Bill, I have my Clear Vue exhausting outside. See pics starting at post #15 here: http://familywoodworking.org/forums/...read.php?t=252
My outlet went to a metal 8-6-6 wye, then thru 2 short sections of 6" flex to de-couple the cyclone from the building (my cyclone is mounted to a separate stand that is also isolated from the building) to to 6" louvered "dryer " vents. The one picture of the vent shows that it has a plastic grid that keeps the big critters out and the birds from making a nest in the pipe or getting to the cyclone. The louvers help too that they drop back to the down position when the unit is not in use, and I'd like to see the animal that could get in when it's running....well, maybe not. I got the louvers at Lowes, Home Depot only had 4" units. so far the plastic has held up well, but if it ever goes bad, I think I could replace it with some wire mesh f some sort. Hope this helps! Jim.
