Abstract
A flow system includes an air mover operable to cause the flow. A first stage, such as a coarse filter, is disposed upstream of the air mover and operates on the flow. A second stage, such as an adsorbent cell or muffler, is disposed downstream of the air mover and further operates on the flow. Other stages, such as a fine filter, may be disposed between the first and second stages.
