NexGen CleanAir Desktop Edition

I created this to help keep my office air toxin free as I run several printers in there with me and I think there would be a few others that also do this.

I already run my CleanAir filters inside the printers and they do take care of most VOC's but I can sometimes still smell ABS/ASA so I thought I would make a quiet constant filter system to clean things up a little more.

This is a simple device that you can leave running and every few months replace the Activated carbon pellets.

My Initial readings in my office were not terrible, but it could be better, after 48hrs of having 2 of these running, with 2 printers pushing out ABS the entire time, they managed to scrub the air to what I can say, is very acceptable, pictures attaced.

Parts required for this project:

• 25mm x 120mm Fan, recommend due to low cost and noise is the Artic P12, but you can use a Noctua or any other fan that is designed for high static pressure.
• 4 x M3 x 50mm Bolts, these dont need thread all the way so any type will do
• 1 x M3 x 8mm or longer
• 5 x M3 Heat Inserts
• 1 x XT60 Panel Mount, I used these as I had them kicking about already.
• 1 x USB-C PD Trigger Plug (Get the one to match your fan voltage, I use the 12v ones)
• 1 x USB-C Phone Charger/Wall Wart (Any type should do)
• 1 Bag of your faverite Activated Carbon Pellets
• Some 2 Core cable, anything will do, power requirements for these fans are next to nothing, maybe some old speaker cable, or you can cut up an old USB cable, what ever you have laying around should be okay.

Printed parts required per cleaner:

• 1 x Main Body
• 3 x Static Pressure Booster
• 1 x Cage
• 1 x Cover

Intake is the top of the unit and it will vent out of all 4 sides, its just a slow radiant flow of air, nothing with any force, its just designed to work slowly and quietly in the background, set anf forget, annd if your keen, you can make a bunch of them and put them all around the place.

1. Put the 4 heat inserts into the Main Body.
2. Then insert the fan, intak faces the top of the top/intake of the main body
3. Then insert the 3 static pressure boosters, the “IN” faces the fan for all 3
4. Then install the heat insert into the bottom of the cage
5. Then install the cage
6. Clamp all of thes parts using the 4 x M3 x 50mm Bolts
7. Install your XT60 Panel mount and solder the power wires from the fan.
8. Fill the camber to the top with carbon pellets
9. Install the bottom cover
10. Make your cable using the XT60 connector and the USB-C Trigger connector and what ever cable you went with.
