Description
The model is a refillable air filter for the original External Exhaust Fan Kit designed for the Bambu Lab P2S and X2D.
It can be used in combination with my additional HEPA filter or standalone.
Any commercially available activated carbon pellets can be used. The only requirement is that it must be acid‑free.
With the filter, VOCs generated during printing of PLA or PETG are captured. Thanks to the active exhaust fan, these gases are no longer blown uncontrolled through any openings in the printer; instead they are routed through the filter in a controlled manner.
Optionally, a filter fleece up to 3 mm thick can be used to keep fine activated‑carbon particles from escaping the filter. Because the exhaust air is blown out of the printer, this isn’t strictly necessary but is recommended to avoid environmental contamination. The less finer the particles in your activated carbon are, the less critical the filter felt becomes.
Print and Assembly Instructions:
It is recommended to use PETG or ABS/ASA for this filter.
