Backward centrifugal fans refer to a type of centrifugal fan where the blades of the impeller are curved backward relative to the direction of rotation.In these fans, when air enters the impeller, it is accelerated and then discharged in a direction that is more towards the tangential direction of the fan casing. Compared to other types of centrifugal fans , backward centrifugal fans typically have higher efficiency, better aerodynamic performance, and can operate more stably under a wider range of air volume and pressure conditions. They are commonly used in various industrial and commercial applications that require efficient air movement, such as ventilation systems, air conditioning systems, and industrial processes where air needs to be moved with relatively high pressure and efficiency.
