Abstract: An air cleaner is illustrated having a transverse support carrying an eliminator blade assembled in a raised position above a downwardly inclined housing bottom. A means is provided for creating a seal for preventing the passage of air in the space beneath the eliminator blade assembled so as to bypass the eliminator utilizing a controlled level of liquid to establish the seal.
