This is a vintage Lakewood metal window fan from 1972, suitable for indoor/outdoor use. It has a rectangular shape, metallic finish, and tan color fan. The fan is corded and has a voltage of 110V with a cable length of 60 inches. It has a continuous vent style and one blade. The fan is reversible and automatic, with dimensions of 24" height, 30" width, and 8" depth. 

This works perfectly with 2 speeds, intake or exhaust! it appears that the side panel is expandable by loosing the screws a couple inches. Super rare to find one of these!
