The DBF and BF Box-Type Centrifugal Fans are compact, low-noise ventilation units designed for commercial and industrial HVAC applications. Combining high-efficiency centrifugal impellers with sound-insulated cabinet structures, these fans provide stable airflow, reliable pressure performance, and quiet operation.
Their enclosed box design not only reduces noise but also simplifies installation and maintenance. Widely used in office buildings, shopping malls, hotels, hospitals, schools, factories, and ventilation systems, DBF and BF fans are ideal solutions for air supply, air exhaust, and fresh air circulation.
