STQX 1100F Backpack Pulsed Laser Cleaning Machine

Core Advantages

1. ✅Backpack portable air-cooled design

Compact and lightweight backpack design, air cooling without chiller. Easy to carry into confined cabins, pipe gaps and high-altitude steel structures. Supports mains power or optional battery module for off-grid operation.

2. ✅Non-contact & substrate-safe cleaning

Pulsed laser with controllable heat input. Only ablate surface contaminants, no grinding or scratching to base metal.

3. ✅Lightweight handheld gun & flexible operation

Light laser cleaning head, flexible for curved surfaces, corners and irregular workpieces. Multiple scanning patterns adjustable on touch screen.

4. ✅Eco-friendly & low running cost

No abrasives, no chemical solvents, no waste liquid. Main operating cost is electricity. Dust extraction interface reserved for dust collection.

5. ✅Stable for harsh site environment

Anti-shock compact cabinet, suitable for workshop, construction site, shipyard and other rough working conditions.

Application Fields

• Steel structure rust removal, bridge & equipment on-site renovation
• Ship cabin, deck, weld seam cleaning in confined space
• Rail transit: bogie, rail fittings rust & oxide removal
• Pipeline, valve, pump body maintenance
• Pre-weld oxide & slag removal for field welding
• Partial paint stripping & oil stain removal for heavy machinery
• Auto heavy-duty equipment field maintenance

Project Case

Steel Structure Bridge On-Site Rust Removal Project

Industry： Infrastructure & steel structure engineering Workpiece： Outdoor bridge steel beam with thick floating rust and aged paint. Many working areas are high altitude and narrow gaps, inaccessible for large cleaning machines. Challenge： Sandblasting requires heavy equipment, generates massive dust and needs enclosure protection; chemical cleaning cannot work at high altitude and produces hazardous waste. Solution： OPRAY STQX1100F backpack laser cleaning machine. Result：

1. Quick removal of rust and old paint layer, clean substrate surface ready for re-coating;
2. Backpack design allows operators to reach high-altitude and hard-to-access areas;
3. No dust pollution or chemical waste, meets site environmental regulations;
4. No damage to steel substrate, saves site setup time and reduces project downtime.
