Pneumatic Eductor for moving dry materials
thingiverse
This is a pneumatic eductor that I printed to shoot food pellets to my fish, and to move dry concrete mix underneath a culvert. Fox Venturi Products has a good overview of how they work and their uses. Not an endorsement, just good information https://www.foxvalve.com/solids-conveying-eductor-systems/introduction/ Link to a video of the eductors in action. https://www.youtube.com/watch?v=0xNC7P4DmRc&feature=youtu.be
