This filter system uses 4 120mm PC fans, 2 LV-H128 HEPA filters, and a temperature controller to help regulate temperature and filter intake and exhaust from printer enclosure.
This could also be configured to a single exhaust unit using half of the above hardware.
Must use a high static pressure fan. I used Arctic PC12 Max and was happy with the airflow.
Print list to make both intake and exhaust:
2 x Filter Box
4 x Fan Box
2 x Fan Face
2 x Flow Director
2x Face Plate
Printed in Overture Orange PETG with .8mm nozzle. (Flow director printed in black) Supports used where needed.
