Indoor/Outdoor Wall Exhaust IOW

Our indoor/outdoor wall exhaust requires a 30"x30" opening in the wall. It is supplied with a fully assembled indoor/outdoor air powered damper, and a fully assembled, shuttered and screened wall nozzle, with built in flashing. The damper can be closed entirely to prevent outdoor exhaust, or opened to allow as much as 30% exhaust. This option can be equipped on any Clean Shop prep station.
