AirWash System
Combined dedusting and conveying system for plastic regrind recycling and separation.
Kongskilde’s AirWash™ system is a cutting-edge solution for cleaning and dedusting plastic regrind materials, enabling the simultaneous conveying and cleaning of plastic pellets and granules for recycling. This dedusting system stands out in the market as it efficiently combines material transport with an advanced air-cleaning process, optimizing both productivity and material quality.
The AirWash system utilizes a powerful blower to vacuum and convey plastic regrind materials from sources such as granulators or debagging stations directly to the AirWash separation cyclone. The AirWash creates vortexes within the system to separate and clean plastic regrind, allowing for immediate reuse or storage.

How the AirWash System Works for Material Dedusting and Recycling
Dust, fines, and labels reduce the value of plastic regrind and limit its applications. The AirWash removes these contaminants at the source using a combined blower and cyclone under vacuum. This keeps the process clean, ensures consistent output, and maximizes the quality and value of the recycled material.
the AirWash provides an efficient and economical solution for handling plastic regrind. This vacuum-based dedusting system uses a two-step cleaning process to achieve precise separation:
- Cyclone Separation: Material enters the separation cyclone, where air vortexes clean the plastic regrind, removing fines and impurities.
- Cascade Cleaning: In the cascade section, material falls by gravity through adjustable vacuum slots, ensuring thorough cleaning.
Once processed, the clean regrind can be reintroduced directly into the production line, making the AirWash system ideal for in-house recycling and consistent, high-quality material output.
Key Benefits
- Enhanced Reuse of Scrap: Maximizes recycling potential and reduces raw material costs.
- Easy integration: Connects directly to the granulator or grinder, without the need for a separate conveying system.
- Improved Production Cleanliness: Removes dust and fines, reducing facility cleanup requirements.
- Increased Material Throughput: Efficiently handles large volumes of plastic regrind.
- Higher Quality Regrind: Produces cleaner, more consistent regrind for seamless reintegration into production.
- Optimized Production Efficiency: Supports continuous operation, minimizing downtime.
Unique Features of the AirWash System
The AirWash system’s modular design and advanced features make it easy to integrate into existing production facilities and adjust to specific operational needs:
- Modular Components: Flexible installation options for easy integration.
- Swivel Hinge for Blower: Enables quick inspection, cleaning, and maintenance.
- Antistatic Eliminator: Optional antistatic feature near the material outlet for handling static-prone materials.
- Filter Bag Manifold: Available with collection drums for batch processing or for continuous operation.
- Optional Dust Cyclone with Airlock: Provides additional dust control when used with the filter bag manifold.
Anti-Static Eliminator
Static-prone materials can cause fine particles to cling to pipe walls and equipment surfaces during conveying, affecting both material cleanliness and system performance. The AirWash anti-static unit addresses this directly. Installed between the rotary valve and the baffle section, it uses ionized air to neutralize static charge as material falls through the pipe. With static removed before the material reaches the cascade section, dust separates more effectively and the regrind arrives cleaner.
