Don't need to use it, they just can. By using a centrifuge they force the contaminants and water to separate from the grease (IE different weights....common use is to separate blood). Just another way to end up with clean usable product that is fairly fast. Settling time and filtering is the most common method, slow but inexpensive. Most people don't have a centrifuge in their tool bag.
