Panasonic Whisper Fan Carbon Scrubber Tutorial: Quietest most efficient fan ever!

[Muleskinner]

Here is another excellent choice for low noise - Fantech FG 4 inline fan:

http://www.hvacquick.com/products/r...ans/Fantech-FG-Series-Inline-Centrifugal-Fans

This moves 135 cfm for only 20 watts of electricty, with both ends attached to ducting it's nearly silent. You can get a speed adjuster to lower it down to make it even quieter.

I used these to exhaust/filter the closets in my apt. and you could stand right next to the door and hear nothing. These are exceptional fans, super efficient. smaller and quieter motors than most 4 inch fans incl. Vortex.

For example, the Vortex 4 inch fan draws 80 watts instead of the Fantech's 20, so the motor's bigger and louder. To draw 20 watts and move 135 cfm is VERY efficient, Fantech rocks.

Hi there I took a look at the link you posted and was wondering if you could post a few pictures and or explain in simplified terms what I need to make this work.

I would only need the lowest cfm fan so would I just need a small 4inch can filter and some clamps.

Also do I need to buy a power cord for it and know how to wire it up?

I was thinking about rigging the Panasonic one up like the guy a post or two above yours since it looks pretty easy assuming the fan you mentioned is not easy for a beginner.

Hi Bueno time I like that setup you got there I just have a few questions about your method.

I noticed you have a big ass carbon filter on there and your tent is not big at all.

Do I need one so big or can I use a 4inch small can filter you can get from most supply sites?

Also about the fan itself do you just wire up the cord that comes with it strap the carbon filter onto the out take and let her rip (after taping the open bits to block dust etc)?

Being a noob and having a space as small as yours I want the smallest filter possible and should I get the same model as you or are there slightly newer better models I can make this work with?

Did you get any answer about the Muleskinner 20watts fan/filter setup??

Thanks!

 

[catrinfachenda]

Can you give us more details, I was also digging the Panasonic setup or a Can 705 filter + a PC fan, but for 20 watts I would prefer a proper setup, what size of filter would you go with that Fantech fan for a small cabinet grow (size of a mini fidg)

Thanks man!!!

Hey guys...Longtime lurker, first time poster....I custom did a cabinet from Home Depot....It's roughly 6'h x 4'w x 20"d.....I am going to have 32 cfls (23 to 26watt) plus four T5HOs in the flowering chamber...

I have the 80 CFM Panasonic whisper ceiling fan in there...I have two passive intakes that are 2" diameter each....I also have two 2"pvc pipe that go into the top sealed chamber where the fan is....

I just ran a test with only 22 cfls in only the flowering chamber (that are 2 vegg chambers), and temps are around 100 degrees.....

Outside room temp was 63 degrees to start (basement)

I have made sure all the seals in the cab are good so that it is only pulling in from the exhaust...

I thought I read somewhere the exhaust pipe should be 3x the length of the exhaust diameter ?

Any ideas as what I should do to cool this thing ?

Longer exhaust pipe ? More intakes ? An active intake ?

thanks guys, glad to be a part of the forum here.

 

[Tonygreen]

More passive intake should help alot.

 

[SpaaaceCowboy]

More passive intake should help alot.

from what I have read is you want to double the size of your intake vs the outtake..

So since it is a 4" exhaust, I was thinking two more 2" intakes....

The question is....The floor for the veg chamber is only about 20" x 12" and that has one 2" intake.....the floor for the flowering chamber is about 25" x 20"....Should I cut the two new intakes in the flowering chamber rather than one new intake in the veg, and one new intake in the flowering ?

 

[Tonygreen]

Deffo two in the flower chamber,

 

[SpaaaceCowboy]

Thanks Tony, I think I'll roll with your idea, and cut two new holes in the floor of the flowering chamber.

 

[SpaaaceCowboy]

Ok now I guess I am not cutting more holes...at least not anymore in volume...I just found out that the intakes should be larger than the outtake....2:1

So why would I make more intakes ???

I m going to do all new pvc holes

 

[SpaaaceCowboy]

sorry can't edit posts yet....

OK well I think What I am going to try at this point is to do all new holes.....Cover up the existing at start anew....

HERE'S THE PLAN:

Exhaust diameter is 4"....

So I was thinking of going with a 1" hole in the top of the vegg chambers, and a 1" hole in the top of the flower chamber.....then I would put a 1" hole in the floor of the vegg chamber, and a 1" hole in the floor of the flower chamber....

Anyone think this might work a lot better ?

 

[SpaaaceCowboy]

Disregard above questions pls I've moved on....I know someone was saying something about .25 static pressure or something....I've noticed the panasonic lineup varies...

Can anyone chime in here ? I am using a 80 cfm but that might not be enough...I am considering going to the 150 cfm

[Tonygreen]

That is the one drawback is they dont have as much sp. Depends on your filter but I went one bigger than i thought would be good too and no regrets.

 

[wantaknow]

man I needed this ,building a small cab to chunk in ,sweet!

Tony, what are the dimensions of your cab ? And what cfm is your fan ? Do you also have a Whisper Ceiling model ?

 

[SpaaaceCowboy]

I'm considering going balls out and getting the 290 cfm...that sum bich has to keep my cab cool

http://www2.panasonic.com/webapp/wc...roupId=119507&surfModel=FV-30VQ3&displayTab=F

anyone using this model ?

 

[SpaaaceCowboy]

well since the whole idea was to keep my cabinet stealth I am going to stick with one of the quietest whisperceiling fans...The 150cfm...I am hoping this will be enough to also cool my flower chamber...flower chamber is roughly 3'w X 5'h X 20"d....Anyone think this will do ?

Is anybody out there ? This thread used to be so alive now it's a ghost town. Would love to hear from someone who uses one of these fans for both odor control and cooling. thanks, SC

here's some pics of the cab...the left side has a top and bottom vegg chamber...those chambers have no ventilation right now...

The flower chamber has the 80 cfm whisperceiling in there...I have that chamber setup for a total of 28 cfl light sockets...However, because the 80 cfm can't suck that good I can only use about half that number before temps get too high....I really wanted to keep it stealth as that 150 cfm is around .3 sones...If I jump up to the 190 cfm the sound goes to 1.3 sones....Not sure how loud that would be.....I'm just thinking flower chamber is roughly 22 cf...should not a 150 cfm fan cool it ??? thanks again guys.

Hello!

I built my scrubber using the Panasonic model FV-10VS1. It is rated at 100 CFM. It does the job nicely, no obvious odors until very late in flower and those odors are easily masked with some Glade Plug Ins. I get good negative pressure in my 24" X 24" X 64" tent. I have been using this set up for over a year, no complaints.

I also have a tip that I came up for for making carbon changing much easier in this type of setup. I put my loose carbon in a *micro* mesh lingerie bag. You have to use a micro mesh bag so the carbon doesn't fall out (obviously). You can then spread the carbon around as needed inside the mesh bag, and airflow is not impeded at all.

Those 'fishnet' style bags won't work, unless your carbon is super chunky. I suppose you could line one with a pre-filter, tho....

If you go on eBay and search this phrase you should be able to find the seller I purchased these bags from, super cheap.

2 x fine mesh laundry bag（40x50cm) + 2 x framed lingerie bra underwear mesh bag

This seller also includes bra protectors that fit nicely into my passive intakes, I have sandwiched some loose carbon between some pieces of carbon furnace filters to cut down on the unavoidable carbon dust.
