Highly accurate Z-box air classifier

Sorting materials according to density has just become more precise and flexible than ever. Developed by leading recovery specialist AirSort® not only separates fluff from ASR. It also allows precise separating of wood, foam and film from heavy particles such as metals and hard plastics. The clue is the combination of the zigzag sifter channel with a state-of-the-arte simulation model to adapt the system to your specific needs. This allows a precise and fully automatic adaptation of the air flow.

Ready for operation
