1. Secondary Filter Element – Second polyester filter element protects against migration of desiccant dust, providing maximum efficiency.

2. Foam Pad – Foam filter captures any oil mist and disperses incoming air evenly over filtration and drying areas.

3. Integrated Nylon Standpipe – The integrated standpipe provides excellent vibration resistance and dissipates impact throughout the unit, eliminating weak points. It also allows even airflow distribution throughout the unit, eliminating inaccurate readings of desiccant saturation.

4. Water Vapour Absorbent – Silica gel adsorbs water from incoming air and can hold up to 40% of its weight. Condition is indicated by change of colour from blue to light pink.

5. Resilient Polycarbonate Body – Shock-absorbing, clear casing provides reliable service and easy maintenance.

6. Filter Element – Polyester filter element removes airborne contamination to 3-micron absolute. Unique loops allow particles to release during system exhalation, helping to increase breather life.

7. Air Vents – Individual air intakes are opened based on flow requirements of the system. Plugs protect unit during shipping and storage.

8. Thread Mounting – Easily replaces standard filler/breather cap with multi-fit connection or one of several adapters.

Standard Series Desiccant Breathers

As wet contaminated air is drawn through the desiccant breather 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 the atmosphere.

The desiccant breather replaces the standard dust cap or OEM breather cap on equipment. As air is drawn into equipment through the breather, the layered filter elements remove particulate while the desiccant beads strip harmful moisture. While in service or during shut-down, the desiccant beads attract moisture from inside the equipment reservoir, actively drying the equipment.

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