  • AIR CLEANER ASSEMBLY AND FILTER ELEMENT PROVIDING IMPROVED DYNAMIC WALL STIFFNESS
    Publication number: 20130305930
    Abstract: An air cleaner assembly and a filter element reduce wall noise by rigidly coupling the movement of opposing air cleaner housing sidewalls through the installed filter element. The sidewalls are rigidly coupled through the filter element with the sidewalls coupled to move together in unison such that wall deflection forces created by the pressure pulsations tend to cancel each resulting in improved dynamic stiffening of the air cleaner walls and reduced wall noise.
