WD816Walnut Shell Blasting Carbon Cleaner

Tuotteen ominaisuudet

Natural Physical Cleaning: AUTOOL WD816 uses 0.4–0.6 mm natural walnut shell particles with moderate hardness and no cleaning residue. Based on the mechanical principles of physical abrasion and high-speed impact, it efficiently removes carbon deposits from inside the engine while avoiding the risk of chemical corrosion and damage to metal components. The cleaning performance is far superior to traditional methods such as chemical cleaners and wire brushes.

Dual-Mode Blasting Gun: The AUTOOL WD816 blasting gun features two modes: Blasting and Air. Blasting mode deeply removes stubborn carbon deposits, while Air mode effectively clears residual walnut shell particles and debris, helping improve cleaning quality and prevent residue from entering the engine and causing cylinder scoring.

Powerful 1400W Motor: Equipped with a powerful 1400W motor, the AUTOOL WD816 delivers strong and stable suction. Whether removing stubborn carbon deposits or recovering walnut shell particles and debris, it provides efficient, smooth, and residue-free operation.

Efficient Recovery and Reuse: The AUTOOL WD816 features a built-in HEPA filter and filter screen that effectively separate walnut shell particles from carbon deposits during cleaning, allowing the abrasive media to be recycled and reused. This reduces waste and helps lower operating costs.

Efficient Carbon Removal: AUTOOL WD816 features a patented blasting structure with comprehensive upgrades in performance, safety, and user experience compared with conventional designs. The optimized structure provides a more concentrated spray pattern and more even coverage, making it particularly suitable for cleaning the complex combustion chamber structures of direct-injection engines.

8 Blasting Tubes: AUTOOL WD816 comes with 8 dedicated blasting tubes with different spray angles. Without extensive disassembly, the tubes can be inserted directly through the spark plug hole to reach the top of the piston, combustion chamber, intake valves, and exhaust valves for blasting. This helps avoid the risk of mechanical damage and seal failure caused by repeated disassembly and reassembly.

Multifunction Control Panel: The AUTOOL WD816 features a multifunction control panel integrating status indicators, filling mode, recovery mode, and pressure adjustment. The intuitive controls make operation simple and convenient, while adjustable pressure settings allow for more precise and safer cleaning.

Wide Vehicle Compatibility: Equipped with 23 adapters in different shapes, the AUTOOL WD816 meets the cleaning requirements of most vehicles. It is widely suitable for carbon cleaning on direct-injection and turbocharged engines from major brands such as BMW, Audi, and Mercedes-Benz, offering excellent compatibility and versatility.

TPR Silent Wheels: The rear wheels have been upgraded to TPR silent wheels for quieter, wear-resistant, and smoother movement. The machine can be easily moved alongside different vehicles for efficient carbon cleaning operations.
