There are two filter elements in one group for Coalescer-Separator filter: Coalescer filter element: mainly congregate the water molecule to make it to a liquid water.

Separator Filter element: separate the liquid water from the oil. Liquid water will be expelled. 

Coalesce-separator Filter Element: Removing impurities & water deeply

Fuel Water Separator Filter is processed by a special process by a variety of composite materials with hydrophilic characteristics, it can not only filter out mechanical impurities in the media, but also by coalescence, so from the media in the emulsified state's water separated, and the larger droplets coalesce to facilitate the further purification of the medium.
