Description of function

Zeichnung Funktionsbeschreibung GN 552

Breather caps GN 552 are used in oil reservoirs which must be ventilated.

If the oil is agitated, e.g. by a gear running in an oil bath or sump, there is the risk that the 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 higher air flow rate is desired (coding 3 and 4).

A filter is used to protect the oil from outside pollution (dust). The filter is mounted behind the splash guards to ensure it makes no contact with the oil and becomes saturated by capillary effect.

For a very high air flow rate (the level of the oil reservoir changing quickly), Breather Caps GN 663 should be used.

GN 109 Level markings / Special lengths (special order)

GN 109

Level markings and special lengths GN 109 for oil dipsticks are available for the standards shown above. The dipstick is shortened to the length l1 and the marking notches are milled in at l2 or l3 with the effect that they are easily visible. The maximum length l1 is given in the appropriate standard. The length specifications l1 to l3 refer to the contact surface without seal, with a tolerance of ±1 mm to be taken into account. For critical applications and depending on standard, the seal must be taken into consideration with a thickness of as much as 2 mm.
If required, more than 2 notches may be cut which are then specified by the appropriate details on the position
(l4 ... lx). Also, texts such as MAX / MIN may be laser-engraved in addition to or instead of the notches by submitting the
appropriate template.

The level markings / special lengths GN 109 are to be ordered as a separate item in shopping cart step 1 under note.
