ELESA Original design Breather valve caps EN 552.1 are used for (low) container overpressure of 10 or 100 mbar.
The gasket prevents contamination of the fluid from outside (dust); an air filter is not required.
At the same time it is guaranteed that no fluid escapes, especially not in case of strongly moving fluid (oil splashes) or during transport.
