Abstract
The present invention relates to a coalescence filter for purifying a fluid which contains a carrier and at least one liquid contaminant, by coalescing of the at least one contaminant. The coalescence filter comprises an inlet for supplying the fluid to a filter element present in the coalescence filter. The filter element comprises a primary coalescence medium which is provided for coalescing of the at least one contaminant in the primary coalescence medium. The coalescence filter further comprises an outlet for discharging the coalesced contaminant from the filter element. The primary coalescence medium comprises at least one layer of a porous material, and has a total thickness of at least 3.5 mm, preferably at least 4 mm, preferably at least 5 mm, more preferably at least 6 mm, most preferably at least 7 mm, in particular at least 7.5 mm, measured at a pressure of 2N/cm2.
