The wind gate adopts a steel plate pressure folding structure. The blade is a streamlined diamond -shaped structure of the sharp corners at both ends, which can change the distribution of the tail flow of the air. Its adjustment feature is that within the range of 25 degrees to 75 degrees of the blade, the resistance coefficient and opening are closely linearly proportional; the wind gate has driving methods such as electric, manual, pneumatic,; Essence The bearing of the bearing is equipped with a sealed air interface, which can be connected to the sealing air to block the hot air leakage (optional).
