Abstract

The present invention relates to a filter unit for filtering a compressed gas contaminated with oil, in particular compressed air, wherein the filter unit contains a coalescence filter for coalescing the contaminant contained in the compressed gas, in particular oil. The coalescence filter comprises a housing with a gas supply for supplying the gas to a primary coalescence medium disposed in the housing, the gas flowing in a flow direction, wherein the primary coalescence medium contains at least one first layer of a first porous coalescence medium and a second layer of a second porous coalescence medium adjacent to the first layer, wherein the primary coalescence medium has a total thickness of at least 3.5 mm, measured at a pressure of 2 N/cm.
