The Super Max12820 AF is a powerful, rugged industrial pressure washer machine that can be used independently as a cold water pressure washer or hot water pressure washer. The 12820 AF offers a 3 HP NEMA (electric) engine (230V, single phase, 60Hz is standard with other worldwide power options available-call for pricing), a flow rate of 3 GPM, and a pressure 1500 psi. The 12820 AF industrial pressure washer offers customers the opportunity choose between no. 1 or no. 2 heating oil, diesel, or kerosene heating.

The Super Max 12820 AF comes standard with Daimer's outstanding, powerful 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 and powder coating. With the downstream injection method used, the chemicals contact only the injector, high-pressure hose, trigger gun, wand and nozzle, which are all comprised of stainless steel and are easy to protect against corrosive attack.

The stainless steel dual lance wand features a crossover valve that can be opened or closed to control the water flow between the high-pressure nozzle and the low-pressure nozzle, but not both at the same time.

Additionally, the phosphatizing system features the highest quality stainless steel components, further adding to the durability of this rugged pressure washer equipment. This electric powered pressure washer is ideal for those applications that require a high temperature combined with a higher flow rate and pressure. Additional options include: two gun operation and the ability to be configured with wheels for added portability if desired.

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.

Maintaining Gas Stations with Power Cleaner Machines

All commercial settings need to be maintained in impeccably good condition to impress customers with the welcoming and clean surroundings. Well-maintained premises also help boost the professional image of the business. This is applicable for gas stations as well. The heavy flow of vehicles to gas stations obviously results in the accumulation of large amount of dust, grime, mud, tar, and grease. To avoid long hours of scrubbing and washing to remove these tough deposits, you must be equipped with industrial pressure washers.

The cleaning applications in gas stations generally require the commercial pressure washing machines to remain switched on for extended periods. To survive this rough use, the gas pressure washers you choose must be solidly built from heavy-duty materials. To prevent wear and tear with daily use, the components in the electric pressure washers must be of high grade. For unmatched cleaning results in areas, such as gas stations, experts recommend purchasing heated pressure washer systems.

To experience the best of durability and efficiency in a single pressure washing equipment, check out the Super Max™ 12820 AF available from Daimer®. Such best electric pressure washers are versatile enough to eject cold water or hot water. Powered by a 3.0 HP NEMA engine, the pressure washing equipment generates a pressure level of 1500 psi and flow rate of 3 gpm. The high pressure levels combined with hot water temperatures of up to 180ºF enable the hot water pressure washers to easily dissolve and wash off tough deposits of grease, tar, and oil from the floors of gas stations. The phosphatizing system adds to the versatility of this heated pressure washer.
