Am researching these for the alfresco area to go over the BBQ

We will be doing a kitchen bbq area out there in the new home, as he have put a gas point, hot, cold water and waste point.

So will be needing a rangehood to try keep smoke to a minimum and not turning the ceiling black

 

anyone installed any or any recommendations for good quality ones with good air movement

John, Qasair will build you whatever you want - 1, 2 or 3 industrial spec motors.  We had one in our last house and it was unbeatable - solidly engineered and easy to install and dismantle if necessary.  The 2-motor Miele in the current house is a fragile, overly-complicated toy by comparison.

 

Being Aussie built, the finish can be a little "industrial" - but then that's exactly what you asked for! ;)

Edit - I forgot to mention, nothing in the domestic line came close to the air movement that could be achieved with a Qasair.

cheers for the link.

You are right, absolutely no point getting anything thats design for a domestic kitchen.

 

from what i have been reading you require around 2000cfm as minimum

Might be worth checking local council/state guidelines too. They can dictate position etc.

+ 1 for the qasiar. It'll be the only BBQ range hood you can stand next too while on and still have a conversation.

Hmmm - 2000 cubic feet per minute is a lot of airflow.  I think even a 3 motor Qasair is about 2,700 cubic metres per hour which converts to 1589 cubic feet per minute.  As a comparison, our 2 motor Miele was the most powerful one they made when we bought about 5 years ago and its absolute highest rating, which it can only achieve with optimal ducting and for a restricted time period, is 1300 cubic metres per hour which converts to 765 cubic feet per minute.

 

So, if you want more than the Qasair can achieve, you will need to go to a commercial ventilation specialist and have it made. It will be relatively ugly, noisy and expensive.

 

Hopefully, Qasair can offer a model that will suit.  It's hard to tell from their website which is still as unhelpful as it was when I last looked years ago.

 

BTW, the reason we didn't get a Qasair when we built about five years ago was that our builder suddenly needed an immediate answer on which rangehood we were getting and Harvey Norman had the TOTL Miele at an ex-display bargain price so we went with it,  It's had 2 new motors, one under warranty and one paid for by Miele ex-gracia out of warranty.  I wouldn't be surprised if it died tomorrow - I'd have a Qasair by preference in an instant, though Mrs M reckons the Miele is better finished, has easier to clean filters and looks nicer. :rolleyes:

Having recently built a new kitchen we spent a fair bit of time looking at good range hoods. Our criteria were:

 

Aussie made

Looks good

Good suction

Quiet

 

We ended up with a Schweigen with the motor mounted externally. So all we hear in the kitchen is the actual air flowing into the vent, not the motor doing it's nut. The motor is mounted on the roof with about 4-5m ducting to the rangehood.

That concept looks good, Jake.  I vaguely remember seeing these in the past, but I'd forgotten about them.  If and when the Miele dies, I'll certainly investigate this option.

 

I also can't help wondering if  the Miele unit could be gutted, a couple of Shweigen motors/fans  installed into the top of the ductwork and maybe even connected to the Miele control switches?  It would save removing the old unit that was a real pain to install.  Well, I'll look into that when I have to.

 

Thanks for the reminder. :thumb:

We did the same thing with a Quasair unit in a large room some years ago - the use of a rooftop motor pulling the air stream rather than motors mounted in the unit means you are less likely to be fighting turbulent exhaust flow. Very successful. Just a low thrum at full power. Most domestic units are severely underpowered and noisy by comparison.

You may find that the unit needs to be mounted fairly low with more disturbed air patterns that exist in an out door setting. Quasair are a Melbourne outfit and may be able to assist with advice re size power etc in such a setting. I would certainly be thinking in terms of commercial installers and advice. I suspect the average kitchen store will not be able to help.

+1 We have a Scheigen.....with dual motors on the room, brilliant and quiet

Make sure you have it cleaned regularly, the Stokehouse will tell you why.

 

Very important, though Schweigen "claim" the laminar flow of their design reduces the build up of flammable oils in the ductwork:

 

Turbulence causes soiled air to deposit greasy, smoky residues inside rangehoods and ducts, attracting vermin and insect pests, and creating a dangerous fire hazard – right over the cooker!

Schweigen’s Isodrive® system draws air quickly and freely to the outside with no obstructions to cause turbulence or any unhygienic, high-risk build-ups of grease and grime.

 

May all be marketing spin, but laminar rather than turbulent flow certainly reduces noise.
