How clean should a range hood be- Best Hood Blues
Comments (1)Just because a hood is sucking in air...and grease, doesn't mean it will all get sucked out. Grease is heavier than air and will cling. Better the grease is on the hood than all over your kitchen. It does require regular cleaning....See MoreWill a 1200 CFM blower be just as effective in 63" hood vs a 48" hood?
Comments (15)Unfortunately, most wall ovens do not have their own vent interfaces. What I did was put a pair of registers in the ceiling over the ovens, with their connecting ducts joined in a Y-adapter, and the output duct connected to a roof blower. The blower was a re-purposed NuTone down-blast roof blower purchased many years earlier to provide a boost to the vent of a Litton "kitchen center." The register boxes take (IIRC) 12 x 14 furnace filters to help keep grease particles from the ducts. Note that not even a commercial "eye-brow" hood will capture the smoke escaping a broiling oven when the door is opened. What these registers do is help pull effluent from the ceiling area and slowly clear the kitchen in concert with the main hood. The only way to successfully deal with opened ovens is a large hood right over them, or a commercial porous ceiling ventilation system, such as illustrated here: http://www.kitchen-ventilation.co.uk/heydal Yes, the MUA now becomes more complex because the control has to be "closed-loop" instead of "open-loop" and thus needs a servo control system to control an even larger MUA blower. My kitchen blowers' combined output is 2500 CFM (zero static pressure rating), and likely pull a total of 1500 CFM when there is sufficient MUA. With both blowers having variable control, the actual CFM can be anything, windows can be open or not, bathroom fans can run or not, etc., so the scheme is to control on differential pressure between my kitchen and the vented attic. Not all parts of this system have been purchased and integrated. My excuse is that my honey-do list is very long and keeps expanding. Items in place: Roof down-blast housing on pedestal for air intake interface with attic Hydronic heat exchanger in attic with its separate control loop to my furnace (functioning) 3-ft square diffuser in hallway facing kitchen Sensing system installed Control system components mounted in basement; Fuji computer purchased but not yet incorporated Key elements yet to be obtained (mostly from Fantech, I expect) Big axial blower sufficient to flow around 1500 CFM through the pressure losses of the ducting, air filter, and heat exchanger. It also has to fit through the attic access stairway. Current-loop control fan motor driver Pleated air filter box Damper Various sheet metal interface sections I should add that my only combustion appliance is a blown oil burner that has its own sealed MUA supply, so delay in completing this kitchen MUA system is an annoyance, but not a hazard. In your case, a carbon monoxide warning sensor is suggested. kas...See MoreNeed Quiet and Effective Hood Liner for 59.25" Lacanche Range
Comments (11)Joe Blow-You will love your Modern Aire hood. We have a 42" 1200 cfm hood over our LaCanche Volnay and it's fantastic. Ours vents directly out the back through a 6" wall. The fan and motor aren't loud at all. We use it almost exclusively at it's lowest setting, unless searing or cooking stir fry. I've never used it at 1200 cfm. It does get loud at higher settings, but it's the movement of the air, not the machine making the noise and there's no getting away from that. One thing I will caution you on. I have propped up one of the metal "fillers" next to the baffles (there's one on each side) with a small piece of wood because it makes a whistling noise if I don't. I never called Modern Aire about it to find out a better solution or why this is happening but you might want to mention it. Despite that, I love the hood and am putting one in my new beach house kitchen this year. I especially like the infinitely variable speed and light controls and how easy it is to remove the baffles to clean them in the DW....See MoreHow effective is the Miele slide-out range hood DA 3480?
Comments (4)Start with a mental image of a commercial hood. It will be the most efficient means of capturing and containing cooking plumes that will be rising and expanding from the pan surfaces. Now start modifying the image toward simple residential hoods. Each stage of modification means giving something up, whether it is power efficiency (maybe not important), containment efficiency, or capture efficiency. (Flame barrier will probably be OK with almost any design.) The best one can do with a residential style hood (fits under an eight-foot ceiling) is overlap the cooking zone by enough, use baffles with some volume below them, have enough CFM, have enough make-up air to achieve the CFM....See Morerossn
