I was just trippin' on your aggravation! It was a trip! I'm stoned,too! But I can solve your problem! Go get any size take-off flange whatever size you want and drill holes in the casing of the fan and mount the flange,or get the kind with adhesive backing! Yeah! get those! or by a peice of whatever size pipe you need and cut a peice dovetail it and hook that puppy up!That way you can use your fan scrubber and do all the tricks ya wanna do! If the fan has enough cfm's?Does it? You know it can be done! Right?
