3D model description

After I saw the video from Zortrax about their HEPA Cover Filtering Device (see link below) I think “for me” a HEPA and active carbon filter is plenty sufficient for keeping the air clean in my 3d printing enclosure. Certainly better than nothing. But I’ve designed it with a radial blower and in such a way that the air is recirculated inside the enclosure to avoid a draft.

This is the second version of my design. The first used a very good ULPA U15 filter but it was only available from 1 seller in ebay germany so not very useful for everyone. Therefore I searched for alternatives and I found these much cheaper Zortrax HEPA cover filter set. They’re available everywhere. Im sure they are also way cheaper on if you know what to search for.

I had to redesign the housing completely because the new filters where too big and didn’t fit into the old housing. I’ve tried to integrate snap-fit connections in the filter housing. They kind of work but are not the best (this is my first try on snap-joints, feel free to do a remix). You need to use super glue on the snap-joints if you want the filter housing cover to be firm.

Bill of materials:

4x Neodym magnets N52 ø10mm x 3mm
12x 2,9mm x 9,5mm ISO 14586 screws
2x M4 x 35mm screws
2x M4 washers
2x M4 nyloc nuts
1x Titan Blower TFD-B9733M12C
1x HEPA & Carbon Filter set from Zortrax (3sets)
1x Self adhesive foam rubber (thickness 2mm)
1x PWM low voltage motor speed controller with switch 12V/2A
1x DC power jack socket with ø8mm thread

The 4x Neodym magnets are integrated into the “blower housing magnetic cover”. Just add a pause or filament change in the slicer at “layer 20” or “height 4mm”.

Fix the funnel with two stripes of self adhesive foarm rubber to the titan blower.

The fan blower has plenty of suction and does not need to be on full speed.

If you don’t have the metal server cabinet as enclosure use the “blower_housing_screw_cover” to fix the AirManagerV2 to your enclosure.

No supports needed but I used a brim on all parts to avoid any possible warping. I used Prusa PETG for all parts but I think you can use PLA too.

Here is a short test video of the AirManagerV2 with an incense candle:
