4.2.14 Air-pressure connector kit
A defined over pressure can be conducted into the motor with an air-pressure
connector kit. Therewith, penetration of damaging liquids can be prevented. The
areas of application for sealing air are all installation locations in which humid
air or coolant can come into direct contact with the motors, especially in wet
processing rooms.
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.
The pressure air must be free from oil and dry, according to DIN ISO 8573-1
Class 3 (usually in pressure air nets).
