Abstract
A filter to clean the air entering an alternator in a vehicle used in a dirty environment such as a crop harvesting machine includes a mesh filter which is coupled to an air intake of the alternator. The filter is constructed of a mesh material which is flexible and includes relatively small apertures. The apertures prevent chaff and other extraneous material from entering the alternator, while allowing air to flow freely into the alternator, preventing overheating. The flexible mesh sleeve can be vibrated during operation, as, for example, by the flow of air from the engine fan, to provide a self cleaning function in which the vibration causes extraneous material to be shook from the filter.
