Purge Air Supply - Rotoclear S3 Instruction Manual

INSTRUCTION MANUAL
Finally, check the mechanical freewheeling of the
rotor by rotating it by hand.
The rotor is equipped with rare earth magnets.
Due to the strong magnetic fields, chips and parti-
cles may adhere to the inside of the rotor.
Chips and magnetic particles can be collected
from the rotor disc with a commercially available
holding magnet.
Clean the rotor disc to remove any adhering parti-
cles and chips before reassembling the rotor.

Purge air supply

A purge air supply is required to fulfil the Rotoclear
seal guarantee and is provided as standard for the
bonding and screw-mounting methods.
The suction effect of the rotating window creates
an air flow that prevents cooling lubricant from en-
tering the unit under moderate conditions inside
the machine tool.
This means that the unit (e.g. if retrofitted or con-
verted) can also be operated without a purge air
supply under moderate conditions.
If it is not possible to provide a purge air supply
(e.g. when retrofitting or converting a machine),
the unit can also be operated without a purge air
supply under moderate conditions.
Air must be able to flow freely through the con-
nection box and the protective hose to allow the
air flow to circulate.
Installation with purge air
(Rotoclear seal guarantee)
The purge air is fed into the system through the
purge air line (Fig. 10-G) via the plug-in connection
(Fig. 10-H) on the electric-pneumatic adapter and
supplied to the unit through the protective hose.
The purge air prevents the ingress of cooling lu-
bricants, oils or other liquid media. Purge air must
always be connected to maintain the Rotoclear
seal guarantee. The air pressure must be individ-
ually adjusted due to the different possible sizes of
supply lines.
