Walnut Shell Sand Blaster features a 1200W motor that provides strong suction power, using physically harmless walnut shells for cleaning. It separates carbon deposits from the walnut shells through a filter, ensuring the shells are reusable. An external air compressor provides powerful sandblasting effects, effectively cleaning the intake manifold and valves, and helping the engine restore optimal performance.

Help Center

Walnut sand is made from walnut shells, which are processed through strict screening and classification after being broken. It is a walnut extract and serves as a metal polishing medium. Walnut sand has high hardness, high-pressure resistance, and wear resistance, with a microporous surface. It provides strong adsorption and sewage interception ability, and it does not cause corrosion or pollution.

Using walnut sand as an abrasive will not damage the workpiece’s surface or harm the engine when cleaning carbon deposits. The cleaning effect is remarkable, and the cost is low.

✅What Is Carbon Deposition?

Some hydrocarbon olefin residues attach to the engine intake and cylinder when the fuel does not burn completely. It residues change into a hard black shell in high-temperature conditions, called carbon deposition.

✅Why Need Clean Carbon Deposition?

Carbon deposition will decrease the air-fuel ratio, cut down engine output power, increase fuel consumption, engine drastic shake on idle status all the thing will hurt the engine deeply. So normally we should clean carbon deposition after every 40000-50000 kilometer trip.

✅Air Compressor Configuration

Air pressure up to 0.7mpa, 6bar or more air pressure.

📝Warm Tips

AUTOOL HTS518 walnut blaster is a special machine for the engine Intake pipe and intake valve back side.
Close the intake valve, then spray walnut powder into the engine intake via air pump(not included), meanwhile, HTS518 will recycle walnut powder by vacuum.
This is a closed loop. The walnut powder will impact carbon deposition on the inner wall of the intake pipe. After thousands of impacts, carbon deposition will be clear thoroughly
A chemical cleaning agent will corrode the pipe and shorten the lifetime of the engine.
Walnut powder is a pure natural polish material. It shows high performance in hardness, anti-pressure, and wear resistance.
Walnut powder hardness was lower than metal but higher than carbon deposition. Take these advantages,
AUTOOL HTS518 Walnut Shell Sand Blaster will clean the intake pipe and back side of the intake valve thoroughly but with no damage
The high-precision engine system is sensitive to the foreign matter of the intake pipe, such as the BM-W Valvetronic system.
That is why we need the AUTOOL HTS518 walnut blaster to clean the carbon deposition in the intake pipe. AUTOOL HTS518 cleans one intake pipe each time, and the 6-cylinder engine should cleaned 6 times one by one(and so on).
AUTOOL HTS518 walnut blaster is special for the intake pipe and intake valve back side clean only, if you want to clean carbon deposition on the injector/throttle valve/cylinder, please click here to shop for Injector Cleaners.
The package does not include walnut sand and a high-pressure air pump.
Walnut powder residual in the intake pipe will go to ashes at a high temperature after the engine starts.

AUTOOL HTS518 Carbona Washing Machine Cleaner Features

Features

External Air Source Design: The walnut blaster has a powerful 1400W motor and uses an external air source for continuous power. This enhances the impact force of the walnut shell abrasive, ensuring thorough removal of carbon deposits from the engine pipes.
Deep Removal of Carbon Deposits: Deeply removes the highly sticky carbon deposits on the intake manifold, intake & exhaust valves. (Solve the problems of unstable idling, insufficient fuel combustion, and reduced air-fuel ratio.)
Multiple Adapters: The AUTOOL HTS518 walnut blaster with 23 kinds of adapters, this tool is highly versatile, making it suitable for a wide range of models. For example, it works with BMW, Volkswagen, Mercedes-Benz, GM, VOLVO, NISSAN, and many more.
Integrated Design: The walnut shell sand blaster not only performs spraying and recovery simultaneously but also ensures efficient cleaning. Moreover, the filter effectively separates the walnut shell abrasive from the carbon deposits, thus allowing the abrasive to be reused. At the same time, it prevents residual particles from damaging the exhaust system at high temperatures. As a result, the cleaning process becomes both effective and safe.
Built-in Dust Filter: It can separate the recovered walnut sand grit from carbon deposits for recycling.
User-Friendly: The rear storage box is designed to store adapters, and the telescopic rod offers three adjustable height levels. Equipped with swivel casters, the unit can rotate 360°, allowing technicians to easily move the equipment during maintenance.
After- Sales Service: MRCARTOOL offers a 48 month warranty and 7×24 hour friendly customer service to ensure your shopping experience. If you have any questions about EVAP leak detectors, please contact us directly.
