Abstract
A filtering device for cleansing oil mist from an effluent flow includes a hollow casing containing a filtering media of packed particulate solids and channel means projecting into the media adapted to conduct an effluent flow to the media and disperse it therethrough whereby oil mist particles are retained in the media while the cleansed flow is admitted to the atmosphere. The particulate solids of the filtering media are of a material having an affinity for attracting and retaining oil and the material is disposed in successive layers such that the effluent must pass through a bed of graduated density whereby the filtering efficiency is enhanced.
