The Bambu Lab Chamber Temperature Regulator Fan is the OEM replacement fan responsible for regulating and circulating air within the print chamber of Bambu Lab enclosed printers. By actively managing airflow inside the enclosure, this fan helps maintain a stable, consistent chamber temperature that reduces thermal gradients across the build volume, improving layer adhesion and reducing warping for temperature-sensitive filaments.

A failed or under-performing chamber fan results in uneven temperatures within the enclosure, which can cause warping, poor layer bonding, or inconsistent surface finish. This OEM replacement restores proper chamber airflow regulation and works in concert with the printer's thermal management system for reliable enclosed printing performance.

Key features

• OEM chamber temperature regulator fan, actively managing airflow and temperature distribution in the print enclosure.
• Reduces thermal gradients across the build volume for consistent layer adhesion from base to top.
• Improves warp resistance for temperature-sensitive filaments such as ABS and ASA in the enclosed chamber.
• Restores proper chamber airflow when the original fan has failed or produces insufficient airflow.
• Also available: Control Board Fan (article 210000005888) for the mainboard electronics cooling system.

Compatible with: Bambu Lab P1S, X1C
