Air separator for polymers and plastics
In the polymer and plastics industry, ensuring the removal of fine dust particles and long streamers from pellets is crucial before packaging and loading. This challenge requires a reliable separation solution to maintain product quality and operational efficiency.

Efficiently separate dust and streamers from pellets
The KWS Cascade Air Separator by Zeppelin Systems is designed for high-efficiency separation of fine dust particles and long streamers from polymer and plastic pellets. Capable of handling up to 200 metric tons per hour, this separator operates without the need for intake or discharge feeders. Utilizing gravimetric feeding, the pellets are fed into the separator where they fall through a series of rotationally symmetrical cascades. The counterflow principle ensures dust and debris are cleanly separated and extracted at the top of the separator with air. Its circular cross-section design eliminates dead spaces, reducing the risk of material mixing and ensuring consistent separation efficiency. Maintenance requirements are minimal due to the absence of rotating or wearing parts, making it a cost-effective solution for continuous operation.
Benefits
- Maintenance-free operation without rotating parts
- Consistent and high separation efficiency
- Gentle handling of product without height constraint
- Eliminates risk of product mixing with dead space-free design
- Easy setup and installation
