Purge Air System
The purge air system protects the drive and guides of the L-417.xx9211E1B against
surrounding dust.
The purge air system comprises the following subassembly (subassemblies):
Passive dust protection
The passive dust protection consists of covering strips that seal the openings on the side of
the L-417.xx9211E1B's base body and therefore reduces the amount of dust that can
penetrate.
Active dust protection
The active dust protection consists of a purge air connector on the base body of the
L-417.xx9211E1B, which creates a slight overpressure in the L-417.xx9211E1B and therefore
reduces the amount of dust that can penetrate.
