Product description

Information

For function and operational criteria of breather caps EN 663, see description of function.

Breather caps can be mounted either with a thread or a bayonet mount (BA) and can be combined with an EN 664 or EN 664.1 filler strainer.

The bayonet mount version can be secured against loss by means of the chain.

The dipstick has two flat sides on which the MIN-MAX markings can easily be applied (see GN 109).

Description of Function

Skizze Funktion GN 663

EN 663 breather caps are normally used in larger fluid containers, which must be vented and whose liquid level changes rapidly. The latter requires a high air flow rate during breathing / venting (for smaller containers and gears, Breather Caps EN 552 are usually sufficient).

If the fluid is moved, there is a risk of leakage. With properly arranged splash guards (see graph), these breather caps prevent fluid from leaking without substantially impairing the venting process (pressure compensation).

The splash guards can be left out if their function is not required or if a higher air flow rate is desired.

A filter is used to protect the fluid from external contamination (dust). It is made of PU foam with a grade of filtration of 40 µm. The filter in these breather caps has a large volume for a longer service life, i.e. it does not clog up as quickly.
