Duct Leakage Testing - NEBB
www.nebb.orgDuct Leakage Measurements • % of Flow requirements – Problem: Disregards size of ductwork & static pressure – i.e. 1% of flow on 3900 cfm system = 39 cfm. If 1300 ft2 duct area = 3 cfm leakage / 100 ft2 300 ft2 duct area = 13 cfm leakage / 100 ft2 • Test pressure requirements – Problem: Test pressure higher than duct design
