Dust Collection System for Foundries

Foundries generate heavy dust and fume loads during metal casting processes such as sand handling, shakeout, furnace charging, and grinding. A well-engineered dust collection system captures and filters airborne particulates to ensure cleaner air, regulatory compliance, and safer working conditions.

Synergy Spray Systems specializes in the design, manufacture, and installation of high-efficiency industrial dust collection systems for foundries. Our solutions are tailored to handle extreme dust loads, abrasive particles, and high-temperature gases typically found in metal casting and finishing operations. Engineered for both ferrous and non-ferrous foundries, our systems ensure a clean and safe environment while helping you stay compliant with CPCB, OSHA, and NFPA standards.
