Enhance your printing environment with the External Exhaust Fan Kit for the Bambu Lab P2S. Designed to upgrade the printer’s internal air circulation system, this kit enables active external exhaust—efficiently removing fumes, odours, and airborne particles from the print chamber. Ideal for users working with engineering-grade filaments, it delivers improved air quality, smarter airflow control, and seamless integration with your printer.

Key Features

• Active External Ventilation
  Converts the P2S from internal air recirculation to powerful external exhaust, directing fumes out of the printer for a cleaner workspace.
• Smart Automatic Operation
  The printer detects the kit and automatically adjusts airflow modes based on filament type, ensuring optimal ventilation at all times.
• Post-Print Air Purification
  Automatically activates exhaust after printing to remove residual gases before opening the chamber—ideal for ABS, ASA, and PA materials.
• Seamless System Integration
  Fully controllable via the printer touchscreen, Bambu Studio software, or mobile app for complete airflow management.
• Enhanced Safety & Comfort
  Helps reduce exposure to VOCs, fumes, and odours, making it suitable for home, office, or workshop environments.
• Expandable Filtration Support
  Compatible with optional filter cartridges for additional air purification if required.

Variant Options

1. External Exhaust Fan Kit (Standard)

Best for users with newer P2S units that already include the updated rear panel.

Includes:

• External exhaust fan
• Control circuit board (enables exhaust functionality)
• 6-pin connection cable
• Mounting screws and hardware

Key Benefit:
Adds automated exhaust capability without requiring additional hardware changes.

2. External Exhaust Fan Kit + Rear Panel

• Everything in the standard kit
• Updated rear panel for improved airflow efficiency

Key Benefit:
Optimised airflow performance and easier installation, ensuring maximum exhaust efficiency.

How It Works

The standard P2S uses an internal activated carbon filter to recirculate air within the chamber. This upgrade introduces directional airflow, allowing fumes to be actively expelled outside or into a dedicated filtration system. Once installed, the printer unlocks enhanced airflow modes and automated exhaust functionality.

Ideal Uses

• Printing with ABS, ASA, Nylon (PA), and other high-emission filaments
• Indoor or enclosed printing environments
• Users requiring improved air quality and odour control
• Professional, workshop, or office setups
