As a beta module, some fine tuning can be needed

The Open/Close loop option allows to automate recirculation or not in filter output.

Open loop: filtered air escapes to the outside to avoid overheating of the chamber (PLA/PETG)

Close loop: filtered air is recirculated internally to keep room temperature, lower power consumption, and noise (ABS/ASA/PA/PC)

Refilable cartridge V2.5, effective lifespan between 12 and 24 months depending the usage

Question of the price;

Some will see this rather high price: There are two types of filters:

Filters with carbon cartridge, and without. The cartridge models split the HEPA function and the activated carbon system.

The others have only a fine impregnated fabric. The carbon filtration mechanism depends on the absorption surface, therefore on the granulosity and the volume. A professional filter of equivalent capacity costs between 30-40% more, not counting refills between 200 and 600% more!

The high capacity of the CF80 allows effective filtration over a long period of time, and with a refill cost of less than 20 Euros
