https://www.surpluscenter.com/home.aspthis vendor has some good prices on the sorts of fans and blowers we might use. I found them recently while in Nebraska. The showroom has more of the hydro stuff and some diesel engines, but the few electrical items are decently priced. The people were also nice. Because of the nice people, I thought to mention the place.
Just a couple of random pics here, these are good for 4CX250's and the like. This kind is hard to find when you need it. Note to differentiate "fans" and "blowers". The best prices seem to be on odd DC voltages or on 230V units, but those are no challenge for us!
All the benefits of being in Nebraska without the surplussalesofnebraska prices!
