Kitchen Exhaust Fan in 12" wall?


Hi;
I need to replace the exhaust fan in my kitchen. It is through the wall, and the wall is 12" thick.
It looks to me that the person who installed the last unit fitted a standard sleeve into the wall, leaving a gap between the inner and outer sections.
I don't want to repeat this sloppy installation, but have not been able to locate a fan for a 12" wall.

The reason the wall is so thick is that we have a brick exterior on the house.

The diameter of the hole is standard 8-3/8.

I suppose I could buy a piece of 1/16" aluminum and form it to fit so that it overlaps the inner and outer pieces of the exhaust fan sleeve, then screw it to the sleeve. At least then I would have a continuous sleeve.

I think that the current installation (which was done about 30 years ago) had a piece of duct tape over the gap in the sleeve, but of course the tape has long since disintegrated.

Thanks

Just buy a small length of 8" duct and cut to length the size you need to connect the fan to the cover vent.
This is assuming the vent has an 8" piece to attach it to. If not, get the correct duct size and use that. You might have to increase the opening size.

I think that will work very nicely.
I was at Home Depot today browsing the plumbing aisle, looking at exactly what you recommended.
I'm not sure how short a piece of duct I can buy, but I can always cut it down.

Thanks
