Abstract: A filter element includes a bottom open end joined to a center tube opposite the top open end. The bottom open end defines a radially outer surface and a radially inner surface that is in communication with the central reservoir of the filter element. A locking feature is disposed proximate to the bottom open end. The locking feature includes an entrance slot that is disposed on the radially inner surface of the center tube extending axially from the bottom open end.

Abstract: A filter for filter air for an internal combustion engine and methods of operation are described herein. The air precleaner is configured to use electrostatic attraction or repulsion to move ionized particles towards an inner wall of the air precleaner, where the particles eventually exit the air precleaner through a particle exhaust. The particles are ionized using a positive charge plate and a negative charge plate. The positive charge plate creates a positive charge field, creating positive ions that ionize particles in the air with a positive charge. The negative charge plate creates a negative charge field, creating negative ions that ionize particles in the air with a negative charge. The air precleaner can also include a cyclonic section that causes the air to rotate about a central axis of the air precleaner, imparting a centripetal force on the particles. The centripetal force and the electrostatic force act together to filter the air.
