You may recall that our first heat-wave in early June necessitated a quick installation of my 12v ceiling vent fan. Without taking the time to do a proper install it looked tacky.
Furthermore, the unit was noisy, having been designed to supplement a car’s radiator cooling where engine noise was presumed to drown out its racket. So I bought what’s called a potentiometer – a fancy word for a controller that adjusts current and therefore fan speed. I also bought a reverse polarity switch so that when needed I could change the fan’s direction, bringing air in, not pushing it out.
After several attempts, I could not get the reverse polarity switch to work. I kept blowing fuses. So I abandon that effort, settling for variable speed – a good solution for now.
I also built a crude birch wood grate to give a more decorative touch to the whole thing. Have a look:
It’s so much quieter in here.
