An OEM (Original Equipment Manufacturer) centrifugal fan is a highly efficient and versatile mechanical device designed to move air or other gases in a wide range of industrial, commercial, and residential applications. These fans are engineered to meet specific performance requirements and are often customized to suit the unique needs of the end-user or the equipment they are integrated into. Centrifugal fans are characterized by their ability to generate high-pressure airflow, making them ideal for applications where air needs to be moved against resistance, such as in HVAC systems, industrial ventilation, air purification, and process cooling. Design and Working PrincipleThe core design of a centrifugal fan consists of a rotating impeller housed within a scroll-shaped casing. The impeller is equipped with blades that draw air into the center of the fan and then propel it outward radially due to centrifugal force. As the air moves through the impeller, its velocity increases, and the scroll casing converts this kinetic energy into static pressure, enabling the fan to push air through ducts or other systems efficiently.The impeller design can vary depending on the application. Common blade types include forward-curved, backward-curved, and radial blades. Forward-curved blades are typically used in low-pressure applications like HVAC systems, while backward-curved blades are preferred for high-efficiency, high-pressure applications. Radial blades are often chosen for their durability in handling particulate-laden air. Key Features and Benefits1.
