Damage due to permanent existing liquid on the
shaft sealing ring!
The use of sealing air does not prevent the penetration of continuously existing
liquid on the shaft sealing ring (e.g. for open gearboxes). Due to capillary action,
gearbox oil can penetrate into the motor and damage it, despite using sealing
air.
Damage due to ingress of dirt!
The compressed air gland is not closed upon delivery. Always operate motors
with compressed air connection with connected compressed air supply.
