Pc Fan used to extract smoke - Any recommendations ?
 
I am going to sacrifice 120x120 mm of my overhead and back wall panels to some PC fans to extract smoke.

I have found the most silent, not a bad price at 14 UKP each, but i worry its not strong enough.

Its about 700 RPM..

NF-S12B ULN Ultra Low Noise 120mm Cooling Fan, 500/700 RPM

well if anyone has somthing to say about it i am all ears, if not, i will go with this one.

John,

remove smoke from where?

If this is to move room air it's useless - these fans can move air quite well through a computer case - however a computer case has little volume and a particular air path to cool critical components.

The fan has little capacity to move large volumes of air and no real capacity to overcome any sort of static pressure.......

They make fans for computers and fans for rooms for a reason - each has their job to do - and neither could do the job of the other well.

This is much like trying to hook a VW bug up to tow a 40' box trailer......... not going to go anywhere.....

I assume it's a one room studio? If not, why are you smoking in your studio ? At least have a dedicated smoking room.. Idk seems like a lot of work. Why not get a big fan and open the door to the outside?

UnderTow 3rd March 2012 06:06 PM

For all your fan needs: DC fans, AC Fans, ebm papst, cooling fans, blowers

There is a UK site too.

its an attic. Amazing flat bass responce here.. SERIOUSLY !!!

I smoke.. I can live with it. I have always... I dont produce for people, just my music so its cool. Got ventilation anyway.. Just want it over head and at the back sofa..

Its not that much work, Just need to cut out a quare in the Insulation and run a thin pipe leading the the vents i already have.. It will be insid ethe panels, behind the material..

Its just a little extra i will add.. I made these rough 3d images to... Gonna rock in reality.

Speaking Tube
 
How about a ship's speaking tube. A PC case fan should be able to handle that diameter of smoke flow.

ahhah love it,,, went to the Imperial war museum in london few days ago.. The Submarine section had load of them..

well yeah, i was thinking along those lines..fan into some funnel then a small pipe around the wall.. Attic's or LOFTS are wicked for this shit, any out of place pipe just adds to its Industial look,, Not sure if pcv counts though..

i dont really mind throwing and extra 50 UKP on this, I have not looked but these fans i am looking at are under 5 pounds each and 12cmx12cmx2cm

You think bathroom fans will be cheaper, as quiet and as small?

I would not imagine so, but i could be wrong. I guess i will either have to compromise on noise levels or power.

Uless i find the perfect match.

I will look into the bathroom vents though...

Rod Gervais 4th March 2012 01:04 AM

Bathroom fans are not known for being especially quiet........

The issue with the units you speak of is that they do not have enough power to overcome any sort of static pressure.......

They have no real power - you could take the tip of your little finger and stop them from turning by lightly touching the blade, and you'd hardly notice the contact.

Now, your thin pipe is going to create static pressure on the air moving through it - and when that static pressure reaches the limit of the fan it will keep turning - but stop pushing any more air - and it isn't going to take a whole lot of pipe to reach the limits of those fans. They simply are not made for the purpose you wish to use them for.

Believe me - if they did work we would be using them all over the place. They are cheap and quiet......... what's not to like if they worked?

Nothing specific, no. Paps make many of the fans for the "silent PC" brand names. (Remove the brand name sticker and oh surprise!) The good thing about the site is that you can just give the specs you want (noise level, air flow, voltage etc) and it will give you a list of possible candidates.

Good hunting!

Rod

yeah for sure. This is what i am thinking about..

The only way i was gonna get around it was by positioning them exactly where the smoke rises naturally so when it got to the panels it will at leats take something out the room.

I checked it with the lights off and a torch to see where it goes.

But i guess the pipe thing will be another problem..

WELL, this is why i post here, to get sound advise. I have one day to research about static pressure, tomorrow it all arrives and building will start, unless i find a way to KNOW it will have an effect thats worth it, i will not do it.

I will also look at the site for the computer fans and put the numbers again what i can find for static pressure.

I just found a site for all types of fans from Industrial to domestic.. Tones of products.

Elta Fans: Products - Building Services

they actually list SPL for specific frequencies.. (never expected that).. like this:

Elta Select - ATEX - Raptor SFB

I am now going look into the idea of having a very strong fan in the wall that sucks from the air out and just the pipes going to the panels .. To be clear, i was planning to have the PC fans iN the panels sucking the air in and than pushing it OUT of the room..

Gonna give the company a call and see what they recomend..If anything..

Sounds like what you're looking for is something based around a fume hood.

There's always another solution. Chimneys don't need fans, you just make it higher than the roofline to create the draw.

Also if you can manage to vape instead of smoke you might not need it. Electronic cigs rock. Here's a non-commercial forum dedicated to them. E-Cigarette Forum

Actually there are 2 columns which are chimneys. But not positioned for what I need.

Sureley a chimney with pipes leading to my panels could never draw the smoke out..I would need to be hot.

Also anytime anyone lights a fire in the winter there is a risk if it coming into my studio. Jesus , I dont want to imagine.

I am looking at a way , if i cant afford the quiet fans to make a box around it..

Doing some reading now.

Buy an air purifier with an activated carbon component.

Most aren't quiet enough to run while tracking (or mixing) but you can turn it on to suck out the smoke during down time.

I have a beast in my paint studio for taking out paint thinner and other fumes... it has an 18-pound carbon bed. but you don't need anything anywhere near that robust.

Another cool option, thanx man.. how much they going for? How much you paid for yours?

AwwDeOhh 5th March 2012 10:09 PM

Mine is the kind used in those nail-painting stores, and in art studios. They go for around 600-900 USD.
I got one of the 5000 series
Air Purifiers Indoor air filtration systems with activated carbon, HEPA, UV by AllerAir

But looking, i noticed they have a smaller one called the "air tube" w/7lb carbon bed for around $300
Air Tube

There are other makers (alot of air purifiers will have a "Carbon Pre-filter".. these won't do so much to take out VOCs)

Take smoke breaks, walk outside, go to another room............
It helps clear your head and your ears too.

Maybe one of the smokeless cigs for when your in the room.

Really......you'll feel better coming in, working and hanging in your room without the smoke and smell..............

How about looking into an Air Multiplier or so called fanless fan (btw, there are other manufacturers than expensive Dyson!)

kasmira 6th March 2012 06:20 PM

Dyson's air multipliers are ****ing awesome.

You could buy quite a few cartons of cigs and smoke your brains out ......out of the room.........for what you may be paying for a fan and what ever to install it............jkthtyrt
