7.3 Sealing air connection
7.3.1 Description
Sealing air accessory kits enable the introduction of a defined overpressure
into the motor interior. This process reliably prevents the penetration of dam‐
aging liquids through endangered sealing points. Sealing air is used in all in‐
stallation locations where moisture or coolants come into direct contact with
the motors, especially in wet machining centers.
Damage due to liquid permanently present at the shaft sealing
ring!
The use of sealing air does not prevent the penetration of liquids
permanently present at the shaft sealing ring (e.g. in open trans‐
missions). Due to capillary effects, transmission oil can penetrate
the motors and cause damage despite the use of sealing air.
