The cold air would enter at the top of the blade and exit at the bottom one foot or so away only cooling that part of the room.

Just another of my random thoughts!
That is exactly what I am working on for my basement shop. Despite accessory air filtration, there will be heck to pay if I create any dust in the house given my wife's sensitivities, so my air system has to discharge outside. For that reason I intend to have as much of the dirty air be the cold air that just entered the house for the buffers and the inside grinder.
