Technical Description

450mm DC axial fan, primarily used in central air conditioning fan coil units. These 48V DC fans operate at a safe, low voltage, making installation hassle-free. It is an external rotor axial fan—with the stator located in the center and the rotor on the outside—where the motor directly drives the impeller. This design offers high efficiency, low noise, light weight, and a compact size, making installation and maintenance extremely convenient. Designed specifically for fan coil units in central air conditioning systems, it delivers gentle, quiet airflow with high heat exchange efficiency. Its flush-mounted design saves space and allows for universal replacement in both new and existing units.
In terms of duct design, the fan coil’s volute and condenser have been optimized to ensure smooth axial airflow, delivering uniform air distribution throughout the entire space with no dead zones or discomfort caused by direct drafts. The widened, streamlined impeller, combined with precision dynamic balancing, ensures quiet operation and minimal resonance. It is particularly suitable for commercial buildings, hotels, guesthouses, hospitals, offices, and other venues requiring continuous year-round operation. As a high-airflow axial fan, it rapidly circulates air through the coil heat exchanger, enabling more thorough heat exchange and faster cooling or heating, which naturally reduces air conditioning energy consumption. The compact and lightweight unit fits seamlessly into various horizontal concealed, vertical exposed, and cassette-style fan coil units. Installation is hassle-free and effortless, requiring no structural modifications and occupying no ceiling space.
