Extreme Duty Desiccant Breathers

Secondary Filter Element – Second particulate filter element protects against migration of desiccant.
Visual Indicator – Windows on two sides of breather allow for easy monitoring of desiccant.
Water Vapour Adsorbent – Colour-indicating silica gel adsorbs water from incoming air. Replace when colour changes from blue to pink.
Rugged Housing
Integrated Standpipe – Resilient construction provides durability and allows oil mist to coalesce and drain back into the reservoir.
Foam Pad – Foam filter captures any oil mist and disperses incoming air evenly over filtration and drying areas.
Quad Check-Valves – Check-valves provide system pressurization, protecting system integrity and extending product life.
Filter Element – ePTFE filter removes airborne contamination to 0.3-micron absolute. Stops free water.

Extreme Duty Desiccant Breathers

The Des-Case Extreme Duty (XD) desiccant breather has excellent vibration and impact resistance, can withstand broad temperature ranges, has expansive chemical compatibility, and features quality check valve technology while still accommodating higher air flow. The Extreme Duty breather also has the best filter efficiency of any Des-Case breather―down to 0.3µ absolute (β0.3≥200).

As wet, contaminated air is drawn through the unit, multiple 0.3 micron filter elements remove solid particulate while 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 the atmosphere.

Seeing pink? A pink breather means it has done its job keeping moisture out of your lubricants. Time to replace the breather with a new one.
