94pt 'cool o matic' gally exhaust fan

[Rob Robinson]

I have a Fantastic Fan in the bathroom and it works well. However, my Koolmatic in the kitchen has enough suck to remove the chrome off the stove knobs. For me the best system is having both fan types. To overcome the problem of difficult cleaning of the Koolmatic vent vanes I removed the vanes completely and just use the sliding panel to close up the well when not needed. This also has the benefit of giving you access to the variable speed control so that you have a three speed Koolmatic instead of a single speed. Happy now Greg?

The Fantastic Fan as a replacement makes sense ... but I like the
cool-o-matic because it allows me to run the fan (and get
ventilation) even if its raining.

Does anyone have info about "Maxxaire" or other alternatives that

might allow all-weather use of the fan?

Note, my cool-o-matic quit a few days ago. I'm not sure if it's the
thermostat or the fan itself -- or a fuse (anybody know where the
fuse is?). (I don't know when I'll have time to do a full trouble-

shooting on the fan while we're on the road...)
