The Super Max15900 AF is the most powerful pressure washer in the 15000 AF series. This stationary, electric pressure washer offers the same features and heating options (natural gas or propane) as the other 15000 PH series models, but with a higher flow rate (5 GPM) and pressure (3000psi).

Featured on this highly powerful pressure washer machine is Daimer's outstanding phosphatizing system for the pre-treating of metal surfaces to prevent rust and corrosion and to prepare these surfaces for the application of paint primer or powder coating. This powerful phosphatizing system uses downstream injection, the most common method in which the chemical only contacts the injector, high-pressure hose, trigger gun, wand and nozzle, which are all easy to protect against corrosive attack. This method combined with Daimer's high quality stainless steel fittings and parts make this pressure washer machine and its corresponding phosphatizing system highly durable solutions for an array of industrial applications.

The included stainless steel dual lance wand features a high-pressure nozzle at the outlet of one tube and a low-pressure nozzle at the outlet of the other tube that make up the lance. Opening and closing the crossover valve directs the flow of water through either nozzle, but not both at the same time.

Two gun operation is available on the Super Max™ 15900 AF. The Super Max™ 15900 AF is ideal for industrial applications that require the permanent addition of a powerful, versatile electric pressure washer for difficult cleaning applications and those that require wet sandblasting capability or phosphatizing capability, especially those involved in metallic powder coating.

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.

Use Of Powerful Phosphatizing Function In Pressure Wash Systems

There are plenty of highly challenging and extremely difficult cleaning applications in industrial settings that require the use of pressure washing machines with high pressure levels. Pressure cleaners that offer the unmatched combination of high pressure levels and high flow rates are able to accomplish superior cleaning results, as compared to pressure wash systems with mid-range pressure levels.

Cleaning metal surfaces is one of the most demanding tasks in industrial settings that maintenance professionals have to manage with the help of pressure cleaners. The rust, paint, and corrosion on metal surfaces have to be efficiently removed using commercial pressure washers with extremely high pressure levels. For this reason, leading suppliers now offer a wide range of electric pressure washers featuring pressure levels above 3000 psi. To ensure maximum efficiency, most of these industrial pressure washers are available with optional two-gun configurations.

The Super Max™ 15900 AF from Daimer® is an extremely powerful pressure cleaner featuring a pressure level of 3000 psi and flow rate of 5 gpm. Powered by a 10.0 HP NEMA engine, the stationary pressure cleaner heated by diesel, natural gas, or propane, generates cold water or hot water according to your needs. Such gas pressure washers are fortified with a powerful phosphatizing system that offers outstanding results in pre-treating metal surfaces. When metals have to be prepared for the application of powder-coating or paint primer, the phosphatizing function is the final step prior to painting. These hot water pressure washers utilize downstream injection method that guarantees the best phosphatizing results.
