Bambu Lab Part Cooling Fan for H2S – FAF020

The original part cooling fan for Bambu Lab H2S and H2S Laser 3D printers (compatible with the H2 Series, H2S variant) is a spare part intended as a direct replacement for the original fan located at the bottom of the toolhead. Together with the original air duct, it provides fast and targeted cooling of the extruded filament directly at the print point.

Thanks to precise regulation in a closed loop control system, the fan maintains an optimal airflow, which leads to better surface quality, sharper edges, and reliable printing of bridges and overhangs, even at the high speeds for which the H2S is designed.
