I have a 4 year old 1/4 hp Pacific Coast chiller for sale. The fan needs to be replaced and you can purchase the fan unit direct from the manufacturer in the US. I believe the cost for the replacement fan was around $50.00 (US). Since the fan broke, I used a regular portable fan to cool the unit and it worked fine.
This is the exact unit.
