AirStar evolution
Efficient separation
The AirStar evolution redefines wind sifting: efficient, user-friendly, and flexible for every recycling process.
It combines state-of-the-art technology with decades of Westeria experience and offers optimal accessibility and full process control thanks to its completely redesigned design.
The revolutionary NotusAir system ensures precise airflow control with minimal energy consumption – with reduced filter size.
Thanks to modular extensions and optional DuoDrum technology, the AirStar evolution can be perfectly adapted to individual material flows – for even cleaner fractions and maximum profitability.
A system that sets standards: robust, compact, and ready for tomorrow’s challenges.
NotusAir® Luftmanagementystem
Our newly developed NotusAir® air management system ensures significantly better separation with reduced exhaust air volume. With intelligent airflow design and innovative nozzle technology, NotusAir® is a prime example of our innovative spirit.
Perfect material separation with industry-leading quality
Reduced filter size
Minimal pressure loss thanks to aerodynamically optimized components
Minimal pressure loss thanks to aerodynamically optimized components
Frequency-controlled fan as an essential separation parameter
Less material loss thanks to controlled air recirculation with a special extractor hood
Intuitive control
Full control, self-explanatory operation
With the new Westeria user interface, you no longer need to rely on specialists. All parameters, such as drum positions, feed belt height, air speed, and nozzle angle, can be adjusted centrally using intuitive symbols.
Some of the programs are preconfigured by our experts and precisely tailored to your material, so that no major programming changes are necessary on site.

DuoDrum® – the third faction
The challenge: When conveying moist material or material with a high film content, separating it into two fractions is often not enough to achieve a perfect result.
The solution: DuoDrum® supplements the classic separation into heavy and light fractions with a medium fraction. This allows you to achieve a significantly cleaner separation even with difficult separation tasks.
• Integrated NotusAir® system: Two nozzles with precise, demand-driven air flow • Patented: Electronically adjustable additional drum for easy adjustment, both vertically and horizontally

DiscSpreader® – perfekte Materialverteilung
Patented and unique: the DiscSpreader® ensures even material distribution – regardless of moisture or feed. With two rotating discs, it conveys the material quickly, reliably, and in a space-saving manner. Only with Westeria can you secure this advantage in wind sifting.
• Higher separation quality thanks to even distribution
• Space-saving thanks to patented compact solution

DiscSpreader ®
NEW: 4-fold separation in just one machine
AirLift® – Ultra-lightweight materials
under control
Integrated as an additional stage, the patented AirLift® specifically extracts the ultra-light fraction (e.g., films) from the material stream. In combination with the DuoDrum®, this makes quadruple separation possible with just one machine for the first time. The newly developed AirWheel® air separator used for this purpose automatically detects blockages.
• Maximum separation efficiency thanks to the diametrical downflow principle
• Convenient maintenance access during operation
