The Super Max™ 15500 AST® is a versatile, stationary, industrial/commercial, electric tri-mode pressure washer that can function individually as a cold water pressure washer, hot water pressure washer, and steam pressure washer; with hot water temperatures reaching 220ºF and steam temperatures up to 330ºF. Most importantly, this pressure washer machine features Daimer's exclusive AST® (Automatic Shutoff Technology®). The only technology of its kind in the global market, these pressure washer machines feature an automatic control that reduces the wear and tear on the pump and other components, as well as greatly extending the life of the 15500 AST® electric pressure washer.

The 15500 AST® features a heavy duty 3 HP NEMA engine to provide a higher flow rate (4 GPM) and pressure (1000 psi), with the same available heating options as all 15000 AST® series pressure washer machines. Available options include: two gun operation. The Super Max® 15500 AST® pressure washer machine is the ideal solution for industrial/commercial applications requiring a permanent pressure washer addition with a high flow rate and mid-range pressure.

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.

Unique Technologies in Advanced Power Cleaner Systems

When it comes to industrial maintenance jobs, cleaning experts trust the capabilities of the best pressure cleaners. In addition to high pressure levels and flow rates, these industrial pressure washers feature lots of advanced functions that help enhance the cleaning capabilities. To experience the latest in pressure cleaning technologies, remember to purchase pressure washers only from top suppliers.

The Super Max™ 15500 AST® from Daimer® is a stationary version of pressure washer machine featuring flow rates of 4 gpm and pressure levels of 1000 psi. Powered by 3 HP - NEMA engine, these gas pressure washers are empowered with advanced features, such as:

  • Heating options: Electric pressure washers, such as the Super Max™ 15500 AST®, are powered by electricity and heated by fuels. The heating methods include diesel, propane, natural gas, or kerosene.
  • Reduction of wear and tear: To ensure that the steam pressure washers continue functioning at their best, the components in it must be protected from overheating and consequent wearing. For this reason, the Super Max™ 15500 AST® comes with an auto shut off function. When the trigger gun is not in use for 30 seconds, this technology helps automatically shut down the system and prevent overheating. In the long run, this technology extends the lifespan of electric pressure washers.
  • Chemical infusion: Sometimes, cleaning experts may need to boost the action of pressure washers. The high pressure chemical injection allows users to add chemicals to the system.
  • These pressure cleaners are tri-mode, capable of ejecting cold water, steam, and hot water to manage varied cleaning applications.
