Is an in-line blower for hood a bad idea, mounted in the kitchen?
Comments (10)many many many makes out there. Go to an ecommerce site and use key words like blower, insert, power-pack, and liner (although i always thought liners were just the thin layer of steel lining a chimney, it is a useful term and it appears to mean the motor too.) Congratulations on getting a massive hood. I think it is a great find. I'll ask you a few questions, in reverse order. What dimensions is the opening at the top of the hood? Rectangular or round? Do you know what an adaptor or transition is in terms of ducting? What duct size would you think you want to install? Before that, the big question is the quantity of air (CFM) you expect to blow. Before that, the kind of cooking you do, and whether it's for one, for two, or for a whole restaurant size crowd (i.e. many burners on high, and often). Since you have complete access to your future duct, an inline motor is an option. A good option. There is no advantage to "inserting" the motor into the hood, compared to having the motor be positioned in the duct (inline) or even outdoors on the outside wall. J, you have a good sense of what is needed. First you got a "sump" (the collector / hood / canopy / umbrella) and now you want a blower. Makes sense to me. When I list a bunch of terms as if they were synonyms, it helps you search later. Don't take any term too seriously. Below is a link to another thread where I may have confused the woman who posted her query. Too many terms.

Comments (5)Internal Motor Range Hoods have blowers mounted inside the hood. The range hood cover, the blower motor, baffle filters, fan controls and lighting all come in one unit. Pros It is easier to install and access the internal motor. Cons Large CFM internal blowers tend to be noisier than the other types. Remote Blower Motor is located outside of the range hood. You can either mount the blower outside of the house,on an outside wall /on the roof, or you can place it inside the house, in the attic. Pros They usually has high-efficiency output,ranging from 800 to 1200 CFM rating. You can also benefit from its quiet operation since the blower is located outside of the hood,and not inside the kitchen. Cons Installing a remote blower is a new trending and it might takes more time and effort for labor to install the blower....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 Moreelbow immediatly after inline blower? (Range hood)
Comments (15)are the 45s you are referring to 45s....or 90s adjusted to be 45s? I went to the HVAC supply today and they didnt stock 10" 45s so I grabbed a couple 90s...which can be adjusted to be 45. This will definitely be a more gradual sweeping corner (but take up a lot more space). I think I can do one of these corners (2 90s adjusted to be 45 each forming one big 90 corner) from the vertical duct to the blower, but I wont have enough room to do a big sweeping corner to to the wall vent...ill prob wind up putting a single 90 there right out the wall. I think that will be fine...minimal resistance in the (relatively) longer run from the hood to the blower, and then a tight 90 after the blower but that 90 is the *only* duct between the blower and the sweet open air. I guess when I take a step back, the only reason I am doing this is in hopes that the 90 between the blower and the hood will reduce noise a little (as opposed to having a straight duct between hood and blower). I suppose I have nothing to lose and its only an extra 20 bucks in parts. One other question for anyone who has used the fantech blower....I bought the rubber clamps they sell for either side of it. Does the duct not attach to the blower in a male-female manner (pieces of duct do with one another)? does the rubber gasket clamp onto the blower, and then onto the duct so that the metal from the blower than the metal from the duct do not make contact (thus limiting vibrations being transferred to duct work)? I havent studied the clamps (or the blower) yet but in my mind that would make sense....and if its not setup like that, and there is a male-female screw+tape attachment between the blower and the duct...i dont know what the purpose of those rubber clamps would be :)...See Moreal diego
