Smacna leakage class 5

WebbLeakage Class indicated in Table 1. The SMACNA Leakage Class (C L) is determined using the following relationship: Where: C L = F/p 0.65 C L = Leakage Class, which is the permissible leakage rate in CFM per 100ft2 of duct surface F = Leakage Factor, CFM per 100ft2 of duct surface. Varies with s.p. p = Duct static pressure, in. w.g. WebbMETAL DUCTS 233113-5 b. Minimum SMACNA Seal Class: A. D. Elbow Configuration: 1.
