Ventus 4 Density Separator

Four-Fractions, One Machine.

Don’t toss your valuable organics - separate them! Throwing out your contaminated overs costs you in lost revenue and removal expenses, but the EcoSift Ventus 4 Density Separator lets you easily decontaminate your overs inline with an existing screening system or recover valuable organics from a legacy overs pile. It’s the decontamination solution you’ve been searching for.

Using innovative air drum technology, the Ventus 4 density separator removes heavy aggregates and other contaminants at the start of the separation process. Then a magnet separates ferrous from non-ferrous metals and the lighter fraction contaminants move to the triple suction fans which removes plastics and light fractions and discharges the contaminants out of a vent.

You’re left with clean, contamination-free, sellable material.
