Carbon Pellet Enclosure Air filter

thingiverse

Enclosure Fan-Vent for 92mm computer fan designed specifically for use with activated carbon pellets. This custom-designed fan is intended solely for personal use, and I make no claims regarding its effectiveness. The container holds approximately 11 ounces of activated carbon pellets, which can be easily cut to fit filter pads. The package includes an optional 14mm depth grommet for fitting through Johns Manville foil-faced insulation. If you choose to use the grommet, it's recommended that you apply sealant to prevent air leaks. To assemble the fan-vent, you'll need eight screws and four machine screws and nuts. I used eight #8 x 3/4 inch screws and four #6-32 x 1 inch machine screws and nuts. Unfortunately, I'm not aware of the best metric equivalents for these components. The files included are a straight and angled vent piece, but you can only use one. Originally, I planned to use the angled vent, but due to limited filament availability, I opted to create and print the straight version instead.
