This is probably not common knowledge, but I've been collecting AC condenser fan blades since around 2015 or so. I'm not sure why young me didn't post much about them, but regardless, here we are in the present, and I'm pleasantly surprised that you enjoyed my previous condenser fan video a LOT, so here's a similar video with more different fan blades in it!
I learnt several things from making this video. The most obvious being the development from boring 4 blade fans from the 80's that was made to simply move air & be quiet, to the current day's swoopy jagged edge fan blades designed to save electricity & be as silent as possible, as proven by the rather big contrast of power consumption between the 2010's Sharp & 1980's Daikin fan blade, even though they're both 15 inches in diameter, have similar overall blade pitch & move roughly the same amount of air.
This video showcases most of my counterclockwise rotating condenser fan blades, running on a 1980's Daikin fan motor & a 1990's Mitsubishi Heavy Industries fan motor. I have quite a bit more clockwise rotating blades if memory serves me right, and if you want to see them in a video like this, just pop in the comments!
