## Summary description

Air duct designed for the cooling fan of BambuLab hotends in the H2D and H2C series. This component directs airflow from the fan to the hotend area to improve filament cooling and print quality. Intended as a replacement or upgrade part for BambuLab printers using H2D/H2C hotends; useful for maintaining consistent cooling, reducing stringing and improving small-feature detail.

## Long description

Cooling fan air duct for BambuLab hotend H2D/H2C compatible with BambuLab printers directs airflow from the cooling fan precisely onto the hotend and printed part. Designed for use with H2D and H2C hotends, this air duct replaces or upgrades the original channel to maintain steady filament cooling, reduce stringing and enhance detail on small features. The component is intended for reliable, repeatable cooling performance in FFF/FDM desktop printers that use the BambuLab hotend family.
Advantages
The air duct provides a focused airflow path to the hotend, improving layer cooling without introducing turbulent air patterns that can affect print adhesion. Its design supports consistent part cooling across a range of print speeds and materials, which helps reduce common print defects such as stringing and poor bridging. As a direct-fit replacement or compatible upgrade for H2D and H2C hotends, it simplifies maintenance and can restore or improve cooling performance when the original duct is worn or damaged.
Suitable for
 Replacement of a damaged or worn air duct on BambuLab printers with H2D or H2C hotends
 Upgrading cooling performance to improve fine-detail printing and bridging
 Reducing stringing and improving surface finish when printing PLA, PETG and similar filaments
 Use in routine maintenance to restore original airflow direction and consistency
Key specifications
 Compatibility: BambuLab hotend H2D and H2C series (compatible with corresponding printer models)
 Function: Directs and focuses fan airflow toward hotend and printed area
 Material: Durable thermoplastic suitable for printer environments (heat-resistant)
 Mounting: Designed for direct-fit installation with the stock fan and hotend assembly on compatible BambuLab systems
 Performance: Supports consistent convective cooling to reduce stringing and improve small-feature detail
How to use
Power down the printer and allow the hotend to cool before beginning any replacement. Remove the existing air duct by loosening the relevant screws or clips, taking care not to disturb the fan wiring or hotend nozzle. Fit the new air duct in the same orientation as the original, ensuring secure seating against the fan housing and hotend shroud. Refasten screws or clips to the manufacturer’s recommended torque, verify that the fan spins freely without contact, and perform a short test print to confirm cooling performance and proper airflow direction.
Usage recommendations
Inspect the air duct periodically for cracks, deformation or buildup of filament residue. Clean with a soft brush or isopropyl alcohol if necessary, and replace the duct if damaged. When changing printing materials or significantly altering print speed, verify cooling settings in slicer software to complement the duct’s airflow characteristics.
