AUTOOL HTS708 · 7.5 kg Mobile Dry Ice Blaster
Clean Longer Between Dry Ice Refills
Clean suitable automotive and industrial surfaces without water or chemical solvent using this dry ice blaster. The 7.5 kg hopper supports repeated work between refills, while adjustable ice delivery and a 3 m hose help tune output and reach around the bay. Air treatment helps reduce moisture-related clumping. External compressed air and a local dry ice supply are required; loosened contamination still needs collection.

Key Features
A 7.5 kg Hopper with Mobile Workshop Hardware
7.5 kg Workshop Capacity
The 7.5 kg dry ice tank extends cleaning time between refills during repeated workshop use.
Adjustable Dry Ice Delivery
The control panel supports dry ice amount adjustment, allowing the operator to adjust cleaning intensity for different tasks. Set output for the tested cleaning task rather than using one intensity on every surface.
Dry Physical Cleaning
Dry ice blasting removes suitable contamination without water or chemical solvents and sublimates after impact, helping avoid blast-media or chemical residue on cleaned parts.
Mobile Workshop Body
Dedicated air-source and blasting-gun connections, a pull handle, casters, and a 3 m hose support setup, movement, and reach around the workshop bay.
Air Filtration and Dry-Air Setup
Compressed air accelerates dry ice particles through the blasting hose and nozzle toward the surface being cleaned. Air treatment helps reduce moisture-related dry ice clumping and feed interruption.
Automotive and Industrial Cleaning
Use on suitable automotive and industrial surfaces only after confirming material, coating and access.
Residue-Free Media
The dry ice becomes gas after impact, so no dry ice particles remain. Removed dirt or carbon deposits still need to be collected or cleaned away.
Sublimation Expansion
Upon impact, dry ice rapidly sublimates into CO₂ gas and expands in volume, creating a micro-explosion effect that helps lift contaminants.
Low-Temperature Impact
Dry ice at about -78.5°C creates a thermal shock effect that helps make deposits brittle and loosen the bond to the surface.
Air Inlet Connection
The air inlet is a female 1/2 thread with an inner diameter of about 19 mm.
3 Years Warranty Support
Main unit: 3-year warranty. Standard accessories: 1-year warranty. Warranty Policy.
Safety & Compatibility
Ventilate CO₂ and Verify Air, Power, and Surface
Compressed Air
The external compressor is not included. Confirm at least 90 psi and dynamic flow, with 1.5 m³/min and a 300 L tank recommended.
Dry Ice and Ventilation
Avoid skin contact, use cold/eye/hearing protection and ventilate for CO₂.
Material and Coating Test
Do not promise no damage to paint, rubber, plastics, labels or aged coatings; test first.
Grounded Power Version
Confirm voltage, plug, phase and protective earth before purchase/use.
Feed-Path Clearing
Use dry air and clear residual pellets to reduce clumping and blockage.
Wear Full Protective Equipment
Wear protective goggles, ear protection, work clothes, gloves, and closed-toe protective shoes when operating the dry ice blaster.
Check Condensate Before Work
Before work, set the ice feed speed to 0 and check whether condensate is blasted out of the nozzle.
Purge Residual Dry Ice
After dry ice blasting, adjust dry ice flow to 0 and run the blasting gun for about 30 seconds to clear dry ice from the tray and tube.
Keep Tank Free of Debris
Keep the dry ice tank clean when adding dry ice. Do not allow foreign objects to fall into the equipment.
CO₂ Ventilation
HTS708 uses solid CO₂ particles. Ensure ventilation during operation.

FAQs
Dry Ice Supply and Setup Questions
Why choose HTS708 over HTS705?
Its 7.5 kg tank reduces refills compared with HTS705’s 5 kg tank; both still require matching air, ice and task conditions.
What Is Dry Ice Blasting?
Dry ice blasting, also called dry ice cleaning, is a cleaning and surface preparation method that uses solid CO₂ particles accelerated in a pressurized air stream. The dry ice particles impact the surface and sublimate into CO₂ gas, helping remove dirt and contaminants without water, chemical solvents, or dry ice media residue.
- Use 3 mm pellets as the preferred size. Confirm the nozzle and setup before using anything larger, up to the stated 8 mm limit.
What Compressor Is Recommended For HTS708?
HTS708 requires stable compressed air at 90 PSI or higher. A 1.5 m³/min compressor with a 300 L air tank is recommended. Dehumidification helps prevent dry ice clumping and moisture-related feed problems.
- Check actual dynamic pressure, airflow, and dryness under load.
Does Dry Ice Blasting Leave Residue?
Dry ice sublimates into gas on impact and leaves no solid blast media, while removed dirt, carbon, paint, rust, or other contamination still needs collection.
Can Dry Ice Blasting Remove Paint?
It can remove failing, loose, or weakly bonded paint in some applications, but is not expected to remove strong, well-adhered paint. Results depend on paint and primer adhesion, surface material, pressure, nozzle, and operating conditions; this is not a white-metal or deep-pitting process.
Is dry ice included?
No. Confirm local supply before ordering.
How Does Automotive Dry Ice Blasting Work?
Dry ice blasting works through impact, cold, and expansion. Compressed air accelerates dry ice particles through the nozzle. The low temperature of dry ice helps make contaminants brittle, and the dry ice sublimates on impact, expanding into gas and helping lift contaminants from the surface.
What Do I Need Before Using HTS708?
You need the HTS708 machine, suitable compressed air source, correct power supply, proper grounding, dry ice supply, blasting hose, applicator, nozzles, and protective equipment. Dry ice pellets are not included and should be purchased locally.
What Dry Ice Size Should I Use?
Preferably use 3 mm dry ice pellets. Pellets up to 8 mm may be used when suitable for the nozzle, air supply, cleaning setup, and operating conditions.
How Can I Reduce Dry Ice Blockage Or Clumping?
- Before loading: Use dry air, keep the tank clean, and exclude foreign objects.
- Before blasting: Set ice feed to 0 and check whether condensate exits the nozzle.
- After blasting: Return flow to 0 and run the gun for about 30 seconds to clear remaining dry ice from the tray and tube.
Is Dry Ice Blasting Safe?
Dry ice blasting requires proper precautions. Work in a well-ventilated area, because the machine uses solid CO₂ particles. Wear protective goggles, ear protection, gloves, work clothes, and closed-toe protective shoes. Avoid direct skin contact with dry ice to prevent cold injury.
Where Can I Buy Dry Ice And How Much Does It Cost?
Dry ice is usually purchased from industrial gas suppliers, welding supply companies, or regional dry ice suppliers. Dry ice cost varies by region and supply method. Dry ice pellets are not included with HTS708, so confirm local dry ice availability before ordering the machine.
What Is The Difference Between HTS705, HTS708, And HTS709?
HTS705 is the basic portable model with 5kg dry ice capacity and a lighter 60kg gross package. HTS708 is the standard professional model with 7.5kg dry ice capacity, single pressure gauge, handle, and about 88kg gross weight. HTS709 is the upgraded model with 7.5kg capacity and dual pressure gauges for more precise control.
Can I Customize A Longer Blasting Hose?
The standard blasting hose is 3m. A longer hose may be customized up to 5m with extra cost. Contact AUTOOL Store before ordering if you need a custom hose length.
Can I Return HTS708 After Shipment?
HTS708 is a large machine with relatively high shipping cost and customs cost, so returns may not be supported after shipment. Please contact AUTOOL Store before ordering to confirm voltage, compressor requirement, shipping, tariff, and return policy for your destination.
Can Dry Ice Blasting Remove Rust?
Dry ice blasting can remove loosely adhered rust, surface rust, oxidation, and salt. It cannot remove deeply adhered rust or pitting oxidation, and it is not suitable when a contoured or white-metal finish is required.
