Hi,
I am installing a bathroom exhaust fan. The duct run consists of a section of 6" round aluminum flex duct, 6" round metal duct, and terminates with a 6" wall cap like the one pictured at the following URL:

What I am trying to find out, is the approximate equivalent of this style of wall cap, in feet. For instance, the tech specs of my particular fan says it can accomdate runs of 50 feet of 6" ducting. I found the conversion for the flex duct (it was 2x), but have not seen anything for the wall cap.Does anybody know the conversion for a 6" wall cap, so I can use it in my calculation and make sure I my duct system will perform adequately?
Thanks,
Scott
