This ducted fan coil unit is designed for high efficiency, durability, and stable performance in commercial and residential HVAC applications. It uses a high-quality galvanized steel casing, precision-engineered copper tube & blue fin coil, and a forward-curved centrifugal fan to ensure strong air delivery with low noise operation. The unit is factory tested to guarantee cooling and heating performance and is suitable for concealed ceiling installations where compact size, reliability, and quiet operation are required. Optional components such as air filters, stainless-steel drain pans, extended drain pans, and plenum boxes allow flexible configuration to meet different project needs.
