5 Things to Know Before Buying Dry Ice for a Dry Ice Blasting Machine
If you plan to use a dry ice blasting machine, choosing the right dry ice is critical for performance and cost efficiency.
The quality, size, and freshness of dry ice directly affect cleaning results. In this guide, we’ll cover the five key things you need to know before buying dry ice for blasting machines in the United States.
1. Choose the Right Pellet Size
Most dry ice blasters, including the Aiolith AI30, require dry ice pellets of 3 mm (1/8 inch) or smaller. Larger pellets can clog hoses, while powdery dry ice reduces cleaning impact. Always confirm your machine’s specifications before ordering.
2. Prioritize Freshness
Dry ice sublimates quickly, turning from solid to gas at about 5–10% loss per day in insulated storage. For best results:
- Use dry ice within 24 hours of delivery.
- Avoid storing it for more than 2–3 days.
- Order in smaller, frequent batches instead of stockpiling.
3. Store Safely and Properly
Dry ice must be stored correctly to remain effective and safe:
- Use vented insulated containers designed for dry ice. Never use airtight coolers.
- Keep storage areas well ventilated to prevent CO₂ buildup.
- Do not store dry ice in standard freezers—temperature fluctuations will cause faster sublimation.
4. Where to Buy Dry Ice in the U.S.
Dry ice is widely available across the United States from several sources:
- Gas and welding supply companies (Airgas, Praxair, Matheson)
- Large retailers (some Costco and Walmart stores carry dry ice seasonally)
- Specialty dry ice suppliers (regional companies that deliver to industrial clients)
For consistent pellet size, many blasting professionals prefer to work with specialty suppliers who provide 3 mm pellets specifically for blasting machines.
5. How Much Does Dry Ice Cost in the U.S.?
Dry ice prices vary by region, supplier, and volume. Below is a quick reference:
| Quantity | Price Range (per pound) | Notes |
|---|---|---|
| Small retail purchase (10–20 lbs) | $2.00 – $3.00 | Available at supermarkets or gas suppliers |
| Bulk order (100–500 lbs) | $0.70 – $1.50 | Lower cost per pound, delivery usually required |
| Industrial contract (>500 lbs/week) | $0.40 – $0.70 | Best for consistent blasting operations |
Example: Aiolith AI30 Blasting Machine
To illustrate why the right dry ice matters, here are the key specifications of the Aiolith AI30:
- Voltage/Frequency: 110V / 60Hz
- Hopper Capacity: 44 lbs (20 kg)
- Dry Ice Output: 0.66 – 1.32 lbs/min (0.3 – 0.6 kg/min)
- Air Pressure Input: 87 – 116 psi (adjustable)
- Air Flow Rate: 71 – 141 CFM (2 – 4 m³/min)
- Allowable Pellet Size: ≤3 mm
- Dimensions: 28 × 24 × 37 in (705 × 610 × 940 mm)
- Weight: 135 lbs (61 kg)
- Recommended Compressor: ≥10HP, ≥150 gallon tank
Because this machine requires 3 mm pellets, choosing the wrong size dry ice could interrupt cleaning, reduce efficiency, and increase costs.
FAQs About Buying Dry Ice for Blasting Machines
1. Can I use dry ice blocks instead of pellets?
No. Dry ice blocks are too large for blasting machines and can damage equipment. Always use pellets of 3 mm or smaller.
2. How long does dry ice last in storage?
In an insulated container, dry ice typically lasts 24–48 hours. Expect a loss of 5–10% per day depending on container quality and room temperature.
3. Can I store dry ice in my freezer?
No. Regular freezers are not designed for dry ice. The extreme cold can damage the freezer, and sublimation will still occur quickly.
4. How much dry ice should I order for the Aiolith AI30?
The Aiolith AI30 consumes 0.66–1.32 lbs per minute. For one hour of blasting, you will need approximately 40–80 lbs of dry ice.
5. Where can I buy dry ice in bulk in the U.S.?
Check with Airgas, Praxair, or regional suppliers. For industrial use, it’s best to set up a delivery contract to guarantee pellet size and supply.
Conclusion
Buying dry ice for a blasting machine in the U.S. requires more than just finding a local supplier. You need to focus on pellet size, freshness, storage, supplier reliability, and cost. For machines like the Aiolith AI30, only 3 mm pellets will deliver consistent results.
By following these five guidelines, you’ll ensure your blasting machine performs at its best while keeping operating costs under control.
