風量調整ダンパ。 The damper body has a passage for gas to flow inside and is attached to the damper body so that the gas passage area of the passage can be changed by changing the opening degree, and the gas flow rate discharged from the damper body is zero when fully closed. In the air volume adjustment damper, the damper has an opening having a size such that a change in gas flow rate becomes a predetermined flow rate for a unit opening change of the damper blade part. A fine-tuning air volume adjustment damper characterized by having a hole in the damper blade.
