The Redekop KAS Pre-Cleaner is a high-efficiency airflow system engineered to increase threshing capacity, reduce rotor loss, and improve overall combine performance. Mounted at the front of the combine’s cleaning system, the KAS Pre-Cleaner uses targeted air velocity to separate light chaff and fines before they enter the main cleaning shoe — allowing your machine to focus on harvesting clean, high-quality grain.
By offloading debris early in the cleaning process, the KAS Pre-Cleaner enhances grain flow, reduces load on sieves, and helps operators maintain consistent performance in heavy-yielding or high-moisture crops. The result is greater capacity, cleaner grain, and less downtime — even in challenging harvest conditions.
Proven through field testing across a wide range of crops and combines, the KAS Pre-Cleaner is a smart, easy-to-install upgrade for farmers looking to push their equipment further without sacrificing grain quality or efficiency.
