FFU - FAN FILTER UNIT 3D ILLUSTRATION
A fan filter unit (FFU) is a device that cleans the air in a cleanroom, laboratory, or other environment that needs to be free of dust and germs.
It has a fan, a pre-filter, and a main filter that can trap very small particles.
This is a simple illustrative model. It includes the FFU unit, pre-filter and HEPA filter separately.
This is just a visual model, not a technical one. It is modeled after a real working machine.
