Replacing the standard breather cap with a hygroscopic breather will eliminate the ingression of moisture and particles through the reservoir's vent. These breathers combine a woven-polyester media that filters particles as small as 3 microns, with silica gel desiccant to remove water vapor from incoming air. The result is relative humidity levels within the reservoir headspace that make condensation unlikely, therefore reducing water contamination of the oil.
The desiccant crystals are chemically inert, non-toxic, and non-corrosive. Color change of the crystals indicates when it is time to replace the breather, which can be disposed of as solid waste.
The benefits of installing a hygroscopic breather include:
- Elimination of headspace condensation
- Reduction in water contamination of the oil
- Reduced sludge deposits
- Reduced particle ingression
- Prolonged oil, filter and machine service life
