💡 Field Controls 46649302 14-Inch UVC Replacement Lamp – Model DUO-14/24V
🧭 Product Overview
The Field Controls 46649302 is a 14-inch UVC replacement lamp designed for use with the DUO-14/24V model. This high-efficiency ultraviolet lamp helps neutralize airborne microorganisms by disrupting their DNA, preventing replication. As air circulates through the HVAC duct system, it is continuously exposed to UVC light, improving indoor air quality and helping maintain a cleaner HVAC system.
Independent laboratory testing shows that Field Controls UVC lamps reduce airborne bacteria by up to 90% in a single pass, with cumulative benefits over time.
✅ Key Features
🔹 14-inch UVC replacement lamp – specifically for DUO-14/24V systems
🔹 Neutralizes microorganisms – disrupts DNA to prevent replication
🔹 Cumulative air purification – each air molecule passes the lamp 75–150 times daily
🔹 Lab-tested efficiency – reduces airborne bacteria significantly with a single airflow pass
🔹 Helps keep AC coils clean – reduces mold, biofilm, and germ buildup on A-Coils
🔹 Improves HVAC efficiency – maintains system performance, reduces energy costs, and lowers maintenance
🔹 Extends equipment life – protects coils and system components from microbial buildup
