A Wet Sand Blasting Machine mixes abrasive with water and compressed air to clean or prep surfaces. It removes rust, old paint, scale, oil stains, and graffiti. Compared with dry blasting, the water traps dust, reduces rebound, and cools the work surface. This means cleaner air, safer jobs, and a smoother finish. The process also reduces heat buildup, thereby minimizing the risk of warping thin metal panels or micro-cracking concrete edges.
Why It Stands Out Versus Dry Blasting
- Better Dust Control: Water encapsulates airborne particles before they spread.
- Eco-Friendly: Less dust escaping means easier compliance with site rules.
- Cooler Cut: Water cools the surface and the media, protecting heat-sensitive coatings or substrates.
- Smoother Finish: Moist media reduces impact marks and helps avoid peening thin sheets.

Wet Blasting Equipment: Working Principle
This section explains how wet blasting equipment operates. The system draws abrasive media (e.g., garnet, glass bead) from a pressure pot. Water enters the flow either inside the pot (slurry style) or at the nozzle (injection style). Compressed air accelerates the water-media mix through the nozzle. The high-speed stream hits the surface, breaks the bond between the coating and the base, and washes away residue. Because water surrounds each particle, dust falls quickly, and cleanup is easier. Many units include a fine metering valve so you can set the exact media and water ratio for the job.
Process Steps:
- Fill the pot with media and connect the water supply.
- Adjust air pressure, water flow, and media feed on the control panel.
- Test on a small area to confirm profile and removal rate.
- Sweep the nozzle at a steady speed and overlap each pass.
- Rinse and check the surface profile before repainting or coating.
Key Components of a Dustless Sandblasting Machine
A modern dustless sand blasting machine combines rugged hardware with simple controls so crews can work fast and safely.
- Pressure Pot (Blast Tank): Stores and pressurizes media; rated for industrial air pressures.
- Spray Gun / Blast Handle: On/off trigger with safety lock; ergonomic grip for long shifts.
- Nozzles: Carbide or boron nozzles in multiple bore sizes for different removal rates and profiles.
- Water System: Inline injection or slurry mixing with a filter, flow meter, and shutoff valve.
- Hoses & Couplings: Anti-kink blast hose and water hose with quick connectors and safety pins.
- Air Regulation: Gauges, regulators, and moisture traps to stabilize pressure and protect parts.
- Control System: Manual panel or remote on/off; some models add timed rinse and media purge.
- Mobility Base: Skid, wheel cart, or trailer frame for site moves.
Wet Abrasive Blasting Machine Parameters
Choose a wet abrasive blasting machine that matches your daily workload, removal speed, and compressor size. Below are typical ranges (custom specs available):
| Model | YG-600 | YG-700 | YG-800 | YG-1000 |
| Volume(m3) | 0.26 | 0.3 | 0.6 | 1 |
| Height | 1150 | 1250 | 1700 | 2000 |
| Sand peening capacity | 5-10(m3/h) | 6-11(m3/h) | 10-12(m3/h) | 10-30(m3/h) |
| Air source configuration | 3(m2/min) | 3(m2/min) | 3.5(m2/min) | 4(m2/min) |
| Control System | Air control | Air control | Air control | Air control |
| Diameter | 600mm | 700mm | 800mm | 1000mm |
Tip: Match compressor output to the chosen nozzle. An undersized air supply will slow the removal and waste media.

Media Selection Guide
Pick media that fit your target profile and substrate:
- Garnet: Fast, clean profile on steel; low embedment.
- Crushed Glass: Good for paint and graffiti removal on concrete and brick.
- Glass Bead: Gentle peening and satin finishes on stainless parts.
- Aluminum Oxide: Aggressive cut for heavy mill scale or hard coatings.
Adjust pressure and water flow to tune the surface profile (e.g., SP10/NACE 2 vs. lighter SP7/NACE 4 cleaning).

FAQs About Wet Sand Blasting
Q1: Can I use tap water?
Yes. Filter it to remove grit; use a corrosion inhibitor for bare steel if flash rust is a concern.
Q2: What compressor do I need?
Match CFM to nozzle size. For an 8 mm nozzle, plan around 240–300 CFM at 7–8 bar.
Q3: Which media is best for concrete?
Crushed glass at moderate pressure often gives quick paint removal with minimal surface damage.
Q4: Will it damage thin sheet metal?
Wet blasting lowers heat and impact. Use smaller nozzles and lower pressure for thin panels.
Q5: How do I prevent flash rust?
Rinse, blow dry, and apply primer quickly. Use inhibitor dosing if the humidity is high.
