If you are still looking for a reversible fan for the H8080, I could also provide you a quote for a reversing fan. I work for Cleanfix reversing fans and we are the company that CNH has approved to have their fans installed on the NH 8000 series and CIH WD"3" series windrowers. They have service bulletins issued to inform dealers of our fan installation on the windrowers.
Please give me a call @ 1-855-738-3267, or email me @ [email protected]
I saw your message about the 2012 NH H8080 used around Oyen, and how you had to stop every five hours or so to blow out the rad/screen all summer. We could probably do up a reversing fan for about $3000, it would reverse pitch off of a timer and/or a toggle switch and clear the cores for you. If you are interested you might want to call our office in Edmonton and speak with James (780-930-6830 is his direct line) I think you'd be happy with our product.
