I may be wrong, but from what I could tell these are bog standard 10 
inch blowers of a sort used in all kinds of equipment.  They can be had 
new from Mouser, etc. for $75-ish.  (I used an OA254AP-11-1TB, as 
indicated below, but I suspect the 10 inch diameter and 500-600 CFM are 
all that's important.  Maybe the noise rating, if you're fussy.)

What I did was to order one of these:
https://www.ebay.com/itm/313353225252
and kept the original mounting bolts, grill, etc.  I did fabricate a new 
zip-cord over to the AC connector thingy, soldered on the fan end (like 
the original) with the crimp-on circular ends to go under the screws in 
the terminal strip.

That eBay order did take a while to ship, but it when it arrived it went 
in right where the old one was and blows like the old one, but is nice 
and quiet.

If it had been important to me to keep the original branding, etc., I'm 
sure new bearings could have been fitted instead.  There is no branding 
consistency amongst my racks, though, and the old brands and models are 
all discontinued in favor of newer and higher efficiency, so I didn't 
feel that extra effort was necessary.

Oh, and I think you need the -22- instead of the -11- if your power is 
closer to 220V than 110V.
