The Super Max™ 15800 AF is a powerful stationary, industrial, electric pressure washer capable of being used independently as a cold water and hot water pressure washer (up to 180°F). This powerful pressure washer machine features a lower flow rate (4 GPM) and higher pressure (2000 psi) than the 15700 AF.

Like other models in the 15000 AF series, the 15800 AF includes Daimer's downstream injection phosophatizing system for the pre-treating of metal surfaces. This powerful system combined with the power of this stationary pressure washer machine makes the 15800 AF the ideal solution for industrial facilities requiring permanent versatile pressure washer equipment with phosphatizing capabilities. Also available as an additional option is two gun operation.

The Super Max15800 AF is a stationary, electric pressure washer that offers a lower flow rate (4 GPM) but higher pressure (2000 psi) than the 15700 AF. The same heating options as other 15000 AF series models (natural gas and propane) are available on the 15800 AF.

This powerful stationary pressure washer features Daimer's exceptional phosphatizing made of the highest quality stainless steel fittings and parts. Using downstream injection, in which the chemical only comes in contact with minimal parts of the system to prevent corrosive attack, this system is ideal for pre-treating metal surfaces to prevent rust and corrosion and to prepare these surfaces for the application of paint primer or powder coating.

The Super Max 15800 AF features a stainless steel dual lance wand that has one trigger gun and two side-by-side tubes that form the lance. On the outlet of one tube is a high-pressure nozzle and the other a low-pressure nozzle. By opening and closing a crossover valve the water flow is directed through the high-pressure or the low-pressure nozzle, not both at the same time. This unit can also purchased with two gun operation. This model is ideal for those commercial/industrial applications that would benefit from having multiple operators, are involved in metallic powder coating, and/or require sandblasting capability and those that require more power than offered on the 15700 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.

Amazing Phosphatizing Functions Of Power Wash Machines

Maintenance professionals all over the world trust the cleaning action of industrial pressure washers to accomplish a host of cleaning applications in industrial settings. In addition to being powerful and durable, the best versions of commercial pressure washers also score high in terms of versatility and ease of operation. While pressure washers with mid-range pressure levels have been designed to manage moderately challenging application, you must always choose the ones with high pressure levels to tackle the tougher jobs.

The challenging jobs in industrial settings include degreasing heavy equipment, concrete maintenance, and phosphatizing metals. If you are searching for pressure washers to manage such heavy-duty cleaning tasks, you must definitely check out the Super Max™ 15800 AF available from Daimer®. Powered by a 5.0 HP NEMA engine, this pressure washer comes with a flow rate of 4 gpm and pressure level of 2000 psi. These gas pressure washers capable of generating hot water and cold water can be heated by kerosene, natural gas, propane, or diesel.

To help manage tasks, such as pre-treating metal surfaces or spot removal of paint, these hot water pressure washers feature powerful phosphatizing system comprising high-quality, stainless steel components. During the downstream injection, the chemical used for phosphatizing comes in touch with only those parts of the machine that have been designed to withstand corrosion. The presence of two nozzles, one high-pressure and another low-pressure, enables users to control the water flow through the pressure washer. The phosphatizing action of electric pressure washers, such as the Super Max™ 15800 AF, helps eliminate rust and corrosion from metal surfaces prior to applying paint or powder coating.
