be installed in motors that have a factory-installed shaft
seal.
•
Seeping fluids can lead to damage to the motor. The
tightness of the motor seal is ensured only according to the
guidelines of the corresponding motor protection class.
7.2 Air-pressure Connector Kit
The standard international protection type (IP65) may not be sufficient
during operation under adverse conditions. High demands may be made
on the tightness of motor seals when the motors are used in areas where
oily lubricating coolants are used. For this field of application, we
recommend using sealing air for our motors.
A defined excess pressure in the motor interior induced by the air-
pressure connector kit reliably prevents the penetration of, for example,
seeping oil and coolant lubricants.

Air-pressure connector kits are available as an accessory for IndraDyn A
motors with frame sizes of 100, 130 and 160, as long the motor has a
flange socket for its power connection. They are attached by simply
replacing the motor flange socket cover.
