Choosing the CORRECT
Chaffer & Sieve
For Your working Conditions & Applicacations
We offer Loewen Chaffers & Sieves which are available in a complete range of original finger styles and air foil designs. Each option provides effective performance in certain crops and conditions. Which is the right one for you? The following are general guidelines to help narrow down the choices. For specific part numbers and pricing call 800-851-3014.
ADJUSTABLE (Peterson) AIR FOIL
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.
RIGID AIR FOIL
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.
ADJUSTABLE SHORT FINGER
Top chaffer is recommended for small grains, rice, flax or small seed. Bottom sieve is used in corn and beans.
ADJUSTABLE LONG FINGER
Designed for corn, beans and most other large seed crops. Less plugging with cobs and debris will occur with this chaffer.
ADJUSTABLE BLUNT FINGER
This bottom sieve is used in most crops.
ROUND HOLE
This bottom sieve is available in a variety of hole sizes and is specific to the crop being harvested. For use in crops from alfalfa and clover to beans and corn.
