Not sure if this has been mentioned yet. If you want to turn off the chamber exhaust fan or run it at a slower speed for certain parts or filaments you can follow the steps in my pictures.
I do believe this is no longer an available setting. So is there any way to adjust the exhaust fan speed within Bambu Studio?
Welcome to the forum.
This setting is still in Bambu Studio. Just follow the steps as discribed above.
Hi Jon, can you tell us your Studio version and how you get this setting to show up?
There seem to be reports to the contrary, e.g.: H2D: Exhaust Fan / Air Filtration Control Removed in Latest Bambu Studio Release · Issue #9542 · bambulab/BambuStudio · GitHub / Air filtration enhancement no longer present under printer settings
Looking at the current Studio code, on the printer side the “Air filtration enhancement” setting (support_air_filtration) seems exclusive with “Use cooling filter” (cooling_filter_enabled) based on the value of support_cooling_filter of a printer. If support_cooling_filter is false (“0”) then “Air filtration” option shows up, otherwise “Use cooling filter”
On the filament settings side, “Activate air filtration” checkbox (setting name activate_air_filtration) only shows up when support_air_filtration is true (“1” or “true”).
It’s possible that any printer/filament/project profiles saved while the feature was available (in v2.4) would still show the exhaust fan options. Or that editing the files manually would make that option show up again. I think some machine filament start g-code analysis is needed to check whether either option will have any actual effect (and there might be different versions of this startup code as well).

EDIT: The relevant g-code that uses support_air_filtration & activate_air_filtration properties is in filament settings, not machine/printer (though the default filament presets can vary by printer, of course). cooling_filter_enabled is used in machine start g-code.
When I checked earlier it was a fresh install of 2.5.0.66. I just followed the steps. Turn on “Activate air enhancement” in the printer settings and then “Edit” the filament settings. I didn’t realize that I had the X1C selected.
I tried it with the H2D selected and, yup as @They_Call_Me_User1 said, the setting isn’t available.
Thanks for pushing further into this.
i am having some issues with my H2D when i am printing PETG the chamber temp is overheating to 44C getting a over heat error. the fan speed is auto so i can’t change anything, there is no option to change it but on my h2c and x1c there is an option to adjust the fan speed manually.
