The Super Max12840 AF is an industrial electric pressure washer machine that can be used independently as a cold water or hot water pressure washer and offers a higher flow rate (4 GPM) and pressure (2000 psi) than the 12820 electric powered pressure washer. The 12840 AF is powered by a 5.0 HP NEMA electric engine (230V, single phase, 60Hz is standard with other worldwide power options available-call for pricing).

Adding to the power and versatility of this powerful pressure washer machine is the included phosphatizing system. Using downstream injection, this system can pre-treat metal surfaces to prevent rust and corrosion and to prepare these surfaces for the application of paint primer or powder coating. Daimer uses only the highest quality stainless steel components to ensure the durability of this rugged pressure washer equipment.

The included stainless steel dual lance wand features a one trigger gun and two tubes, one with a high-pressure nozzle and the other with a low-pressure nozzle. The crossover valve controls the flow of water through the nozzle, but not through both at the same time.

This industrial electric pressure washer can also be ordered with either no.1 or no. 2 heating oil, diesel, or kerosene heat. Additional options include the ability to be ordered with 2-gun operation and wheeled configuration for added mobility. This model is ideal for those applications and customers that would benefit from greater performance than that offered by the 12820 AF.

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.

Road Maintenance Made Easy With Power Washer Systems

The maintenance of streets, roads, public buildings, sidewalks, and parking lots is one of the most important responsibilities of government agencies. However, the job is not an easy one. To effectively maintain vast areas of roads, public grounds, and parking lots, cleaning professionals must definitely be equipped with advanced cleaning machines, such as industrial pressure washers.

Road cleanup involves elimination of large amounts of dust, dirt, grease, and mud from roads, sidewalks, driveways, and parking areas. Commercial pressure washers eject highly pressurized hot water or cold water that helps blast off the toughest dirt buildup quickly. Using gas pressure washers takes lesser time and effort spent on road maintenance.

Pressure washer equipment that would be perfect for road maintenance applications include the Super Max™12840 AF from Daimer®. Such best electric pressure washers are capable of generating cold water or hot water at pressure levels of 2000 psi and flow rates of 4 gpm. Powered by a 5.0 HP - NEMA engine, these hot water pressure washers come with heavy-duty, schedule 80 heating coils that can convert cold water to hot water at temperatures of up to 180ºF in just 30 seconds. The hot water ejected by this pressure washer equipment helps dissolve grease, oil, and other tough deposits on roads.

Heated by diesel or kerosene, pressure washer machines, such as the Super Max™12840 AF, come with standard power option of 230V, single phase, 60Hz. However, there are other power options available for export requirements. These pressure washers also feature a powerful phosphatizing system. Optional features available with these pressure washers include wheeled configuration and two-gun operation.
