Fans for small enclosures
(OP)
My company used Comair-Rotron fans for 40+ years, but now with their demise we need to find a replacement brand. We no longer have an R&D group to do product testing. We need a brand with a good cross-section of 60mm, 80mm and 4" ball-bearing fans in AC and DC.
What brand fan has your company actually tested and used successfully?
Thanks in advance for your help.

However, I'm not about to risk my company's good name by buying start-up fans from China.

itsmoked's list is pretty good. Delta was the only name I didn't see.
I found EBM-Papst has good technical info on their webpage.
All of the electronics distributors have a large selection of fans from any of those vendors. The sizes you list are also very common.

Exactly my fear. When trying to cool electronics in any box, there is always decreased flow, so that's the source of my inquiry.
In a previous R&D position (~1994) I tested axial fans for flow under various restrictions for outdoor telecom cabinets. Of course all the axial fans had decreased flow, but Rotron did much better than the others. They also did better in a salt spray environment.
By the way, in those tests the second runner up was EBM, and the last place all-out looser was NMB. But to be clear, that was only 6" fans and more than 15 years ago.
Thanks all.

That is what fan curves are for.
