4/5Let me reverse lookup
Love that it gives you different options for sizing but I wish I could enter a duct size and get a cfm value from it.

Excellent application. Don't be afraid to invest in this very useful tool. The application perfectly meets its objective. I recommend it 100%

2/5It’s ok at best
Can’t punch in duct size to see what the cfm is very limited on what you can do save your money but it gives you different duct options if that’s what your trying to do

3/5Pretty useful
Comes in handy but limits what sizes you can pick. Not sure if it’s a bug but I wanted to see what my friction rate was for 16x25 and I can get the 16 but it skips from 24-26 and that happens often.
