Abstract
The present disclosure describes a dry air breather assembly adapted to be readily mountable over the breather ports of devices which are intolerant of intake air having high relative humidities in excess of a predetermined level. Such devices include the Winchester Hard Disk Unit in which the deposition of excess moisture on the read/write heads and magnetic disk media is particularly detrimental. The present assembly includes a unique elongated, low-profile enclosure for the efficient and effective use of a desiccant having a high moisture removal capability at relative humidities above the predetermined level, and low moisture removal capability, below the level.
