P2S Ventilation System – Premium 5-Stage Air Filtration for Bambu Lab P2S

FNATR’s turbo fan is intended to help maintain negative pressure. The official fan kit primarily pushes air out through an exhaust path, but it does not necessarily create stable negative pressure across the whole enclosure. On P2S, enclosure sealing is not as strong as some higher-end models, so when printing ABS/ASA and other higher-emission materials, fumes can still escape through small gaps instead of being consistently pulled into the exhaust path (results depend on sealing and room airflow).A single filter layer is often not enough. Even if you add a basic filter, many setups rely on a single layer of media, which can be less effective for a mix of particles and odor/VOC reduction. FNATR’s stacked design adds multiple filtration stages so air is routed through each layer sequentially (results depend on filter condition and replacement).

FNATR’s P2S ventilation system is an external exhaust and filtration solution engineered for Bambu Lab P2S when direct outdoor venting is not available. It uses a turbo fan to create negative pressure and route enclosure air through a 5‑stage filtration stack (pre‑filter, HEPA, activated carbon, photocatalyst, and negative ion media) to help reduce odors, fumes, and airborne byproducts from materials like ABS, ASA, PETG, and other engineering filaments. using an AMS riser (more heat release, but potentially less sealing) or pairing with the Bambu Exhaust Fan Kit + Filter (tighter sealing for more controlled extraction). Rated airflow is 11.8 m³/h and rated noise is < 30 dB (claimed). Installation is designed to be fast and non‑destructive, and it is compatible with the original P2S glass lid. Actual performance depends on filament, print temperature, sealing quality, duct routing, room ventilation, and filter condition; no system can guarantee complete removal in every environment.

Instead of ducting the printer vent into a typical household air purifier (which is designed for room recirculation and is usually not a one-way check valve), FNATR is designed as a directional, ducted exhaust path: air is pulled from the P2S enclosure and pushed through the filter stack in one direction, which can reduce “blow-back / re-intake” behavior and lower the chance of exhaust air mixing back into the room. A more one-way flow path can also reduce backflow risk around the vent connection and be more consistent than improvised adapters, though results still depend on sealing and installation quality.
