I am looking for an overhead ventilation system to accommodate a wolf 48" dual fuel range. Based on the current design, the system would be inside a chimney box (not sure yet what the material would be). Iknow that wolf makes a hood liner and blower

�Wolf 48" custom hood liner:

PL462212

Wolf 1200 CFM interior blower:

814423

Has anyone had any experiences with these models? Can anyone recommend a less expensive yet comparable alternative?
