ABSTRACT:
An air cleaner for a heavy duty vehicle comprises a container having an open end for receiving a filter cartridge, and a removable closure for the open end. The closure includes a first portion which defines a central opening which is removably secured to the open end by circumferentially spaced bolts and a second portion comprising an air valve housing which is mounted on the first portion through a swivel connection to permit the air valve housing to pivot relative to the container without removal of the bolts. The air valve housing includes a pair of inlets connected to different air sources, such as to ambient outside air and to heated engine air respectively, and a valve mechanism which opens one of the inlets while the other is closed. Air communicating through the open inlet is communicated through the central opening into the container.
