An Air Density Separator, also known as a Wind Sifter Separator. It is an advanced mechanical system designed to sort waste materials based on their density, shape, and weight using a stream of controlled airflow.

At its core, the air separator machine uses aerodynamic forces to separate light materials (like paper, plastic film, and textiles) from heavier particles (such as stones, glass, or metals). When mixed material is introduced into the separation chamber, the airflow lifts and transports light fractions and is propelled forward while heavier components fall downward due to gravity and inertia.

This process, referred to as density separation, is essential in waste treatment facilities, particularly in RDF production, Waste sorting, and construction & industrial waste recycling.
