seconds and water is no longer flowing through the system, this function of commercial pressure washers automatically shuts down the motor and pump. The pressure washers restart when the trigger gun is activated. Shutting down the high power washers when not in use prevents overheating and consequent wearing of components. This also contributes to extending the lifespan of the power wash systems. The machine has a heavy duty 5.0 HP - NEMA motor size and minimum generator size of 15000 watts.

Tri-mode gas pressure washers, such as the Super Max™ 12200 AST®, generate pressure levels of 2000 psi and flow rates of 4 gpm, to help blast off dirt buildup from hard surfaces. These electric pressure washers eject hot water at temperatures of up to 210ºF and wet steam at temperatures as high as 330ºF. To enable cleaning experts to wind up their jobs faster, these hot water pressure washers come with optional double-gun operations that guarantee improved productivity.
