Any air blower. If it's too weak, stack up MORE. ;-)

Building ventilation / air conditioning often has nice big fans (maybe
TOO big...) Or vacuum cleaners. Paint strippers (those beefier "hair
dryers"). Microwave oven blowers are quite strong too, should be powerful
enough. Then, multiple 12V++ brushless DC motors from PC's and PC power
supplies and really old network routers/switches/hubs. And even a
dead welding supply _might_ contain a good fan. Motor cooling fans from
junk car yards (maybe a bit too large). Just to name a few.
