The Super Max8900C-640 WS is a gasoline-powered, cold water wet sand blaster pressure washer with a higher pressure (3000 psi) but lower flow rate (3.5 GPM) than the 8900C-525 WS, but with the same powerful wet sandblasting functionality and trailer mounting capability. For applications requiring heat, it can accept hot water up to 180°F. The 8900C-525 can remove rust, corrosion, paint layers, heavy deposits and more from surfaces by actually removing layers of material from these surfaces with high-pressured water and sand grit.

Powered by a 10 HP gasoline engine, the Super Max8900C-640 WS is a portable cold water wet sand blaster pressure washer that provides a higher pressure of 3000 psi and lower flow rate of 3.5 GPM than the 8900C-525 WS. This pressure washer machine has the ability to actually remove layers of material (like rust, corrosion, paint layers, heavy deposits and more) from surfaces. It can restore surfaces back to shiny bare metal.

The wet sand blaster system forces high-pressure water carrying sand grit across surfaces at high speeds to remove a layer of material. The 8900C-640 WS does so through the combined efforts of its various parts comprised of only the highest quality components. These parts included the metal sand point, 15' flexible sand pickup tube, the special venturi head and the proportioning valve for the control of sand flow.

Wet sandblasting is the safest and most efficient method of sandblasting. It does not require the user to wear breathing protection, while compressed air sandblasting does. Wet sandblasting is ideal for small area spot cleaning and layer removal, as it is slower than dry blasting. 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.

The Super Max™ 8900C-640 WC is the ideal machine for a wide array of pressure washer applications that require the combination of power, portability and wet sandblasting capabilities. This wet sand blaster pressure washer machine can be purchased with optional two-gun operation and is trailer mountable when the wheels are removed.

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.

Wet Sandblaster Functions In Power Wash Machines

Sandblasting is just one among the many industrial applications that cleaning experts have to tackle on a routine basis. It, therefore, makes sense to choose the safest and most efficient industrial pressure washers to manage the job. Experts agree that wet sandblasting is an ideal sandblasting technique, since it is slower than dry sandblasting and perfect for spot cleaning. Wet sandblasting also does not require users to wear protective breathing gear unlike the case of compressed air sandblasting. Here is a look at commercial pressure washers and high pressure washers empowered with wet sandblasting functions.

Daimer® offers you the Super Max™ 8900C-640 WS, a non-heated and portable commercial pressure washer featuring a powerful wet sandblaster function. Powered by a heavy-duty 10 HP gasoline engine, these pressure washing machines generate flow rates of 4 gpm and pressure levels of 3000 psi to efficiently spot clean rust, paint, and corrosion from surfaces with its 1/2" spray pattern. The powder-coated, steel housing adds to the durability of these high pressure washers. Unlike electric pressure washers, these fuel-powered versions are not dependent on the availability of electricity.

The wet sandblasting function in trailer mounted pressure washers, such as the Super Max™ 8900C-640 WS, works by forcing highly pressurized water containing sand grit at high speed across different surfaces. To continue functioning in top condition without incurring any maintenance issues, all components in the wet sandblasting system of the industrial pressure washers are comprised of high-quality materials. The main parts of this commercial pressure washer included in wet sandblasting are the metal sand point, the sand pick-up tube, the venturi head and the valve that controls the flow of the sand.
