Sealing air connection
3.7.4
Ingress of fluids or dust at different temperature ranges can be pre-
vented by a separate sealing air connection with a defined overpres-
sure. The overpressure is achieved by connection to a regulated
compressed air system. It is installed together with an radial shaft-
sealing ring.
A sealing air connection is recommended for:
• Critical installation locations with extreme dust exposure
• Motors with permanent and direct fluid contact
Important
In the horizontal installation position IM V3, liquid can accumulate
permanently on the motor flange and penetrate into the motor. Even
a sealing air connection cannot completely prevent the liquid from
entering.
An air hose provided by the customer must be connected to a suit-
able regulated pressure reducer. The compressed air must be free
of oil and dust.
