Reservoir Breather, Standard, 40 Micron Rating, Nickel-Chrome-Plated Steel, 3.0" Outside Dia.

Breather caps for hydraulic tanks (sometimes called breather vents) allow air and moisture to exit the tank as the fluid level in the tank rises, helping to eliminate air bubbles and moisture that can affect system performance. They also filter ambient air that is pulled into the tank as fluid levels in the tank fall to prevent airborne contaminants from entering the system. These breathers are not suitable for filling tanks.

Hydraulic tank filler and breather filters clean hydraulic fluid as it is added to a tank, allow air and moisture to exit the system as fluid levels change, and filter air that re-enters the system. Filtering returning air traps airborne particles before they can enter the tank, keeping oil clean, reducing maintenance and extending the life span of the system. Hydraulic tank filtration keeps fluid clean and free from debris, water, and air. Clean hydraulic fluid reduces contaminant buildup and maintenance costs, and extends the working life of the system.
