I think I know what you are talking about - they are called Air Movers. You actually might get a better price buying one through a restaurant supply store or even Sams Club - I think I saw some there once. They are made to blow air at a high rate to quick dry floors that are wet. I have seen them in a few trailers over the years. We just use a small none-pedastal fan we set near the intake after a run to shock the temp down a bit. Beth
Found a link to one if this is what you are looking for:
