No because it's a HEPA filter, you'll need an activated charcoal filter, those 6 fans would be enough for a 2x2 but keep the filter thickness in mind, as PC Fans do not create large amounts of pressure
@protatorАй бұрын
A quick suggestion: Make one with 7x P12 or P12max instead of the 6x P14. The P14 is a decent allround pc case fan and not horrible as a radiator fan, especially for the money, but it doesn't have the static pressure you want for a filter application. They look good on paper, but that cfm number goes down the drain as soon as the airflow is impeded, to the point where they're easily overtaken by their smaller brothers. Even at the same noise levels. In a pc a 480x120 radiator with 4x P12 will outperform a 420x140 with 3x P14 by a good amount, even though the latter has more surface area. And a particle filter is even more restrictive than the fin array of a pc aio cooler.
@maverickjoe03Ай бұрын
Asking cause I don't know: Can you explain the static pressure in this circumstance? Specs on Arctic's website indicate that P14 has a static pressure of 2.40mm H2O and P12 has the static pressure of 2.20mm H2O. I looked at it this way when specing out a similar build. I wouldn't do the P12 max because it takes 2x the amount of power an equiv P14 will consume. However, I see that the static pressure of the P12 max is 2x that of the P14.
@RobertFantinattoАй бұрын
We make a 5-fan unit using the P12s, we avoid the P12max as we're trying to make a quiet machine that relies on multiple passes through a large filter area to give you the same performance as a loud commercial HEPA at full speed. We do use the P8 Max fan in our MINI version for travel.

PC fans are not good at creating high pressure. I reckon it would be way better to have a slightly bigger box that uses 4" filters instead of 1", to get a much bigger surface area and significantly higher airflow. You could also run the fans quieter and still get better performance. Also for literally just a couple bucks you could have a PWM controller to control the speed of these fans. Some people like it quieter, others prefer more airflow. But the choice of fans is great. The Arctic P12 are the best budget fan there is. Though at this point the P12 MAX is probably a better choice as it's only a little more expensive at 37 bucks for a 5-pack and is a little quieter while offering similar or even better performance and higher max fan speed.
@RobertFantinattoАй бұрын
We use the P8 Max for our MINI, very powerful but very loud. The Arctic P14 has good static pressure and runs very quietly.

I'm confused. A MERV 13 filter can catch 75% of air particles that are 0.3-1.0 micron in size. Increasing the air particle size range to 3-10 microns, a MERV 13 filter will catch 90%. Airborne viruses like COVID19 are approximately 0.1 micron. That said, wouldn't an airborne virus just pass right through that filter?
@RobertFantinattoАй бұрын
The virus is 0.1 micron but they travel through the air by attaching to a respiratory droplet that is 1 micron or larger. The idea is to use a large filter surface and multiple passes to achieve better performance than HEPA despite the greater single pass performance. Here is a good explanation: itsairborne.com/clean-air-delivery-rate-is-all-that-matters-5a5a064c211e
@Violet-uiАй бұрын
0.2 to 0.3 micrometer particles are the hardest to catch. Bigger OR SMALLER is easier to catch. Smaller particles are so light, they get punched around by air molecules, which makes them move through air in a zigzag pattern. The smaller they are, the more likely they are to hit the filter and stick to it. MERV 13 should filter about 50% of 0.1 ym particles. MERV 12 about 30. MERV 11 about 20. MERV 8 about 10%.
@RobertFantinattoАй бұрын
@@Violet-ui Everything I've read about virus particles in airborne form is they travel on aerosolized liquid particles expelled from person to person, these particles are 1 micron. Also, the performance of the filters in one pass is made up by the large filter surface of two 20 x 20 inch filters, cfm of the fans plus the multiple passes of the same air through the system.

I am working on a 6 fan machine that uses the 140mm fans, primarily as a silent solution for classrooms. The 2 fans are placed on the bottom as that configuration gives the best performance (CADR) when using a 5 fans set up likely due to less turbulence.

I 'd like to know what the fan connectors ,power switch with wiring and power supply are and where to get them ,also is there a way to make these variable speed ?
Where can I find those fan grills/push pin fasteners?
The kit doesn’t come with it? 🤔
Well done 👍 Is the fan metal? I am new to KZread shorts and I'm wondering is there information on for this corsi fan?
Hi, you can check them out here: aidankepo.wixsite.com/northboxsystems
Hi. Thank you so much for your reply. I appreciate your help. So I have a few more questions if you could. Do you sell these? What would the total cost be for this unit? could I get my own style of filter? would it work, If it wasn't the one seen on this video?meaning would it stress the motor if it wasn't the same type?@@RobertFantinatto
Any chance you will have a 140mm version?> For wiring any chance you will go down the USB route so we can use a power pack or usb charger instead of barrel type plug? And out of curiosity why are the two fans at the bottom instead of much higher. Wouldnt the bottom push out more dust on the floor? Thank you.
I am working on a 6 fan machine that uses the 140mm fans, primarily as a silent solution for classrooms. The 2 fans are placed on the bottom as that configuration gives the best performance (CADR) when using a 5 fans set up likely due to less turbulence. Extensive testing by Rob Wissmann of different fan configurations was used as the basis for the design: x.com/robwiss/status/1584723252340891648?s=20
@@RobertFantinatto That is great to hear! I am guessing with 6 fan setup you are going with a different filter size 16x 25? or are you going with 20x 20
Whoops! Yes that setup looks awesome on the 20x20x1
Where are these available?
Hi, free delivery in Toronto, but we will ship anywhere to Canada and US. send me an email at [email protected] or visit: aidankepo.wixsite.com/northboxsystems
@@RobertFantinattodo fans with lights use more energy & are they an option?🤔 The colored lights would look cool on the black acrylic case‼️❤️😅
@@capcom4eva You can get our bare kits that do not include fans, lighted fans will require additional electronics to generate the 5 volts from the 12 volts to power the LEDs. The LEDs themselves do not use much power at all.
9ft tall neverending rack, you mean like neverending horizontally or in depth?
I finally got around to building mine today. Thanks so much for making these available to Canadians!
I used 2500 filters. Will that affect the output?
@@ExtraAdventure Sorry I just saw this, I frequently use MPR2200 and the 2500 are rated MERV14, I don't believe they will affect the airflow.
This looks amazing! Do you ship to the U.S.?
Great Simon 🌱

A wonderful video ! Thank you for posting this.
Emerson, genius
Just finished mine... !! kzread.info/dash/bejne/gop8urKfptDOk5c.html
I have it on CD rom but can't watch it on my Macbook. Can I see it streaming somewhere?
If you have a library card you can sign in to Kanopy and view it there, it's the "home video" cut, not the 3+ hour hardcore edition.
@@RobertFantinatto Thank you! I really appreciate the fact you respond so quick! 🙂
GOOD!!! kzread.info/dash/bejne/Z2ZsptaBd6zIl9o.html A documentary of AMAZING collection of vintages analogs synths & drums machine in FRANCE
Less a documentary, and more a sequence of talking heads making random comments.
This is just the trailer…
I like that this is all happening again, but with visual art, with things like Artbreeder, deepart, or VQGAN+CLIP.
Someone should put this song over a fat lady taking a dump on the streets of LA
In short, it's fun to press a button that makes a cool noise, and play with it all day long.
So were not gonna talk about the guy in all white?
Go ahead...
Really beautiful Robert !!!!!!!!
Let’s geek out

Just within the few seconds of this video, I got a geeky boner seeing all this knobs, wires and even tactile controllers, endless possibilities beyond the imaginable ! ♥
super
Amazing every of this artists evolve and grow with their instrument. Every of them has their unique specific set of sound waves which they crafted by many years of experimentation. Beautiful.
