Ca. 2007 Mono commercial vent hood with duct and blower. We don't have the proper adapter for the plug, so this is sold untested. According to our supplier, it was up and running prior to coming here. This was originally paired with a deck oven, so it doesn't have the typical filters you'd expect of a vent hood and may require a bit of creativity to get it working for your space. Regardless, this would be a good start for someone setting up a kitchen or perhaps a glass blowing shop. Dimensions listed are for the hood. The duct / fan situation measures 21.25"W x 45.5"D x 16.5"H.
