The key points that cannot be ignored when measuring the air leakage of galvanized duct In view of this knowledge, we have learned about the knowledge of checking the air leakage of galvanized air ducts. First of all, we must have the awareness that this is a key factor related to whether the entire galvanized air duct can be more applied. So we must test it well before applying it. It is particularly important to note that when we measure the air leakage of the galvanized air duct at night, the surrounding environment is dark, and the 100W low-voltage illuminator with a protective cover is placed inside or outside the duct, along the detection part and the connection Sew the seam slowly and observe on the other side. When light is found to be emitted, it means that the obvious air leakage is found, and a record is made.
