🔍 Product Overview

The Bambu Lab External Exhaust Fan Kit is an official upgrade for the P2S printer, designed for users with strict ventilation requirements. While the P2S defaults to an internal air recirculation system with an activated carbon filter, this kit adds active exhaust functionality.

It allows for the directional expulsion of fumes, making it safer and more efficient when printing engineering materials. The kit features a floating damping structure to isolate vibrations and a quick-release design for easy installation or removal.
