Powder Recovery & Overspray Reduction: GEMA Practices for Efficient Processes

Excessive overspray leads to powder loss, high dust levels, and lower efficiency. GEMA recommends proven recovery methods for sustainable and clean processes.

🔍 What Does GEMA Mean by Overspray?

Overspray is powder that doesn’t adhere to the workpiece. It falls to the cabin floor or is extracted with the air. GEMA describes structured recovery via extraction, sieving, and cyclone separation.

🛠️ GEMA Solutions & System Equipment

• Cabin Floor Scraper & Fluid Channels: Direct overspray to sieve/cyclone separator.
• Cyclone & Panel Filters: Separate powder from air and collect it for reuse.
• Sieve Machine / Ultrasonic Sieve: Removes contaminants like particles, dust, or clumps before reuse.
• Powder Pumps & Recirculation: Transport cleaned powder back to the container, ready for reuse.

✅ Benefits of Closed-Loop Recovery

• Lower powder consumption through reuse
• Cleaner cabin environment & reduced dust levels
• Consistent coating quality due to uniform powder
• Reduced cleaning and maintenance effort

📌 Conclusion

GEMA recommends an integrated system of scrapers, extraction, cyclones, sieves, and feed pumps – for maximum recovery, clean environments, and process optimization. Use systems like MRS-E or OptiCenter to boost efficiency and reduce costs.
