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.

Industrial Jobs Require High-Powered, Multi-User Power Wash Systems

The cleaning needs in industrial environments can be extremely complex and challenging. For this reason, maintenance experts always equip themselves with the best cleaning machines with proven cleaning capabilities. These experts generally use industrial pressure washers featuring the latest technologies. To help manage the most demanding industrial cleaning jobs, top suppliers now offer high pressure washers with lots of additional features and optional functions. Here is a look at one such version.

The Super Max™ 20000 AST®, available from Daimer®, is an exceptionally powerful industrial pressure washer designed for the most challenging maintenance tasks. Powered by a heavy-duty 50 HP NEMA engine, these electric pressure washers generate amazingly high pressure levels of 6500 psi and high flow rates of 8 gpm. These pressure washing machines can be subjected to long hours of use on a regular basis. During such times, the auto shut off function helps prevent overheating and wearing down of components by automatically shutting down the pump and motor, if the trigger gun is not activated for more than 30 seconds.

One of the most outstanding aspects that make the Super Max™ 20000 AST® more versatile than conventional commercial pressure washers is the ability to be configured to meet the needs of customers. This industrial pressure washer includes three remote control units and a wall-mounted NEMA 4 attachment. In other words, three users can simultaneously use these pressure washing machines. The extremely high pressure levels and multi-user function make these commercial pressure washers ideal for maintaining power plants and manufacturing facilities.
