What does a tank breather filter do?

Tank breathers are a type of filter that clean and protect fluids from moisture and particulate contamination as they are added to storage tanks, ensuring that air and moisture are dispersed from the system as levels of fluid change and the new air entering the system is filtered. Tank breathers will trap air particles before they have the opportunity to enter a tank, ensuring that the oil is kept clean, which will reduce the buildup of contaminants and cost of maintenance over time. Extending the working life span of the system.


Breathers are used as a protection device and are often mounted on the top of a nozzle opening of a storage tank, often replacing the standard dust cap. Our tank breathers are compatible with most synthetic oils, diesel, and most synthetic oils.
