Breathers: StandardsBasic protection from moisture and particulate contamination in lubricant and equipment
Standard Breathers:Typical Industries
• Power Generation• Mining• Aviation• Storage• Manufacturing• Petrochemical
How It Works:This breather unit 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.

By the Numbers:
1–Integrated Nylon StandpipeThe integrated standpipe provides excellent vibration re-sistance and dissipates impact throughout the unit, elimi-nating weak points. It also allows even airflow distribution throughout the unit, eliminating inaccurate readings of desiccant saturation.2–Resilient Polycarbonate BodyShock-absorbing, clear casing provides reliable service and easy maintenance.3–Filter ElementPolyester filter element removes airborne contamination to 3-micron absolute. Unique loops allow particles to releaseduring system exhalation, helping to increase breather life.4–Foam PadFoam filter captures any oil mist and disperses incomingair evenly over filtration and drying areas.5–Water Vapor AdsorbentSilica gel adsorbs water from incoming air and can hold upto 40% of its weight. Condition is indicated by change ofcolor from blue to light pink.6– Secondary Filter ElementSecond polyester filter element protects against migrationof desiccant dust, providing maximum efficiency.7–Threaded MountingEasily replaces standard filler/breather cap with multi-fitconnection or one of several adapters.8–Air VentsIndividual air intakes are opened based on flow require-ments of the system. Plugs protect unit during shippingand storage.
