DES-CASE (DC-BB) 2.75" x 3.25" Button Disposable Breather

  • As wet contaminated air is drawn through the unit, multiple 3-micron polyester filter elements remove solid particulate and the colour-indicating silica gel extracts moisture.
  • When air is expelled from the container, the top foam pad prevents oil mist from contacting silica gel or entering atmosphere.
  • Each breather is outfitted with a clear, rugged polycarbonate casing that allows easy view if colour-indicating desiccant in order to monitor when the breather should be replaced.
