Nice score! I've got a 3 inch 12v fan from an old UPS that I'm going to re-purpose as a ventilation fan, solar powered, in my sailboat. It draws some very small current, I'm thinking it is 25 mA or so. Planning to put a 50W panel on a controller to both charge the boat's deep cycle battery and run the fan, with a fan cut-off at 12.5 volts or so.
If I had one of those big fans it would be mo-better, but I'd have to fabricate a new hatch and install that fan in the hatch, with some type of weather cover to keep the rain out. ------------- Max Charleston SC On Wed, Feb 17, 2021 at 1:35 PM Jim Cathey via Mercedes < mercedes@okiebenz.com> wrote: > Speaking of fans for wood stoves, I was at the thrift shop yesterday and > found > two 8" 12V fans.
