The unique, curved Air Foil louver design directs air virtually straight up, creating a cushion that floats material towards the back of the combine. High air volume provides a clean sample and helps to remove straw and stems. The adjustable air foil performs well in all crops, including grasses and small seeds.

Note: Not recommended for harvesting high moisture corn as silks may catch on fingers and cause plugging.
This non-adjustable top chaffer is pre-set for maximum performance under normal conditions. Best results in cereals and large seed crops. Loewen Rigid Air Foil Chaffers also feature welded in dividers which add rigidity and strength, and retain even distribution on hillside conditions.

Note: As chaffer is non-adjustable, control is limited to fan speed only.
