I have a muffin fan rated for 220-240 VAC. When I feed it 110 VAC it self-starts and seems to run just fine. Would there be any long term danger running it at that lower voltage? I ask because I want to use it to vent a battery room for my solar electric system, and just happened to have it in my "spare parts" bin. Also, it gives me just the CFM I'm looking for.
Note that, as a battery room vent fan, it would run 24/7.
