Cheap intake/exhaust fan for tent

For those that are in a tent and venting in the room or garage, you can use a tabletop hepa filter. I started growing indoors in a 4x4 tent with leds. Since I knew my air demand wasn't as much as with HPS, I found (my wife:mrgreen:) this air purifier for $5 at a garage sale. The filter was like new. We used it in our house for about a week before the noise drove us nuts. This thing draws about 1.5A, so it can really move some air. With it mounted to my tent, it looks like the tent is going to blow up. The filter is about 16" in diameter and 14" tall. You unscrew the filter with a long T-handle and you mount half on top and the other half inside. I did cut the intake sleeve down to an inch. When used as an intake, The motor side sits perfectly on the dropped cross bars. If running a 1000w, one on a lower hole and one on top should easily move enough air when put an a plug-in temp switch ($50 to $80).
I can find the pic on the tent. And now it's mounted in the attic with a charcoal filter replacing the hepa filter.
