This model was created to hold a 120mm axial fan and an ALVEO3D HEPA filter, which you can buy from the Prusa Eshop or the official ALVEO3D website.
Important Note: A standard PC fan will not be sufficient!
Only use this model if you have an industrial fan with high static pressure, such as a high-performance Noctua fan. I tested a Be Quiet fan capable of 3000 RPM, but even that I found too weak to overcome the filter's resistance.
While you can use the ALVEO3D axial fan, which is specifically designed for this type of workload, I strongly recommend using a radial fan (turbo) fan if you don't already have a high-pressure axial fan in the shed.
Radial fans generally have lower CFM compared to axial fans, but they excel at generating much higher static pressure, making them more suitable for use with HEPA filters.
For a 120mm turbo fan holder you can use Pusa's design.
