Westeria - Wind Sifter

Westeria®’s entire windsifter range(AirStar®, AirTrack1 and AirTrack2, AirBasic®) combines efficiency and light weight despite of its robust design. The materials are separated by a process that is divided into three basic components within the windsifter - the acceleration belt, the air nozzle and the separator drum. By means of the constant and single-layer distribution of the input material, which is homogeneously distributed over the whole belt width of the windsifter and fed onto the feed conveyor, the systems obtain a good separation result.


Available models

The windsifters from Westeria® are designed to be rugged, powerful and energy-efficient.
A powerful method to separate heavy and light materials is what sets the patented Westeria® windsifter technology apart. 

In the windsifter, the materials are separated by a process that is divided into three main components: the acceleration belt, the air jet and the windsifter separation drum.

With its uniform and single-layer distribution of the input material, which is distributed homogeneously across the entire width of the windsifter and fed to the feeding belt, the windsifter achieves excellent separating results. 

The material in the windsifter is accelerated to an adapted speed here and transported to the ejection edge. The materials falling from above get into an upcurrent that is generated through an adjustable air jet that is attached in the windsifter underneath the feeding belt. 

The air stream meets the upper area of the rotation drum in the windsifter and is fed through it into the expansion chamber with the laminar flow. 

The material in the windsifter meets the air flow and is separated into light and heavy materials. 

The light materials are transported with an air flow with high speed into the expansion chamber, where the air speed is reduced so much that the light materials reach a container or a discharge belt. The heavy materials fall down from the rotation drum in the windsifter into a container or onto a discharge belt. 

The air volume brought into the expansion chamber is removed again in the upper section of the windsifter and, depending on the individual application, is once more drawn in by the blower or routed into a filter system. To retain high-grade recycling raw materials, Westeria® has designed a special windsifter to unerringly sort the input material into three fractions with a high degree of selectivity.

Operators of composting plants know the problem all too well: Organic household waste is often contaminated with foil and packaging waste. With the AirLift, Westeria®’s technicians and engineers have developed a unit that can be seamlessly integrated into existing systems. The AirLift system comprises three segments: The high speed transport belt, which feeds in the material at a speed of up to 4 metres per second. This is in turn connected to the AirWheel. We were able to rigorously build upon our years of experience in the wind sifter field in order to achieve clean separation of materials of virtually the same weight. And in conjunction with the AirWheel, the AirLift also perfectly demonstrates its abilities when processing PET bottles. Light plastics and label paper are perfectly separated. Wherever materials with a very similar, specific density need to be separated precisely, the AirLift is your ideal choice! Interested? Then speak to us!

Special challenges require special solutions. 

The Westeria® Windsifter AirTrack1 combines efficiency with lightness. Westeria®Fördertechnik consistently designed the Windsifter AirTrack1 for weight optimisation right from the planning phase. The resulting advantages are simple loading on lowbed trailers for shipping and deployment on uncompressed subsoil. The Windsifter AirTrack1 even has special discharge belt transfer heights so the accrued large material heaps don't need to be driven off so often. Windsifter technology from Westeria® in mobile and stationary design that also convinces with its retractable maintenance modules, guaranteeing faster and simplified service.

The Westeria® Windsifter AirTrack2 is the result of logical and consequent, continuous development of innovative Westeria® technology. With its generously dimensioned chain track chassis, the Windsifter AirTrack2 can be used on nearly every type of terrain. Its wide range of applications, from separating building waste to processing substitute fuels is what sets the Westeria® Windsifter AirTrack2 apart. Its powerful electromagnets ensure absolutely clean and efficient FE separation. 

Conclusion: powerful, mobile windsifter sorting system with great flexibility in the familiar Westeria® prime quality!

The mobile windsifter AirBasic® is the compact and economic solution made by Westeria®. The AirBasic® windsifter
 shows all its skills and advantages when you have to separate various types of waste such as construction waste, compost, household waste, slags or scrap material. In order to offer you a wide range of flexibility concerning the AirBasic®, we have provided it with numerous options. By adapting modular components, we have been able to reduce delivery time and production costs of the AirBasic® significantly. Depending upon your requirements you now can assemble your individual windsifter, as the AirBasic® is the logical result of a consequent and continuous development. Of course, the patented Westeria® 
windsifter technology is part of the attractive Westeria® product design.
