Thread: Noisy domestic kitchen range hoods

John

Look at the Qasair rangehoods at Winning Appliances. Very Quiet and resonably expensive - All up ours was about 3.5K but worth every cent

As mentioned QASAIR are brilliant, but exxie - you can remotely mount the fan units in rangehoods provided you're willing to do or pay for some fabrication and messing around with your existing unit. Personally I haven't had to do it yet but will be this year when I build our kitchen. I will not be modifying our existing piece of crapola though .... I have bought several extraction systems for our kitchen. All except one of them has remotely mounted fan units.

The one we are using for the soups/pastas area is one of those half-round (conical I guess) units with the fan inside .... I will be removing the fan and ducting it up through the roof or out the side of the building.... not sure which, yet. Will be a fun project.

BTW the other units are Gaggenau underbench extractors and a SMEG unit that rises up from behind the appliances when turned on, extracting the fumes under the bench also..... it's a big kitchen, designed to be used for photography and promotion as well as over-eating.

I reckon best thing to do is buy the style of canopy/ extractor you want then rip out the guts leave in the filters, put a exhauts kit through into the ceilin and some where along the duct add an inline extractor (200 dia 500 l/h) all linked up to the switched in the canopy. if you put the fan far enough away you will only hear the air movement, and should come in well under 1000 bucks with a few bits left over to find a use for(did ours for 400 all up).The extractor we had made too much noise also and not enough suction so i started to look at changing it, works great.(theres still noise just no where near as bad and only air movement) give it a go.

I used to work for a stove manufacturer in England, and the bulk of the problems they had with noisy extractors were due to issues with the ducting, not the motor. Basically they sold high volume fans, but installers would often ignore official advice and use standard ducting, or use long runs or too many bends.

So maybe you should have a look at putting in larger ducting, or shortening or simplifying the runs.
