We developed dual-zone 12-stage damping systems for our Ultra-Platinum, Ultra-Diamond, MAXXUM-Ultra and OLYMPUS-Ultra filters. None are identical. Each is designed to function exclusively with its associated architecture and damped in accord with tolerances of 1 to 10 thousandths of an inch. Inside each of the above-mentioned filters are 3 fixed damping plates. These are located on the base plate of the filter, the resting area of the filter upon which the component is placed, and the interior plate below the resting area of the filter. The remaining 8 internal damping stages are arranged in 4 zones below and 4 zones above an elastomer. The elastomer, of course, serves to lower natural frequency. Each of the 8 internal damping stages is precisely calculated thicknesses of aluminum alloy and acrylic damping materials or precisely calculated thicknesses of aluminum alloy, copper alloy, and acrylic damping material. There is an important reason why we use very specific metal alloys, elastomers, and acrylic damping materials.
