1.) Looks like a Wolf/Viking type hood - there are several manufacturers who make the "angled box" style hoods.

2.) Considering it's on an outside wall, it would be a crime NOT to duct it out :)

There are many advantages of ducted range hoods vs ductless - better performance, lower noise, no need to change the charcoal filters on a regular basis. More info: http://www.futurofuturo.com/rangehood-FAQ-10-reasons-to-have-a-range-hood.php

Thank you very much for your response! I'll definitely check our wolf/viking for options.

The hood that I need is for a condominium apartment building. The present range hood is not ducted to the exterior, and I am not allowed to renovate the exterior of the building to add an exhaust penetration. So, in this instance, I am stuck with a recirculating type of hood. I am also restricted with the height clearance (I only have 7'-0" cleat to the u/s of a bulkhead).

Any other suggestions would be most appreciated.

j2muller, thanks for another question! We reused the client's range hood, purchased about 7 or 8 years ago: a 30" Jenn Air JXU9130 WP. It has served this family well. LInk here:
