Suppliers for ventilation
 
Hi, I've been reading up on proper ventilation but I cannot find info on suppliers. If someone could post some suggestions on where to find hoods, fans, or entire setups etc that would be very helpful.

Links to sites or pics of the parts needed would be great, I am not a very mechanical person.

Thanks in advance for any and all help!

Use the search this forum tool
Dale and Mike have posted a lot of information on vent systems over the years

here is some basic info
http://www.artglassanswers.com/forum...php?f=22&t=150
http://www.artglassanswers.com/forum...php?f=12&t=273




Right now this one is $500.00 http://www.rangehoodsinc.com/product...-Hood-5p93.htm

This is 350.00 http://www.rangehoodsinc.com/product...-Hood-3p28.htm

If you want to put one together
Squirrel cage fans check for used one at a local HVAC contractor
Stock water tank for hood

Hi David

Thank you for your response. I have read the 2 links you posted on artglassanswers but I was mostly interested in getting supplier info.

I have also opened the links you provided but for some reason my computer comes up with a warning each time that the site may infect my computer - it has done this in my earlier searches also so I have not attempted to enter the site :(

Would you have any other supplier recommendations? Also what is a squirrel cage fan? I did a search for this on Home Depot's site earlier and all it came up with was a squirrel have-a-heart trap :-k

Sorry for all the questions, I just want to make sure I get the correct set up- I have been at this way too long without proper ventilation.

Thanks David, those are what I was looking for. I will contact a local HVAC also to see if I can get a used one, or maybe have them make me a hood. You mentioned a stock water tank for a hood- where can I find this?

houptdavid 2011-01-13 6:02pm

Any farm supply store

Think you have a problem in your computer.....

Also there is not any real vendor that has a complete ventilation system available the meets glass work criteria other then the limited unit that Glascraft sells....

Dale

Donna J 2011-01-14 7:04pm

Thanks both for the help. I have done searches on the subject many times and have saved some info for reference but I'm still unclear on a few things. I know I'll need help from someone with expertise on this kind of thing but I just needed to know where to buy the supplies before I see about getting someone to set it up for me.

Thanks again, I know you must hate answering these questions again and again but I wasn't finding the info I was looking for.

RSimmons 2011-01-16 8:45am

Dale's right, there really isn't a one stop shop for ventilation. I like the GlassCraft hood but modified it a bit to suit my needs, then went to Grainger for the blower and HD for the duct work. The rest I built myself.

Hi Donna,
This is what I got for my system and where I got it:
Fan http://www.wamhomecenter.com/product...idproduct=5053
Ducting http://www.theductshop.com/shop/index.php
Vents http://www.luxurymetals.com/WallVents.html#anchor_335

Good luck

RSimmons 2011-01-16 6:28pm

The fan above is marginal at best. What torch are you using? How big is your hood?

Robert

Donna J 2011-01-16 6:31pm

Thanks for the links Flonce, I'll check them out.

I was at Home Depot today and found this:

http://www.homedepot.com/h_d1/N-5yc1...atalogId=10053

and this:

http://www.homedepot.com/Building-Ma...atalogId=10053


Would these work? The price is so low I'm thinking it won't but I thought I'd ask the experts...

thought not...

Air Volume (CFM) 472 at 0.0" static pressure, 440 at 0.2" static pressure, and 408 at 0.4" static pressure

440 CFM is marginal, in a 2'x30" hood you should have a minimum of 500cfm for a small torch.

That is why most range hoods do not work as they are generally less than this.

Flonche 2011-01-16 8:36pm

I don't have a hood, I have a funnel. Anyway, this is Donna's thread, mine is here and I'm going to put a picture in it right now so that you know how it's set up and why I think 440 CFM is enough.

RSimmons 2011-01-17 7:05am

Marginal as in not quite adequate to the task, especially with a hood. Hoods work better than funnels, IMHO, and need to be powered appropriately.

Robert

Dale M. 2011-01-17 8:02am

So far any fan listed here seems inadequate to me.... And thing labeled as duct booster fan and only lists its CFM at 210 in "free air" is not acceptable.... The 500 CFM rating in "booster fan mode" means nothing as you are not using it as a booster fan anyway.....

http://www.homedepot.com/h_d1/N-5yc1...atalogId=10053

There is not any proof that a funnel system will operate proper with less CFM than a conventional hood...

I would not consider anything under 500 cfm for a funnel system....

You have to remember with funnel system air draw (capture) is less efficient than any hood system... The suction or draw decreases dramatically for every couple of inched (in a radial pattern) as you get further away form funnel opening....

Dale

Donna J 2011-01-22 7:55am

I am considering buying this: 760cfm, 36 x 19, reasonable price considering it is for the hood and fan. Would this be sufficient? I would vent out a window that is approx 8' away using 2 turns:

http://www.amazon.com/gp/product/B00...A2N6FSQ1GAXHKE

I could vent out a window that is only 3' away but that window is only 8' from my fresh air intake (open door)- this would be too close, correct?

Thanks for any help, I really appreciate the time you folks put into keeping us all safe!

RSimmons 2011-01-22 8:19am

The hood itself looks nice but I think that the two turns are going to kill your drawing power with this unit (increased static pressure). The fan is rated to pull that much air in a straight run, turns will decrease that substantially. Eight feet is a bit too close to your exhaust port.

Robert

Donna J 2011-01-23 6:44am

Thanks Robert for the input. I could install it with 1 turn instead of 2, do you think the fan would be sufficient with 1?

I'm also looking at another one at a local outlet. It is a stainless steel hood, looks similar to the one in the picture I posted. Only problem is there isn't any info on the box re cfm's. I googled the name on the box and couldn't find any info, the store has no info on it either. The hood is $199. If I bought it and the fan isn't strong enough could I pull everything out of it and buy a squirrel cage fan or inline fan and install it in the hood? Is $199 a good price just for the hood?

RSimmons 2011-01-24 7:36am

Kitchen hood fans are, as a rule, not adequate for torch work. The stainless steel is nice, tough. I think that 8 inch duct from the hood is better than 6 inch - it'll be quieter with the same air flow. I'd buy the hood and add baffles to the back and sides, remove the fan that comes with it and invest in a good squirrel cage fan and ductwork to get it right the first time around. Don't buy anything that's described as a 'booster fan'. Revamping it after you find that the installed fan is inadequate will be a PITA. I spent a lot of time and effort assembling my ventilation system and it was worth every minute.

Robert

Donna J 2011-01-24 6:42pm

I have read that kitchen hoods aren't ideal but I thought that this style was preferred to capture the fumes and are ok as long as the cfm's of the fan is strong enough.

I haven't bought anything yet, still looking at all my options.

thanks very much for you help, I apprecitate it.

bshelle 2013-12-02 2:54pm

I'm resurrecting this thread because there are some good resources here - but wanted to ask if anyone has any recent information on purchasing an inline fan? I am upgrading my ventilation from the 'in the open window massive floor fan' to something I can use more comfortably in the winter months.

Thanks!

jhamilton117 2013-12-02 8:57pm

Check out hydroponics suppliers, they have moisture and gas rated fans for good prices

Roo Blaty 2014-01-09 1:30pm

If there is another thread or info please post link ;-)
 
Re-doing my studio and the vent system has GOT to be improved. At the moment it is soooo junk-yard-rigged-looking that I'm desperate!
(Please note I have NOT said something crazy like "Money is no object". \\:D/
I have only found this thread and this:
http://www.lampworketc.com/forums/sh...ht=ventilation

I like Dales idea! And I really want to ASK! :lol:

I have a fan and ductwork but now I'm wondering if I have the right kind of fan. I thought I just needed to exhaust the fumes? My fan pulls the smoke from the match when I light the torch...so I thought that would work?

Will one of these work better?

http://cheaphydroponics.com/store/ve...ns/cat_36.html

What IS a "gas rated fan" anyway? (Please don't be super technical). Can I get one at Lowes or Home Depot?

I would like a hood of some sort to mount on my table...is that possible?

Yes, I've been lampworking for years now and yes, it's pitiful that I'm just getting around to getting a proper set-up. But let's just be happy that I am getting one...8-[
