That's interesting. Now I want to learn what a vacuum excavator is. I bet it's fun. But I know my phone's eavesdropping because I was having a conversation about how I could measure the CFM in my HVAC ducts, and this came up. I'd need one with more cross sectional area. This could measure my central vac too. Cheers!

Your friend should have been more forthcoming on the “science” of “airflow”!
