Return Filtr Grille


Those numbers are correct, as long as you remember that they are the AK/free area numbers, not the grille size numbers.

EG: A 20X20 filter grille, is 400 sq in total, but has a AK/free area of only 276 sq in/1.917 sq ft. So at 575 CFM it has a air velocity of 300 FPM, at 767 CFM it has a air velocity of 400 FPM.

Go to Hart&Cooley's website, and download their register/grille specs/tech guides.
