Oliver exclusively offers Westrup precleaners and fine cleaners.
The 2 Westrup seed cleaners have similar functions and the differences are the construction details, such as slanting of screens, single or double suction and configuration of screens.
The Pre cleaners have a larger area to remove coarse impurities ( scalping ), the fine cleaners in turn, seek to work more with minor impurities ( sifting ). We use the most rigorous rules for calculating capacity and we do not accept mediocre results.
Oliver / Westrup offers several models suitable for any capacity need. The Westrup seed cleaner equipment configurations take into consideration the characteristics of the client’s product, choosing the screen area and its distribution between scalping / sifting , physical space for installation and quality requirements.
The settings can be changed manually or electronically by electric motors (optional).
