The Super Max8900C-840 WS is a highly powerful cold water wet sand blaster pressure washer ideal for commercial and industrial applications that would benefit from a high pressure (4000 psi) and flow rate (3.5 GPM). Powered by a 10 HP gasoline engine, the 8900C-840 has capabilities that extend beyond the contaminant removal ability of normal pressure washers. This wet sand blaster pressure washer machine actually removes a layer of material from a surface to easily remove rust, corrosion, pain, heavy deposits or other substances.

Standard on the Super Max™ 8900C-840 WS is Daimer's exceptional wet sand blaster system, comprised of only the highest quality components. The wet sandblasting system uses the metal sand point to draw sand into the system directly from a container. The 15' flexible sand pickup tube then sucks the sand into the special venturi head. In this special head the sand is mixed with high-pressure water and then exits the machine through the special round nozzle at high speeds to remove layers of material from surfaces. 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 sand flow of this powerful machine can be controlled by the proportioning valve on the head. Additionally, this wet sand blaster system can be used with a range of sand grit sizes and media, including baking soda and small plastic pellets. Wet sandblasting is safer than other methods of sandblasting, like compressed air sandblasting which requires users to wear breathing protection.

The Super Max™ 8900C-840 WS is the ideal wet sand blaster pressure washer machine for commercial and industrial applications that would benefit from extreme power, wet sandblasting capabilities and optional two gun operation.

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 Power Wash Systems With Advanced Wet Sandblasting Options For Efficient Cleaning

Industrial cleaning applications often involve challenging tasks, such as removing paint layers from metal surfaces. Usually, compressed air sandblasting is the technique used to manage such jobs. However, the process is a risky one and requires users to don protective breathing apparatus. For this reason, it would be a good idea to turn to relatively safer techniques, such as wet sandblasting. Incidentally, top suppliers now offer industrial pressure washers empowered with wet sandblasting functions.

The Super Max™ 8900C-840 WS, available from Daimer®, is an exceptionally powerful, non-heated pressure washer featuring wet sandblasting capabilities. Powered by a 10 HP gasoline engine, these gas pressure washers come with flow rates of 3.5 gpm and pressure levels of 4000 psi. The wet sandblasting function allows these high pressure washers to remove tough deposits and contaminants from various surfaces. The advanced one-and-a-half inch spray pattern makes the sandblasting feature perfect for spot removal of rust and corrosion, but not for large surfaces. In addition to sand grit of varying sizes, this wet sandblaster function in the pressure washer equipment also works with small plastic pellets and baking soda.

Electric pressure washers are not practical for use in areas where electricity supply is unreliable. In such situations, cold water based pressure washer machines, such as the Super Max™ 8900C-840 WS, will be an ideal choice. If your applications do not require the extra cleaning power of hot water pressure washers, then it makes sense to choose high-powered, non-heated versions like the Super Max™ 8900C-840 WS that score high in terms of durability, cleaning power, and wet sandblasting capabilities.
