Owner had a vent fan in their kitchen… a fan in the wall behind the stove about 48″ off the floor, with an outlet that ran straight out the back and into the garage. She removed this fan when she realized that it was encrusted with 20 or 30 years worth of gunk.
The cabinets are not being modified and she wants to replace the fan with something that uses the same location in the wall. Ideally this would vent vertically up thru the wall and into the attic, where I can get it outside at a gable. Problem is, I’ve never seen anything specifically for this… installed about a million typical vent-a-hoods and hood liners but not much else.
So, I’m imagining… what… a wall-mounted grille with a clean-able filter behind it and an attic mounted blower. Or something like that.
Anyone know of anything that might work in this situation?

The garage floors and walls must be lovely--not to mention her car--with nice coatings of grease! Don't have any good answers for you, but was wondering if you could install a bathroom vent fan? I don't know if they can be mounted in a wall instead of ceiling, but don't see why not.
Check Broan, Vent-a-hood, etc. I want to remember that one of those has an under-cabinet with a remote fan unit.
Your real issue will likely be length of duct run, followed by proximity to operable windows.
HI David,
Howz the San Juans?
I did this recently with a inline fan located in the attic. I had my HVAC company install. They are going to get back to me with the type of fan they used.
I ordered a commercial style grease filter (aluminum) from Katom Restaurant Supply @ http://www.katom.com/c-EQUFA1.html. Then I asked the HVAC company to fabricate a stainless steel channel, mitered at the corners just bigger then the grill size. On one side they created a hinged flap that allows the grease trap to be removed for cleaning.
Works great, very clean look. Customers had a down draft with large gas grill and felt that the downdraft was stealing the cooking heat. Cooktop was on a island and they did not want a hood to ruin line of sight. So far they seem happy with the result. Installation was in January 2005.
What type of CFM are you trying to move?

You have a couple options. 1 is a small roof mounted exhaust fan, very typical in commercial applications, but somewhat unsightly. Some of the "premium" residential equipment manufacturers, such as Viking, offer them as well. 2 - is an in-line "cabinet" fan. These are just a blower in sheet metal box. Broan makes them and they are available through Grainger and any HVAC supply house. One capable of 200 cfm @ 0.5" would cost about $175 - $200.
