will a silencer help my hood?
Comments (4)It would help if you could specify the space available for ducting and potential silencer. The Fantech silencer for a 10 inch duct is 14 inches in diamter and almost three feet long. The 1100 cfm inline blower is quite bulky also and requires inlet and outlet transitions. You might be better off hanging a remote on the side of the house if it's not in plain view. However, short duct runs with remote blowers can be noisy according to Wolf's literature (Wolf and Broan appear to use the same inline and remote blowers). In that case the silencer would probably help. Since you will be venting out the wall that implies a 90 deg turn for a top discharge hood. If that's the configuration you have you should run at least several feet of straight ducting before the 90 deg bend....See MoreSound or Silence?
Comments (44)Snidely -- Guess I'll have to ask another 'Math Brain' about the music thing! Your answer about preferring a 'predictable tempo' does seem to go along with what I'd thought, though. I may have listened to too many classical pieces. Now I find myself getting weary of predictable repetition, regardless of a change in key, tempo, or instrumentation. It is amazing that we humans still like music composed ages ago. I only took one music appreciation course in college. The professor found it quite remarkable that humans would love a sound that came from vibrating a piece of cat gut. Attention getting!...See MoreHelp! Will silencer or inline blower work for my vent hood setup???
Comments (14)Not sure where all these comments are coming from, but I thought I would just add my opinion to the mix. You will want to consult with the manufacture of your blower what their limits are regarding length of the duct for a given diameter (in your case 10"). The manufacture will give you a length, which should be representative of what kind of head losses that blower is capable of working against to meet it's rated flow capacity. Most quality blowers I've see on the market will be rated at least around 50 feet of 10" duct. Looks like your setup, with 3 90 degree bends, and 19 feet of straight ducting, sits right around 50 feet. My nonprofessional opinion is you are fine....See MoreIn-line silencer placement question for range hood
Comments (6)True, but only if the mesh area does not choke the 1000 CFM blower to be barely better than a 600 CFM blower. This will depend on their relative fan curves. I am only here to aid in achieving the performance that is desirable from hood systems over the full spectrum of potential cooking activities. You are welcome to let aesthetics dominate your trade space. Most 'pro-style' hoods have baffles. Although the Wolf Design guide lacks imagery of the guts of their hoods, I think most of the higher flow ones have baffles. My Wolf hood is shown below. It hangs from an 8-ft ceiling via a 6-inch extension. While much longer than you need, and an island hood as well, it illustrates what can be done in an 18-inch height hood. Modernaire, Prestige, Abbaka, and many others surely have baffled hoods with some volume below the baffles that can be fitted to your architecture. If your ceiling is only 7 feet high, then a lower profile hood may be desirable if you want the hood base above 30 inches. Baffles with some slope should still be possible....See More- 4 years agolast modified: 4 years agoamylou321 thanked raee_gw zone 5b-6a Ohio
