Who has a newer GQF cabinet?

[fire370]

In one of my cabinets I built several years ago I was running a single 240cfm fan from GQF and it shot craps yesterday. So I went to order a new one and saw the newer style dual fan set up they are putting in the new ones so I ordered it instead. I’ll have to do a little rework to get it in there but that’s no biggy. GQF said it was 240cfm just like the single. For those of you that have these, how do you like it and if you had an older single fan cabinet, your thoughts on comparison? And can somebody measure their set up so I can get a start on this (side to side and top to bottom of the metal housing the fans are in). I’ve looked everywhere for the specs and no luck. Thanks!
