AUTOOL HTS705
Product Overview
The AUTOOL HTS705 dry ice blasting machine is a compact dry ice cleaning system for automotive carbon deposit cleaning, engine bay cleaning, intake valve cleaning, throttle body cleaning, cylinder combustion chamber cleaning, and suitable workshop surface cleaning. It uses compressed air to accelerate dry ice particles toward the cleaning surface. The dry ice sublimates after impact, helping remove contaminants without water, chemical solvent, or secondary blasting media residue.
HTS705 is a professional dry ice blasting machine. Confirm the compressor, dry ice supply, shipping policy, safety protection, and cleaning requirements before ordering.
External Air Compressor Required
The air compressor is not included. HTS705 requires an external compressed air source, and cleaning effectiveness depends heavily on stable air pressure and airflow.
90 PSI / 6bar Class Air Supply
Use an air source of at least 90 PSI / 6bar class for proper cleaning. A 1.5m³/min compressor with a 300L air tank is recommended for stable operation.
Dry Ice Pellet Requirement
3mm dry ice pellets are recommended. Product materials also mention support for dry ice pellets up to 8mm, but 3mm is the standard reference for stable blasting.
Air Inlet And Nozzles
The air inlet connection is a female 1/2 thread with an inner diameter of about 19mm. Nozzle sizes are available in 5mm and 6mm.
3m Hose Included
The standard blasting hose is 3m. A longer hose can be customized up to 5m with an extra fee. Contact support before ordering a custom hose.
Shipping And Tariff Reminder
Tariff policies vary by country. HTS705 shipped from China to the United States may be tariff-free, and tariffs for other countries may be reduced depending on policy.
Return Limitation
Due to high shipping cost and possible customs duty, HTS705 does not support returns. Confirm compressor, voltage, shipping, tariff, and application details before purchase.
Use PPE And Ventilation
Dry ice is about -78.5°C. Wear gloves, goggles, hearing protection, protective clothing, and a mask. Operate in a well-ventilated area because CO₂ gas is produced.
Do Not Aim At People
Do not point the spray head at people. Dry ice particles and high-pressure airflow can cause injury. Use closed-toe shoes and avoid touching dry ice or the spray barrel directly.
Safety And Application Boundaries
Turn off the drive power of moving equipment before cleaning.
Do not operate the equipment in rain, wet locations, or unsafe electrical environments.
Keep foreign objects out of the dry ice tank when adding dry ice.
Before each operation, set ice feeding speed to 0 and check whether condensed water is sprayed from the nozzle.
Dry ice blasting is not recommended for car interiors, soft trim, or delicate surfaces unless the application is confirmed by a professional.
Dry ice can remove loose rust, surface oxidation, and weakly bonded paint, but it is not suitable for deep pitting rust, white-metal finishing, or strongly bonded coatings.

How It Works
How It Works
HTS705 uses compressed air, low-temperature dry ice, particle impact, and rapid sublimation to help separate contaminants from the surface without creating secondary blasting media waste.
Impact
Compressed air accelerates dry ice particles through the nozzle at high speed so they impact the cleaning surface and loosen contaminants.
Cold Shock
Dry ice is about -78.5°C. The thermal shock can make carbon deposits and attached dirt more brittle, helping break the bond between contaminant and substrate.
Expansion
Dry ice sublimates rapidly on impact. The solid CO₂ expands into gas, creating a micro-expansion effect that helps lift contaminants from the surface.
No Secondary Media Residue
Because dry ice turns into CO₂ gas, the process leaves no blasting media residue, reducing additional cleanup compared with many abrasive methods.
How To Choose
How To Choose
Dry ice cleaning is a physical cleaning process that can reduce disassembly, chemical residue, secondary waste, and abrasive media cleanup when used on suitable surfaces under proper conditions.
Less Disassembly
Many automotive cleaning tasks can be completed with little or no disassembly, helping reduce downtime in workshop environments.
No Chemical Solvent
Compared with chemical cleaning, dry ice blasting helps avoid chemical residue and reduces the need for solvent handling.
Less Abrasive Than Walnut Media
Unlike abrasive media such as walnut shell, dry ice does not leave solid blasting media behind and is gentler on suitable components.
Physical Carbon Removal
Dry ice cleaning removes carbon deposits through impact, cold shock, and sublimation instead of relying on combustion or chemical reaction.
Applications

Connect the machine and accessories properly, check whether parts are loose, and remove unnecessary items from the machine body and work area.
Test Before Adding Dry Ice
Turn on the power switch, start the machine, press the handle switch, and adjust dry ice volume from 0 to maximum to check whether there is any abnormality before trial operation.
Add Dry Ice And Adjust Output
Add an appropriate volume of dry ice and close the lid. Start around setting 5, then adjust according to cleaning effect. For smaller inner diameter barrels, start around setting 3.
Start Cleaning
Align the spray gun with the part to be cleaned and press the handle switch to begin cleaning. Keep the nozzle away from people and sensitive surfaces.
Finish And Clear Residue
After cleaning, set dry ice output to 0 and run the spray gun for 30-50 seconds to clear remaining dry ice from the feeding pipe. Then turn off power, disconnect air, and store accessories.
Use Notes
Cleaning time and dry ice consumption depend on carbon buildup, cleaning area, air pressure, airflow, dry ice quality, and nozzle choice.
The product image shows reference values: four cylinders about 5-10 minutes with 3-5kg dry ice; intake port about 5-10 minutes with 4-6kg dry ice.
Do not shut down immediately while residual dry ice remains in the hose, or ice blockage may occur.
If the machine is suspended before finishing, set ice feeding speed to 0 and spray for 30-50 seconds to discharge residual ice.
Product Details
Product Details
Use these checks to reduce ice blockage, poor cleaning results, hose wear, moisture problems, and storage damage.
Keep Air Clean And Dry
If the dry ice pipe leaks ice and air or the cleaning effect is weak, check whether the compressed air supplied to the blaster is free of oil and water.
Prevent Ice Blocking
Before pausing or stopping, set ice output to 0 and keep spraying briefly to discharge residual ice from the pipe and reduce freezing inside the hose.
Check Air Pressure And Flow
If carbon deposits or tough stains are not cleaned thoroughly, first check whether external air pressure and flow are insufficient or restricted by a thin or long air supply pipe.
Inspect Wear Parts
Dry ice rubbing against the pipe wall over long use can thin the hose. Contact support if the dry ice pipe needs replacement.
Tighten Loose Parts
Regularly check parts that need tightening or connection. Tighten loose parts promptly to support safe operation.

Questions And Answers
These answers cover air compressor requirements, dry ice pellets, safety, working principle, cleaning applications, model differences, paint and rust limitations, troubleshooting, accessories, return policy, warranty, and support.
HTS705 requires an external air compressor, which is not included. It is recommended to use at least a 90 PSI / 6bar class air source. For stable operation, use a 1.5m³/min compressor with a 300L air tank. If the cleaning effect is weak, first check whether the air pressure and airflow are sufficient and whether the air supply pipe is too thin, too long, or causing pressure loss.
3mm dry ice pellets are recommended for HTS705. The warm tips also mention that up to 8mm dry ice pellets can be used. For most automotive carbon cleaning tasks, 3mm pellets are the safer standard recommendation for more stable delivery and better control.
You need the HTS705 machine, a suitable external compressed air source, grounded power supply, dry ice supply, blasting hose, spray accessories, nozzles, and proper PPE. The only major external items required for operation are compressed air, power, and dry ice. If using a portable diesel compressor, an aftercooler may help remove moisture depending on humidity.
Dry ice blasting works through impact, cold shock, and expansion. Compressed air accelerates dry ice particles toward the surface. The low temperature makes contaminants brittle, and the dry ice rapidly sublimates into CO₂ gas on impact, helping lift contaminants away without leaving secondary blasting media residue.
HTS705 is suitable for automotive carbon deposit cleaning in areas such as engine bays, cylinder combustion chambers, intake valves, throttle bodies, engine components, wheel hubs, and underbody parts when the surface and application are appropriate. It is not recommended for car interiors, soft trim, or delicate surfaces unless confirmed by a professional.
Dry ice consumption varies by carbon buildup, cleaning area, air supply, and operator technique. The product image gives reference examples: four cylinders may take about 5-10 minutes and 3-5kg dry ice, while intake port cleaning may take about 5-10 minutes and 4-6kg dry ice. Treat these as references, not fixed guarantees.
Dry ice sublimates on impact, so it does not leave secondary blasting media residue, water, or chemical solvent. The removed dirt or carbon deposits still need to be cleared from the work area.
Wear gloves, goggles, hearing protection, protective clothing, a mask, and closed-toe shoes. Dry ice is about -78.5°C and can cause cold burns. Operate in a well-ventilated area because CO₂ gas is produced. Do not aim the spray head at people. Turn off moving equipment before cleaning, and do not operate the machine in wet areas or rain.
Dry ice blasting can remove failing paint or weakly bonded paint in some applications, but it is a mild to medium cleaning method. Strongly bonded paint, certain primers, or coatings with high adhesion may be too slow, too mild, or ineffective for dry ice alone.
Dry ice blasting can remove loosely adhered rust, surface rust, oxidation, and salt residue. It will not remove deeply adhered rust, pitting oxidation, or create a contoured / white-metal finish because dry ice is non-abrasive.
Dry ice blasting may be used in professional mold remediation workflows under applicable standards, ventilation, containment, and PPE requirements. HTS705 is primarily positioned here for automotive and workshop cleaning, so mold remediation should be evaluated by a qualified professional before use.
HTS705 is the basic portable model with 5kg dry ice capacity, single pressure gauge, and compact body. HTS708 increases capacity to 7.5kg and is better for daily professional workshop use. HTS709 also has 7.5kg capacity but adds dual pressure gauges and more advanced control for complex or precision cleaning tasks.
Dry ice cleaning is a physical cleaning process. It does not require chemical solvents, does not leave walnut shell media behind, and can reduce disassembly in suitable applications. Compared with abrasive media, dry ice is less abrasive on suitable components, but it also has limits for strong coatings, deep rust, or surfaces that require abrasive finishing.
If carbon deposits or tough stains are not cleaned thoroughly, first check whether the external air pressure and airflow are insufficient. Use at least 6bar working pressure and at least 1m³/min flow. If the air supply pipe is too thin, too long, or directly connected through a restrictive quick connector, pressure drop may reduce cleaning performance. Consider connecting the blaster to the main air supply pipe when appropriate.
This may be internal ice blockage caused by intermittent use or immediate shutdown while residual dry ice remains in the outlet pipe. First adjust the ice discharge volume to 0, turn on the spray gun switch, and keep the machine running for about 3 minutes. Then adjust ice discharge volume to about 20%-30% and check whether ice output recovers.
Stop operation and open the cover plate to check whether there is too much dry ice. If there is too much, remove part of the dry ice and continue. Check whether the vibration pump works. When dry ice is filled into the funnel, it may instantly cool the air and form condensed caking; the steel bar at the center of the funnel may need to be moved up and down manually.
Check whether the compressed air supplied to the dry ice blaster is free of oil and water. If the dry ice pipe has been used for a long time, dry ice may wear and thin the internal pipe wall. Contact AUTOOL support if the pipe may need replacement.
Refer to the Packing List image for the final package contents. The package includes the HTS705 main unit and accessories such as intake hose, ice outlet pipe with signal line and switch, rotatable ice spray handle, ice spray barrel, ice shovel, fuses, ground clip wire, ground wire connector, safety goggles, gloves, earplugs, user manual, and certificate.
HTS705 does not support returns because it has relatively high shipping cost and may involve customs duty. Contact AUTOOL Store before ordering if you need to confirm compressor requirements, voltage, dry ice supply, tariffs, shipping details, application suitability, or model selection.
AUTOOL provides 3-year warranty support for eligible non-human damage cases. Repair, replacement parts, and service handling depend on the actual issue and warranty policy. For setup, troubleshooting, accessories, hose replacement, or machine support, contact AUTOOL Store.
