Okuma LB-15 Cooling Fan for electronics cabinet

Hello,

We have a LB15 which needs to have one of the cooling fans replaced. There are a total of 2 fans which keep the electronics cabinet cool.
Does anyone know where we can purchase fans? We've tried local rep and Okuma is working on a resolution.
The newer fans they supply do not fir inside the cabinet. Waiting to hear back from Okuma. The fan is sort of "oblong" shape, not square.
Has to be a certain size to fit our plate and into the cabinet area.
200 volt fan. Previous fan was from company called Style Fan from Japan. Have not been successful in finding source that will supply the same fan, which we replaced in 1997.
Tried Dayton motors, even looking on line. I'm hopeful another supplier with Okuma may have a replacement part. Waiting to hear back from our local Okuma rep.
Any help or idea would be appreciated.
Thank you,
Duke

Thank you for providing information on All World Machinery.
Will contact them regarding Okuma replacement parts.
We tried Dayton earlier, will need to use their fan and possibly create a bracket for cover plate.
