Vintage Atlas Aire box fan, machine age industrial floor or window fan
Vintage Atlas Aire box fan, rewired at some point, and working well at both high and low speed. It measures 15" x 15" x 5 1/2" overall.
This doesn't look like a collector's piece, as there's a lot of wear, soil and surface rust to the original finish. But it runs quietly and moves a lot of air - they don't make 'em like this anymore!
