Kool O Matic Exhaust fan

With out success I have scoured the net for info on the fan in our MH
I specially need the amp hours/watts.
We are going dry camping and need night air movement
Don't want to run it all night even on low and have our batteries exhausted

I had to replace my Kool A Matic last winter. They've been out of business since '06 and all parts were long since gone. In looking for a reasonable replacement I discovered that they were pretty good at moving air. Their power rating was 7.5 amps on high. I saw several owners who claimed a real world power usage of around 6 amps on high.

Or go home- built.

Our old coach has an overhead fan above central kitchen that either blows out or in and is temperature controlled but draws lots of power.

Google high CFM low amp fans and you may find what we did.

We found some of the 4 or 5 inch size rated very high CFM at only .5 amps.

They were equipment harvest so the 80 buck retail units were only 5 each.

Mounted 4 in the vent to pull in air and it works real well and since under cover looks stock.

More air than original with only 2 amps.

Also made these that will run for 5 or so hours from same fans.

What is your experience when buying a ceiling fan. Can you share? And what is the best price do you suggest?
Thanks.

Kevin, you asked about ceiling fans; I just installed ours. It's from Global Products, from Amazon. Go to Amazon and search for RV Fans.


This one is a 42" bi-directional multispeed unit with a remote. About $130.


Works really well, and draws only one amp at 12VDC. (I gave not verified that, though).


Tom
