The Super Max 12500 GE WS is one of the most powerful machines in Daimer's line of versatile gas industrial commercial wet sand blaster pressure washers, with its robust pressure of 3000 psi and flow rate of 5 GPM and capability of being used as a cold water, hot water, and steam pressure washer with steam temperatures reaching 330ºF.

Adding to the versatility of this mobile pressure washer is its use of a powerful 18 HP gasoline engine. As such, the Super Max™ 12500 GE WS is ideal for outdoor applications requiring commanding pressure washer and sandblasting capabilities and where an electrical supply is not readily available.

Like all Super Max™ WS wet sand blaster pressure washers, the 12500 GE WS comes standard with Daimer's exceptional wet sandblasting system for the effective removal of rust, corrosion, paint layers and heavy deposits from a variety of metal surfaces, far beyond the capabilities of a standard pressure washer. For use as a wet sand blaster, this pressure washer must be used in cold water mode. Daimer's wet sandblaster machines feature a 1 1/2" width spray pattern., ideal for spot removal of corrosion, rust, and other materials from metal surfaces.

All of the parts that make up the wet sandblasting system are comprised of the highest quality components. The metal sand point draws sand into the tube directly from the container. The 15' flexible pickup tube carries the sand into the special venturi head where it mixes with high-pressure water. The mix of water and sand grit exit the head through a special round nozzle and forced at high-pressure across the surface to remove a layer for an extremely deep clean for virtually any industrial or commercial wet sandblasting applications. Additionally, users can control the flow of sand and water through the head via the proportioning valve.

The Super Max™ 12500 GE WS wet sand blaster pressure washer can also be purchased with trailer mounting and two gun operation configurations.

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 Pressure Wash Systems

To maintain professional standards and look welcoming to customers, gas stations need to be cleaned regularly. Considering the huge volume of dust, dirt, grease, road tar, and grime that vehicles bring in on a daily basis, maintaining gas stations is not an easy job. It is not practical to scrub and wash the vast areas every day. Due to the launch of advanced electric pressure washers, such challenging jobs have been simplified.

Daimer® offers you a wide range of electric pressure washers and gas pressure washers designed to manage a host of maintenance applications in commercial and industrial settings. The Super Max™ 12500 GE WS is a powerful gas pressure washer capable of attaining high flow rates of 5 gpm and high pressure levels of 3000 psi. Powered by a rugged 18 HP gasoline engine, these tri-mode industrial pressure washers feature heavy-duty 80 heating coils that help convert cold water to hot water in just 30 seconds. To help dissolve tough deposits of grease and oil, these hot water pressure washers generate hot water at temperatures ranging from 180ºF to 210ºF and steam at temperatures of up to 330º F.

The wet sandblaster system in commercial pressure washers, such as the Super Max™ 12500 GE WS, greatly enhances their cleaning capabilities. The wet sandblasting function of this gas pressure washer is especially useful when it comes to eliminating tough rust buildup from metal surfaces. The pressure washer equipment uses a mixture of sand grit and highly pressurized water to eliminate heavy paint and other substances from many surfaces at gas stations.
