I think the rep should be the one answering your questions I see these on Wayfair maybe check there to get mor einfo. I use vent-a-hood most of the time tried and true .

Is this the SU109? You didn't specify. Sirius' website fails to provide dimensional data. Be sure that the baffle space overlaps your cooking zone side-to-side and front-to-back. Read hood threads here to gain perspective about what is needed for capture and containment. Read MUA threads here for what is needed for make-up air, which you will likely need as a deliberate system in most of the USA.

I as just to ask the same question. I can’t find any reviews about the Sirius hood in your picture. Looks like the Pro line but is it the SU109 or SUTC35?
Both are 1,100 CFM with a noise level of 66 decibel or 5 sones…. I have no clue whether that’s noisy or not? Apparently 50 decibel is considered quite with 5 or less sones, but how come these Sirius hoods have a noise level of 5.1 sones only at a 66 decibel? Hope it someone who has these hoods can chime in? Thanks.
