Lostpedia claims "The device he brought upstairs makes and spreads
cold air. It's a common device that real-life ghostbusters use to
flush spirits out of their hiding places."
I know that ghosts are often associated with cold air, but I haven't
found any source that describes this kind of device (regardless of
whether it looks like what we saw) or its use by ghostbusters. Maybe
someone else will have better luck.
