3A-GM™-Oil Oil-Water Flocculation Separator: The GM™-Oil Oil-Water Flocculation Separator comes in two types: one for removing water from oil and another for removing oil from water. Both types have the common feature of separating the less abundant component from the more abundant material, achieving complete separation due to the density difference between water and oil, and the two-stage separation through the filter core. The Oil-Water Separator is also known as a separator, flocculator, or separator, etc.
