Is it true to say that round ventilation ducts with a single gasket generally achieve airtightness Class C?

Although this seems to be true, this is a dangerous generalization. There are many factors that govern airtighness of round ductwork, including roundness (any slight ovality can cause leakage at the joints) and the flatness of the seams at...
Ask the Experts

Is it possible to use the HVAC fan itself to measure the airtightness of the ductwork in a ventilation system?

This is generally not possible. In systems with good airtightness, the leakage flow rates are too small for one to be able to accurately measure the flow rate over the fan.For more information you can check-out the Webevent presentation “...
