Abstract: An air cleaner assembly includes a precleaner assembly. In one aspect, the precleaner assembly incudes a bypass arrangement that is operated to bypass a portion of air around the precleaner assembly. The bypass arrangement can be operated by a controller based on at least one input signal corresponding to one or more of a vehicle speed, a vehicle engine speed, a vehicle engine load, an operator input, a vehicle location, an air pressure drop across a filter element, an air pressure drop across the precleaner assembly, an acoustic level, a vibration level, a change or cleaning frequency of the filter element, a total number of filter element changes, an identity of the filter element, an identity of the engine, an identity of the vehicle, an air flow rate through the precleaner assembly or through the filter element, and a weather condition parameter identified through data received locally or from a weather service.
