URSTAG air separator — the air stream splits the light fraction from the heavy one
Back to catalog

Air Separator

It separates by density rather than size: the air stream carries film, paper and textiles away, while glass, metal and stone drop straight down.

Sustainability impact

Equipment engineered for long-lasting operation and built from recyclable materials, in line with the principles of the circular economy.

Key features

Separation by density

an air separator solves what no screen can: it splits two objects of the same size but different weight.

It produces the combustible fraction

the light fraction is exactly the high calorific material from which RDF alternative fuel is made.

It protects the heavy equipment

by pulling stone, glass and metal out of the light flow, the shredders and presses downstream no longer take the objects that damage them.

Product description

Every other screening machine separates by size. An air separator does something different, and that is exactly why it is indispensable: it separates by density. Two objects of the same size, a plastic bag and a piece of brick, leave on different streams, which no screen in the world can…

Municipal waste

Municipal waste sorting plants, from the bag to recoverable material

Household waste arrives mixed and bagged. A sorting plant opens it, screens it into size fractions, separates the light material from the heavy one and extracts metals, plastic, paper and glass. We configure complete lines and also supply the individual machines, from the bag opener and trommel screen through to the magnetic and eddy current separators, the optical sorters and the balers.
