DC fan (reversible)
DC fan (reversible)
(OP)
I am trying to find a DC fan that I can reverse. I am looking for something about the size of a computer cooking fan 3"-5" square. Preferably a throughput up around 100 cfm but that's negotiable. Thanks for any help.

Regarding the fan, it should be a propeller fan so that it can work in both directions.

I have reversed several fans with a CMOS 4053 analog mux. Mail me for pics and schematics.

The only fan that I know of that you can buy is this one:

it is very expensive and big (6.8" diameter)
