MOBILE AIR SEPARATION TECHNOLOGY

Air Classifiers from SPALECK

How a Wind Sifter Works

What is a wind sifter?

The separation of light and heavy materials using a stream of air is a proven recycling process. It is used to separate and process a wide variety of waste streams. The principle is based on a method that has long been used in grain harvesting. Air classification itself refers to the process of separating fine particles and is widely used in Sorting plants as well as in the recycling sector.

Technology that convinces

Principle of Airflow Mixing

Using a powerful airflow, the Wind-shifters separate light materials from heavy ones based on their density and particle size.

Compact ExtractVac Series

Models such as the AV9 1600E and the AV4 1200E feature a compact design, electric or hydraulic drives, and easy integration.

Separating Drum

The integrated drum ensures precise separation: Light fractions are blown out, while heavier ones remain behind.

High-Performance Diesel Engines

The air separators offer powerful diesel engines, an adjustable airflow of up to 112 m³/min, and maximum mobility.
