The Super Max™ 8780 AST® is an ultra-powerful, portable, electric cold water pressure washer featuring Daimer's exclusive AST® (Automatic Shutoff Technology®). AST® extends the life of the 8780 AST® by reducing the wear and tear on the pump and other components.

Driven by a highly powerful 15 HP NEMA engine, this rugged cold water pressure washer offers extreme pressure of 4000 psi with a lower flow rate of 4 GPM. These powerful pressure washer machines can be purchased with an optional wet sandblasting system and/or two gun operation. The Super Max™ 8780 AST® is ideal for commercial and industrial applications requiring a portable cold water pressure washer with high pressure and powerful capabilities, but with a lower flow rate for less water consumption than the 8750 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, 415V, 440-480V, and 575V; single and three phase; 50 or 60 Hz. Please contact us for pricing.

Cold Water Power Wash Systems For Industrial Settings

There are a lot of heavy-duty maintenance applications in industrial settings that do not need the power of hot water pressure washers and can be satisfactorily tackled with the help of cold water-based industrial pressure washers. High pressure levels, high flow rates, and the inclusion of unique technologies endow the cold water-based gas pressure washers with extremely effective cleaning power.

The Super Max™ 8780 AST® from Daimer® is an exceptionally powerful and portable pressure washing equipment that utilizes the power of highly pressurized cold water, to offer superior cleaning results. Powered by a robust 15 HP NEMA engine, these pressure washing machines are capable of attaining flow rates of 4 gpm and pressure levels of 4000 psi. Housed in solid, powder-coated and chip-resistant steel, these electric pressure washers are durable enough to survive the rough use in industrial settings.

The auto shut off function is one notable feature in commercial pressure washers, such as the Super Max™ 8780 AST®. This function automatically shuts down the motor and pump of the pressure washing equipment, if the trigger gun is not used for more than 30 seconds and water ceases to flow through the system. As a result, the components are protected from the damaging effects of overheating.

If you are on the lookout for powerful and portable cold water pressure washers with high pressure levels and proven cleaning capabilities, then the Super Max™ 8780 AST® is perfect for your needs. These pressure washers are also available with optional wet sandblasting features and double-gun configurations.
