Innovative and compact

AirStar
Efficient separation

The AirStar uses a unique, patented Westeria system that offers the highest aerodynamic efficiency and allows a throughput of up to 400 m³/h.

The sophisticated design of our air nozzles allows us to produce a precise, uniform airflow for perfect separation results. In doing so, we can achieve a 60% higher core jet speed than comparable air classifiers and even consume less energy.

The windsifter
for best separation results

Hundreds of customers around the world can confirm that the AirStar delivers what it promises: best separation results, low and easy maintenance, reliable and durable.

The flexible AirStar is available in different versions. Working widths of 1000 – 3000 mm and different sizes of the lightweight material chamber allow the windsifter to be flexibly integrated into any plant. Optionally, our AirLift can be integrated to save space and separate an additional “ultra-light” fraction.

All components of the separator are easily and individually adjustable and accessible to facilitate maintenance. Thanks to the modular design, the machine is easy to customise, can be transported in a space-saving way and can be assembled in just one day.

Your benefit is our innovations
from over 30 years of development.
