Product description

Information

Function and operational criteria of breather caps GN 663, see description of function.

Breather caps can be connected by either a threaded or a bayonet (BA) fitting and filler strainer GN 664 or GN 664.1.

The bayonet type can be secured by means of the attached chain.

MAX-MIN markings can easily be added to the flats of a dipstick (see GN 109).

Description of function

Breather caps GN 663 are normally used in larger oil reservoirs which must be ventilated and whose level changes rapidly. The latter requires a high air flow rate during breathing / ventilating (Breather caps GN 552 are usually sufficient for smaller containers and gears).

If agitated, there is the risk that oil will leak. With properly aligned and shaped splash guards (see schematic drawing), these breather caps prevent the oil from leaking without substantially disrupting the ventilation / breathing process (pressure compensation)

The splash guards can be left out if their function is no longer needed or if a maximum air flow rate is desired.

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