7.1 Sealing air connection
Use of the motor under unfavorable conditions may require a higher degree
of protection than provided by the radial shaft sealing ring (IP65). This is par‐
ticularly true when using the motors in areas with higher demands regarding
tightness of the motors due to the use of coolants containing oil. For this area
of application, use of sealing air is recommended in addition to the radial
shaft sealing ring.
By means of a defined overpressure introduced into the motor via the sealing
air connection, ingress of creep oils and coolant is reliably prevented.
