Special Features:

Water vapor adsorbent-thesilica gel used adsorbs up to 40% of its own weight; bi-directional air flow-360 degrees air flow allows air to be breathed in and out as fluid level changes or differential pressures occur; color indicator- when adsorption is reached the silica gel turns from gold to dark green, indicating replacement is needed; activated carbon-as asir is expelled, it passes through activated carbon which removes oil vapor, fumes, and odors; dual filtration system- a two micron filter is located at the top and bottom of the silica gel bed, the top filter removes particle contamination froma atmospheric air and the bottom helps wit dust created b the silica gel beads contacting each other; height (2 inches); diameter; (2 inches) ; connection size: 1/2" female npt

Properties:

A mechanical device designed to permit a free flow of air into and out of an enclosure, usually used on engine crankcase, vehicular differentials and transmissions, pumps, compressors, and the like. see also cap, vent, fuel storage tank. excludes ventalator (as modified).
