Aircom filtration system ensures safe and quiet working conditions in melting pot applications
Coral, leading global provider of industrial dust extraction and air filtration solutions, has successfully delivered a customized Aircom filtration system to support RG Tech, a major Chinese manufacturer of shot blasting and surface preparation equipment. This installation further demonstrates Coral’s commitment to enhancing workplace safety and air quality in demanding industrial environments such as foundries.
Meeting the challenges of foundry dust, fume and noise
Located in Qingdao, China, RG Tech operates large-scale melting pot production lines for non-ferrous metals. These processes generate substantial amounts of fine dust and fumes, along with high noise emissions that can impact worker health and regulatory compliance.
RG Tech required a solution that could:
- Capture and filter fine dust particles down to 1 micron with high efficiency.
- Maintain low noise levels to improve operator comfort.
- Operate reliably in heavy-duty, continuous production cycles.
- Integrate seamlessly with existing ducting and control systems.
Coral’s advanced Aircom solution
Coral proposed a turnkey Aircom filtration system designed specifically for RG Tech’s operational requirements. The installation included:
- Two Aircom filtering modules with:
Airflow capacity: up to 70,000 m³/h
Filtration surface area: up to 648 m²
Filtration efficiency: ≥99.9% for fine foundry dust
Noise level: ≤75 dB(A), thanks to the integrated soundproofing enclosure
Automatic pulse-jet cleaning system for continuous operation - High-efficiency fans, housed in acoustically insulated compartments to further reduce noise emissions.
- Heavy-duty ducting and fittings for dust collection directly from the melting pots.
- Electronic control panel with PLC monitoring, automatic filter cleaning cycles, and alarm systems for differential pressure control.
The Aircom filter’s modular design allowed Coral engineers to tailor the configuration to the available footprint and ensure optimal performance under continuous load conditions.
Results and customer benefits
Following installation, RG Tech reported:
- A significant reduction in airborne dust and improved air quality across the foundry workspace.
- Noise levels comfortably within regulatory thresholds, enhancing worker wellbeing.
- Reduced downtime and maintenance costs thanks to the self-cleaning filter system.
- Consistent, reliable performance in intensive production scenarios.
These results underline the Aircom system’s suitability for challenging foundry dust collection applications.
