OCA▪bag
oil contamination absorbing liquid filter bag
OCA▪bag filters are specially designed for separation of non-emulsified oils and hydrocarbons from water and other aqueous carrying liquids.
OCA▪bag filters has an excessive filtration surface area and dirt loading capacity due to a multi-layer technology, which results in true graded-density filtration, providing significantly increased loading capacities for absorbed oil and /or hydrocarbons.
