Gauging interest in a compatible replacement fan.  Specs on the fan will be almost identical with what you would be able to get on Amazon with the exception of the cord being .45 meters or about 1.5 ft and going to 22 AWG instead of the standard 24.  My hope would be going to a larger gauge cord would give the fan better longevity in a mining environment. Cost would be around $22.00 shipped in the continental USA so not a great cost advantage over amazon but you would get a longer connector cord and larger gauge wire. Please let me know your thoughts concerns or improvements.

Second issue is I do not mine anymore so I would need some trusted members (two) to test out the fan if their is enough interest I can have the factory get to work.
