Kool-a-matic fan replacement
Recent experience in Q and Senator's Wash in California, while boondocking in warm weather, re-established the need for a 12V, whole-house exhaust fan. My Kool-a-matic fan motor needs to be reconditioned, but no reliable shop has been found.

A number of owners have recently replaced their generator radiator squirrel-cage fans with 12V flat electric units usually found in compact cars. The throat of the Kool-a-matic fan is ~12 inches on my coach. I have found 10" diameter flat fans rated at 650 cfm @ 5.3A, to 950 cfm @ 7.9A costing from $60-$110.

The Kool-a-matic motor is about 1/10 hp, therefore around 8 A. I haven't found a published flow rate, for comparison.

Anyone try this? Other suggestions?

Thanks--
