Cylindrical Impeller 3D Models: STL Fans and Pumps
This collection gathers cylindrical impeller models used in pumps, fans, blowers and small turbine assemblies, from simple rotors to multi-part housings. Most files are meant for 3D printing, so the blade geometry and the hub bore matter as much as the outer shape. It helps if you already know the shaft diameter and the space the impeller has to fit into. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

Comment cette collection est composée
Polyzon compose cette collection à partir des résultats de recherche des plateformes connectées. Les doublons et les modèles sans aperçu sont retirés, les correspondances faibles sont placées à la fin, et le reste suit l’ordre de la recherche. Les modèles appartiennent à leurs auteurs : consultez les conditions sur la page de chaque modèle.

«Cylindrical Impeller 3D Models: STL Fans and Pumps»
The models fall into a few groups. Pump and water-jet impellers usually have a closed or semi-open rotor with a central bore, while radial fan wheels for motors and handheld blowers tend to have wider, shallower blades. Blower and vacuum parts often come as a set with a housing or turbine ring, and engine or turbo models are frequently multi-part assemblies rather than a single printed piece. Propeller-style files are often parametric, so blade count, pitch and diameter can be adjusted before export.
When choosing a file, check the dimensions the author lists: outer diameter, hub bore, shaft type and overall height. Look at how many separate parts are involved and whether the blades need support material, since thin curved blades are where a print is most likely to fail. The material and layer settings on the model page give a useful starting point, and photos of real prints show how the blades actually come out.
To narrow the search, try synonyms such as rotor, fan wheel, centrifugal fan, blower wheel or turbine, and add the intended use — pump, water jet, vacuum, motor cooling. Adding a diameter or shaft size to the query helps when you are matching an existing part. Related topics like ducted fan housings, propeller blades and parametric impeller generators can also lead to files that fit the same project.
