P2S External Exhaust Fan + HEPA 13 / Activated Carbon Air Filter Combo Transform your p2s bambu lab into a truly healthy printing workstation. The original external exhaust fan kit adds active exhaust to your printer, while our HEPA 13 + activated carbon air filter captures ultrafine particles and VOCs before they leave the machine. This is the complete 3d printer ventilation kit that Bambu Lab P2S owners have been waiting for. Why you need active exhaust + filtration. Your P2S comes with a built‑in recirculating filter – it only uses activated carbon and simply moves air around inside the chamber. Ultrafine particles (UFPs) are never trapped, and odors/VOCs stay in your room. Our p2s external exhaust fan actively pulls contaminated air out, and the included p2s exhaust fan filter (HEPA 13 + honeycomb activated carbon) cleans that air before it exits your printer or goes outdoors. Capture 99.97% of PM2.5 and nano particles while adsorbing formaldehyde, fumes, and harsh smells from ABS, ASA, nylon. Smart, automatic performance. The p2s exhaust fan integrates seamlessly with your printer's firmware. When printing PLA/PETG/TPU/PVA, the fan automatically runs (variable speed) for cooling and fume extraction. For ABS/ASA/PA/PC, the fan defaults OFF to prevent warping, then activates a full post‑print purge – and our filter ensures toxic residues are filtered, not just blown outside. All controlled via Bambu Studio or the printer's touchscreen. Installation – straightforward, with options. Two installation plans are provided (refer to Bambu Lab Wiki). You can reuse your original rear panel – the exhaust port is cleverly positioned on the right side of the purge chute. Or you can replace it with a dedicated rear panel (not included) for optimised airflow. In both cases, you will need to 3D print the fan housing (STL downloadable from Bambu Lab Wiki) using PETG, ABS or PC. The kit includes the fan, circuit board, 6‑pin cable, screws, and our premium air filter. Note: If you own the P2S without AMS, you must purchase an additional buffer accessory to use this exhaust fan kit.
