AUTOOL HTS558 Walnut Blaster Engine Cleaner

Manufacturers produce walnut sand by breaking walnut shells and then strictly screening and classifying them. 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.

The walnut shell abrasive size should be between 0.6~1.2 mm. Under normal conditions, users can reuse walnut shell abrasive 5 to 10 times.

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.

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

We recommend using an air compressor equipped with a dryer filter to effectively prevent moisture buildup, which can cause walnut shell media to clump and result in poor blasting performance.

A walnut shell sand blaster is a specialized tool used to clean the intake and valves of an automobile engine using crushed walnut shells, also known as walnut media, as the abrasive material. It is commonly used in automotive maintenance to remove carbon deposits that cause engine problems if left untreated.

The walnut blasting machine uses compressed air to shoot crushed walnut shells through a nozzle at high speed. The shells hit the surface of engine parts and remove carbon buildup. As they blast, the shells break into small pieces. This makes them a gentle and effective abrasive for cleaning delicate engine components.

Yes, walnut blasting is a safe and effective way to clean intake and valves on gasoline and diesel engines. Removing the valve cover is important to access the engine parts and clean them properly. However, it’s best to consult a professional before using the machine on your specific vehicle.

Walnut blasting is usually safe, but there are risks if it’s not done properly. Using the correct method helps fix engine problems like hard starts and improves engine performance.

The main risk is breathing in fine walnut shell dust. This can cause breathing problems if you don’t use safety gear. When using the machine, always wear a respirator and goggles to stay protected.

How often you should clean the intake and valves depends on factors like the vehicle’s age, mileage, and driving habits. Generally, it’s recommended to clean them every 30,000-50,000 miles or when you notice a drop in engine performance. However, it’s best to consult a professional mechanic for personalized recommendations based on your vehicle.

Yes, you can easily find replacement parts and blasting media for walnut blasting machines. You can buy them from the AUTOOL.
