The sam-pling tube length must extend at least 5/8 across the duct width for optimal performance. The sampling tube is always installed with the air inlet holes facing into the air flow. To assist proper installation, the tube’s connector is marked with an arrow.
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
