Whenever the pressure or fluid level inside a reservoir fluctuates, airborne contaminants such as dust/dirt, moisture, and oxygen from the ambient environment is drawn through the breather vent port.

These unwelcome contaminants expedite the oxidation of oil, increases humidity which leads to condensation and free water accumulation, causes oil emulsion, sludge and acid formation, and corrosion. This in turn results in frequent fluid and filter changes, increased operating costs and downtime, and shortened equipment life, which greatly increases maintenance costs.

For all applications using hydraulic fluid and/or oil contained within fluid reservoirs, the use of desiccant air breathers is commonplace and can prevent possible contamination of fluids by absorbing moisture and filtering out other airborne contaminants. The efficiency of the breather and competitive cost over the period in service is a key factor in selecting which breather to use.

Pulsarlube AIR® Desiccant Breathers are a highly efficient and proactive maintenance countermeasure. It is one of your must-haves not only to keep the entire fluid system sound and clean, but to also extend the storage and service life of fluids.
