I have a 7kw BL series Markon that I need a cooling fan for. I priced one once and it was outrageous. It still makes power, but I think the mice build a nest in it and and all the fan blades are missing.
Tom,
I'm not sure how I missed your post.
Wow, mice ate the fan!

They might have a fan. Or possibly a trashed rotor with a good fan.
They are a great bunch of guys.
