This Daimer® exclusive technology reduces wear and tear on the pump and other components, thus prolonging the life of this highly powerful, durable electric pressure washer machine.

With one of the highest pressures (3000 psi) and flow rates (5 GPM) in its class, the 12300 AST® offers the flexibility of being used independently as a cold water pressure washer, hot water pressure washer, or steam pressure washer; offering hot temperatures up to 220º F and steam temperatures reaching 330º F. The 12300 AST® electric pressure washer offers the ability to be trailer mounted and may be purchased with optional two gun operation. This electric tri-mode pressure washer equipment is ideal for a wide array of industrial and commercial applications that would benefit from astoundingly high pressure and versatility.

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.

Powerful Pressure Wash Systems for Challenging Applications

One important aspect that determines the cleaning power of commercial pressure washers is the pressure level. In other words, gas pressure washers with moderate pressure levels are good for lighter-duty applications, while the high pressure versions are used for more challenging tasks. For this reason, cleaning professionals in industrial settings use electric pressure washers with high pressure levels.

The Super Max™ 12300 AST® available from Daimer® is a powerful and durable pressure washer that is powered by electricity, heated by propane, and includes a heavy-duty housing. These new power washers feature the unique auto shutoff technology that reduces the wear and tear on the components by automatically switching off the motor and pump when the trigger gun is not used for about 30 seconds. This tri-mode pressure washing equipment that generates cold water, hot water, or wet steam is capable of attaining pressure levels of 3000 psi and flow rates of 5 gpm.

Powered by a 10.0 HP NEMA engine, industrial pressure washers like the Super Max™ 12300 AST® generate steam at temperatures as high as 330ºF and hot water at temperatures of up to 210ºF. The heavy duty heating coils convert cold water to hot water in as little as 30 seconds. The trailer mountable configurations of these hot water pressure washers enable users to easily move the system to different spots.

If your industrial applications call for a versatile, durable and powerful pressure washer featuring exceptionally high pressure levels, then the Super Max™ 12300 AST® will be an ideal option.
