The Super Max8780 WS is an electric cold water wet sand blaster pressure washer that combines portable and powerful pressure washer capabilities with the versatility of a commanding wet sand blaster system. As with all 8700 WS models, the 8780 WS is trailer mountable and can be purchased with optional two gun operation, but with a higher pressure (4000 psi) and flow rate (5 GPM) for added power.

The included wet sand blaster system extends the capabilities of this pressure washer greatly. The 8780 WS wet sand blaster pressure washer can efficiently remove rust, corrosion, paint layers, heavy deposits and other substances from a variety of surfaces. It can even restore surfaces to shiny bare metal, unlike normal pressure washers which can only remove contaminants. Adding to the versatility of this pressure washer machine is the ability to use a range of sand grit sizes and media, including baking soda and small plastic pellets for sandblasting purposes.

The Super Max™ 8780 WS uses a sand point to draw sand directly from the container and into the 15' flexible sand pickup tube which carries the sand into the special venturi head where it is mixed with high-pressure water. The mixture exits the machine through the special round nozzle and is propelled across the surface at high speeds to remove layers of substances from the surface. The sand flow can be controlled by the proportioning valve located on the head. With a specially designed 1 1/2" width spray pattern, Daimer's wet sand blaster machines work best for spot removal of corrosion, rust, and other materials from metal surfaces.

This method of sandblasting, using high-pressured water, is much safer than other forms, like compressed air sandblasting which requires the user to wear breathing protection.

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.

Sandblasting Simplified With Power Washer Systems

Sandblasting is one cleaning routine that is commonly carried out in industrial environments. To accomplish outstanding sandblasting results, users must obviously be equipped with the best industrial pressure washers. Conventional pressure washers do help eliminate contaminants from surfaces. However, when the application demands complete and efficient removal of heavy deposits, such as paint, rust and corrosion, you must turn to powerful commercial pressure washers.

The Super Max™ 8780 WS from Daimer® is a portable, cold water-based pressure washing equipment powered by a 15.0 HP NEMA engine and empowered with an efficient wet sandblasting system. It features a powder-coated steel, high gloss housing, 25 feet high pressure hydraulic hose, and durable 3 feet trigger wand with quick disconnect.

By generating flow rates of 4 gpm and high pressure levels of 4000 psi, these electric pressure washers help eliminate heavy deposits, rust, paint layers and corrosion from smaller areas on different surfaces. Unlike conventional pressure washers, this advanced pressure washing machine works well with different sizes of sand grit and varied media, such as small plastic pellets and baking soda.

The proportioning valve of this pressure washing machine enables users to control sand flow. The wet sand blasting technique of trailer mounted pressure washers, such as the Super Max™8780 WS, is relatively safer than other forms, such as compressed air sandblasting. To ensure enhanced user productivity, these truck mounted pressure washers can come with optional double-gun operation.
