ช่วงแรงดันปานกลาง (50-1000 มิลลิเมตรน้ำ)

The centrifugal fan induces airflow by the centrifugal force generated in a rotating column of air producing potential energy (SP) and also by the rotational (tangential) velocity imparted to the air as it leaves the tip of the blades producing kinetic energy (VP). Centrifugal fans may be classified into three basic types according to blade configuration: 1. Forward curve 2. Backward curve 3. Radial or straight blade Each type has its own application range and limits. Modifications of these basic types include radial tip, mixed flow, and tangential flow. The tip speed required to produce the required air particle velocity varies substantially with the type of blade used.
