RC EXFUSION Smoke Dilution & Exhaust System — Smoke Dilution & Fresh-Air Exhaust System (No Gas Needed)
EXFUSION is an exhaust-air dilution system designed to reduce smoke concentration and exhaust temperature while improving coffee-roasting exhaust conditions. By mixing the roaster exhaust with fresh air, it stabilizes smoke discharge without a burner or gas consumption, offering simple installation and low operating costs.
