HTS728 Walnut Sand Blaster give your car a new life

January 4, 2025

Walnut Blasting Guide

Carbon deposits are a common maintenance headache for many car owners and repair shops. Long-term carbon buildup can reduce engine performance, increase fuel consumption, and shorten engine service life. Traditional cleaning methods may be costly, inefficient, or difficult to apply thoroughly.AUTOOL HTS728 Walnut Sand Blaster is designed for cleaning automotive combustion chambers and air intakes. It uses finer 0.4mm-0.6mm walnut grit for more detailed cleaning and provides a practical option for workshops that need a cleaner, reusable, and more targeted carbon deposit cleaning method.

Core Selling Points

Why choose the HTS728 Walnut Sand Blaster?

1. HTS728 Provides a Targeted Solution for Engine Carbon Deposit Cleaning

The HTS728 walnut blasting machine offers a new solution for engine carbon deposit cleaning with strong performance and environmentally friendly cleaning media. Its main highlights include:

1500W powerful motor

The built-in 1500W motor provides strong suction power, helping remove stubborn carbon deposits and tiny particles hidden in narrow areas.

Natural walnut sand particles

Walnut sand particles are a natural and non-toxic cleaning medium. Compared with many chemical cleaning methods, walnut grit is more environmentally friendly and helps avoid unnecessary wear on engine parts.

Built-in filter for recycling

The built-in filter separates carbon deposits from walnut sand particles, making it easier to recycle and reuse the cleaning medium. This reduces cleaning cost and resource waste.

Dual mode selection

Recycling mode is suitable for long-term use and reduces grit waste. Filling mode improves cleaning efficiency and is suitable for faster cleaning of stubborn carbon deposits.

Pressure gauge and adjustable output

The pressure gauge allows users to adjust output pressure according to the cleaning task, from fine cleaning to stronger sandblasting.

External air compressor support

An external air compressor is required for the blasting effect. The minimum air compressor specification noted in the original article is 7kg / 0.7Mpa.

Multi-adapter design

Different adapter shapes help the machine fit a wider range of vehicles, including cars, SUVs, and other models that require intake or combustion chamber cleaning.

Product Update

Innovations and benefits of the HTS728 Walnut Sand Blaster

2. HTS728 Improves Cleaning Efficiency, Media Recycling, and Cleaning Coverage

Compared with earlier AUTOOL walnut grit cleaners, the AUTOOL HTS728 Walnut Sand Blasting Machine has been updated for more detailed engine carbon cleaning.

Eco-friendly cleaningThe finer 0.4mm-0.6mm walnut grit particles have natural eco-friendly characteristics. They can remove carbon deposits efficiently while helping protect engine parts.
Efficient cleaningCompared with some dry ice cleaning methods, walnut grit cleaners can be faster, more cost-effective, and capable of removing carbon deposits thoroughly in suitable applications.
Resource recyclingThe built-in filter separates carbon deposits and walnut sand, reducing cleaning costs and improving economic efficiency.
Flexible applicationDual-mode design and adjustable pressure make cleaning more targeted and adaptable to different service tasks.
Wider cleaning rangeThe machine can clean both air intakes and automotive combustion chambers. It can move up and down to clean the upper part of the combustion chamber, covering a broader cleaning area.

Comparison

Walnut sand cleaner vs traditional cleaning methods

3. Walnut Sand Cleaning Reduces Chemical Dependence and Supports Reusable Media

AUTOOL walnut sand cleaners have several practical advantages compared with traditional chemical cleaning methods:

Feature	Walnut Sand Cleaning Machine	Traditional Cleaning Methods
Environmental Impact	Natural, non-toxic, and eco-friendly cleaning media.	Chemicals may be harmful to the environment.
Efficiency	Strong suction supports efficient cleaning.	Cleaning time may be longer and efficiency may be lower.
Part Protection	Non-damaging cleaning helps protect components.	Chemicals or unsuitable methods may cause wear or corrosion of parts.
Cost	Reusable walnut media helps lower long-term cleaning cost.	Chemical consumables can increase operating cost.

Conclusion

4. HTS728 Helps Workshops Handle Carbon Deposits More Efficiently

Engine carbon deposits are often ignored because they are not always visible to the driver. Over time, they can affect engine efficiency and may lead to more serious problems. The HTS728 Walnut Sand Blaster provides a practical way to remove carbon deposits from suitable engine areas, especially for workshops that need a repeatable carbon cleaning process.With strong suction power, environmentally friendly walnut media, dual operating modes, adjustable pressure, and reusable grit separation, the HTS728 can help reduce long-term cleaning cost and protect engine parts during appropriate carbon deposit cleaning work.
