As said earlier you are correct which is why the manual makes no sense.? 4500 fpm would mean 1200 cfm.? 2700 cfm would be 10,100 ft per min.?

Joe, your CFM calcs are mistaken.

> For a 7¡± port:?4500 ft per min velocity equates to 4810.56 cu ft/ min

7" diameter has area of pi*3.5^2 = 38.5 square inches, divided by 144 = .267 square feet.

0.267 sq ft * 4500 feet/minute velocity == 1,200 CFM
