Two-way fan

550Doug · Aug 12, 2021

I have a large 2-way fan, about 2 feet in diameter, where moving the switch up blows air one way, and moving switch down blows air in reverse direction, Center position is off.
I'm now looking for a 6 inch fan of similar design but having some trouble. I would like this fan to run off DC voltage, but AC could also work. Any ideas?

Brushed 12v DC motors used on heater blower motors, and permanent magnet motors, are able to operate either way depending on the voltage polarity.
(Universal Motor) The blades for many fans are curved for one way push or pull. Flat blades are less common, and noisier, but will blow or suck with
change in rotation. Jim
