Air Separator a system to separate wastes according to gravity by blowing air onto the waste stream. The separator is usually installed right before the automatic sorting machines to sort out the film, paper and dust for high efficiency and purity of automatic sorting machines.


  • The air separator, is composed of a re-circulation fan, a separation section and an input section.

  • The input material to the air separator, conveyed by a belt conveyor, ends up in a extractor hood.

  • Here, thanks to the controlled air flow generated by the fan, the light fraction (plastic bags, plastic film, light packaging) is aspirated upwards and continues its path in a series of piping, while the heavy fraction (plastic bottles, plastic containers, heavy objects) is discharged on a second conveyor.

  • The light fraction then reaches the rotary valve, in which, thanks to the movement of the rotor and the consequent reduction of the air speed, the lightweight material is unloaded on another conveyor.

  • The air then continues its path towards the fan, after which there is a dust suppression filter, thus closing the air re-circulation.
