Cleaning & Calibrating

Aspirator AS Selecta

The PETKUS Selecta AS Series sorts seeds on specific weight in a vertical air column, directly behind the vibrating feeder. The aspiration units can be used as stand alone units but can also be integrated in PETKUS Selecta cleaning, calibration and sorting machines.

Core Technology

The AS 1.1 is ideal for pre-cleaning of samples in plant breeding / seed test labs and is used on top of the spiral separators to operate both as a (pre-) cleaner and feeder.

The AS 2.5 is ideal for pre-cleaning of samples in plant breeding or even for final cleaning for breeding samples of heavy seeds. Used as a stand alone machine.

The AS 10.0 is the ideal machine to be used as a pre-cleaner in a seed-cleaning line for the bigger capacities or as stand-alone machine. Also available with a special feeder for difficult seeds like lettuce to remove the very light debris.
