The sealing air connection is rotatable. The compressed air hose 4 × 0.75 is not
included in the scope of delivery.
Fig. 6-12: Connection compressed air hose for using sealing air.
NOTICE
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.
NOTICE
The compressed air gland is not closed upon delivery. Always operate motors
with compressed air connection with connected compressed air supply.
