🍃 Friday Video - Forward Centrifugal Impeller 📌 Forward curved centrifugal fan are divided into two types: insert type and rivet type, and the one shown in the video is the insert type. The insert type has an insert at both ends of each blade, and the inserts are inserted into the hub for fixation. Welding and fixing the inserts requires a lot of steps, but one advantage is that the fan impeller has a long service life and is not easily deformed. 👍 CHOSEN is your ventilation expert. 📞 0086 1
