WebbTesting Range : 45 sq m to 100 sq m under 2” pressure and 25 sq m to 80 sq m under 4” pressure. Calculate the surface area of duct section to be tested. Connect the Flexible Adaptor of Testing Machine to the duct section to be tested. Connect the Pressure Sensor to the duct. Make sure all the openings of the duct are closed. WebbThe maximum permitted duct leakage is “Class 4” – 4 CFM per 100 ft2 of duct surface at 1” WG. You need look no further than the SMACNA HVAC Air Duct Leakage Test Manual to see it clearly shown that the expected leakage of a properly sealed rectangular Class A sealed duct system is Class 6. For round and flat oval duct systems it is Class 3.

WebbThat Duct Leakage Class is 4 cfm/100 ft2 at 1” WC. Rectangular duct meeting the required Seal Class A is expected to leak 50% more than the allowance. Round and flat oval spiral duct is expected to leak only 75% of the allowance. Perhaps we should pause a moment to let these numbers sink in.
