I'm considering a Wolf Insert/Liner in a 42in custom wood hood, but I can't seem to find any information regarding their blowers. I'll most likely have to use an internal fan due to a lack of attic height and my appliance person doesn't have much information regarding the Wolf blowers. I'll need something in the 600 to 1000 cfm range. Any idea who makes their internal blowers and the specs (mainly cfms and decibels)?

Thanks.
