3D printer toolheads often have large blower fans with big fan ducts ending in small holes and I wonder how necessary that is.
These large part cooling setups are most of the size of the toolhead and significantly reduce print area. Blower fans also do not produce much pressure so those fan ducts greatly reduce their effectiveness.
Does it make sense to, instead of using a blower fan, use a small compressor like for an aquarium and have the airflow delivered Bowden style to a small nozzle? The airflow would be substantially higher than from a fan. Noise isn’t really an issue for a tiny compressor.
Has anyone tried this? I might eventually but don’t have the time to set it up now.

Nice, that is indeed what I meant. Recently I’ve designed a new toolhead for a 3D printer but have just used blower fans and fan ducts like any other toolhead but while designing I wondered if more weight/volume could be removed without losing functionality.
