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.

Key Features

Active Exhaust & Purification

• Upgrades the P2S with active exhaust capabilities.

• Automatically expels residual gases after printing when "Purify Air at Print End" is enabled for materials like ABS and PA.

Smart Mode Switching

• The printer automatically switches operating modes based on the filament type.

• Manual override available via the printer screen, Bambu Studio, or Bambu Handy.

Vibration Isolation

• Floating damping structure effectively isolates fan vibrations, ensuring print quality remains unaffected.

Quick-Release Design

• Allows for easy and rapid installation or removal based on user scenario needs.

Expandable Filtration

• Supports expandable air filter cartridges (sold separately) for enhanced air purification.
