Best low profile vent hood? minimum 600cfm?
Comments (4)I've been very pleased with Vent-A-Hood. It works extremely well and is as quiet as you'll find, unless you go with a remote blower of some sort. That being said, we planned for an optimal installation. The ducting goes straight up through the attic (less than ten feet). No turns, and terminates in a properly-sized roof jack per Vent-A-Hood specifications. My current system was installed in 2005. I think that that in quite a few cases, the source of dissatisfaction by some owners has more to do with complicated installations, involving several turns in the ducting, long duct runs, or constriction at the roof jack. I cannot over-emphasize the importance of a proper roof jack. The system in my kitchen operates flawlessly and is very quiet. Even when turned on full speed, it doesn't interfere with conversation or require the television to be turned up to a higher than normal volume. Most of the time, I run at the very lowest Sensasource speed setting. Even then, nothing escapes it. I know this because I have recessed can lights throughout the kitchen, and if I had smoke or air-borne grease flying around, I'd be able to see it in the beams of downward light from the cans. As for your installation, I think that if you can forego cupboards above the hood, it would probably make more sense to go with one of the wall-mounted or chimney-style hoods. Matching shrouding is available to hide ducting on the wall-mount models. Look for a model that can be ordered in 27" depth. You'll need the extra depth over a commercial style range. Far more important than a strong blower is a large capture area. Having a range hood that extends beyond the the perimeter of the cooktop will allow you to capture more with the blower running at a lower speed. You should definitely try to install a hood at least 6" wider (3" on each side) than your cooktop, and one that extends out to the front of the burner area, If you have room to go with an even wider hood, that's even better. My range hood is 12" wider than the cooktop and extends out to the cooktop leading edge. Other manufacturers make hoods in similar dimensions, but I like Vent-A-Hood and recommend it. I've been entirely pleased. The important thing is capture area. The larger the hood, the more you'll capture, and the fewer cfm's required. Keep in mind, if you air condition in the summer and heat during the winter, all that air you're exhausting you've paid to cool or heat.

Comments (1)Something like this might work for you-- http://www.prolinerangehoods.com/index.php?main_page=product_info&cPath=31_41&products_id=76 Check out the rest of their island hoods as well....See MoreAbsurdly Low Ceiling and Kitchen Fan/Hood
Comments (3)Drilling through structural joists for anything larger than a small pipe (and then only near the end of a joist in the center of the beam) is out of the question. Forget it for ventilation sized ducts. Your duct would have to be either rising through a convenient closet on the next floor or scabbed to a wall on the next floor (if the location allowed) or be horizontal across the kitchen ceiling. I think we need more layout info before making a pile of guesses. While round ducts are the most efficient, this is slight, and rectangular ducts that fit through studs or between joists are useful. Maybe you can go along the joists to a wall, drop down several inches, and then follow a soffit under the joists to the outside. Find a standard rectangular duct size that has the same area l x w as the circular duct area pi/4 x d^2 recommended for your selected hood. Sometimes ceiling ducts can be hidden in cabinets hung from the ceiling that provide some added storage. To avoid head bumping, set the hood at head clearance height and make the aperture overlap of the cooking surface larger, such as 4 inches all around instead of the typical 3 inches all around. kas...See MoreHelp!

Comments (1)No 4” ducted hoods. 6” is where it starts. 4” is a dryer duct, not a hood. You will need to enlarge your ducting. Rigid metal ducting ONLY....See Morebreezygirl
11 years agoMy ceilings are about 91.5". I scored this Rangecraft Viser hood on clearance from the manufacturer. I had to have the duct cover portion (its all one piece) cut down to fit.
I don't know that you are necessarily limited to 10-12". Guess I don't understand that.

11 years agoHola,
Anyone have pictures of their hood duct work? I may not be fully understanding this ducting business...OR who do I contact to custom fit a custom venting system into my 42" antique copper hood shell?
Because of the front curve of the copper hood, a standard hood liner doesn't fit in. I've been talking w/ Mark of Tradewind and he's got his engineers brainstorming.
Sorry, I didn't mention that my hood = 42" wide.
Sparklingwater: thanks for the suggestion, but w/ quick research, I only found 30", 36" or 48".Breezy: Beautiful hood and kitchen!!!
You wouldn't have a picture of the duct work w/out the duct cover on, yes?My hood vents up and then bangs 90degree to left to go outside the house.
Thus I need this transition piece, to go into the elbow piece:
so transition = 7" tall + elbow ~9" tall = 16".
Since I have 26" from ceiling to bottom of hood, 26-16 leaves me 10" for the hood height.
thank you very much for your help,

11 years agoOur ceilings are 90". Here is our math:
90" ceiling height - 37" base - 30" minimum clearance =
23" high hood.Here's how it breaks down: 37" for base cabs and counter (34 1/2" cab, 1 1/4" granite + 1 1/8" for the grates (Wolf gas rangetop) = 36 7/8" round up to 37".
Wolf says the hood should be mounted 30 to 36" from the cooktop. I was nervous about making it that tight so instead of using all 23" remaining for the hood, I ordered the Modernaire to be 21" high, which puts us at 32" above the grates, well within code in our town.
Note that we almost had to lower it today 1 3/4" because the garage on the other side of this wall has a lower ceiling and the opening of the hood is so near the very top of the hood.
Advice - figure out how it will vent and where that ductwork needs to go BEFORE you buy a hood. I was very nervous today, but the sheet metal guy built a transition from the hood opening in the back to meet the eventual duct run in the garage. Whew!
Minimum clearance req'd is 30".
