Complete bearing housing for the manual wiper on Hanovia medium-pressure ultraviolet disinfection systems, catalogued under part number 180016-01. The housing carries the hand-operated wiper shaft where it enters the chamber end and keeps it running true. Supplied complete with its bearing, seals and retaining hardware rather than as individual components. This is the manual-wiper version; systems with a motor-driven wiper take the automatic housing, which is a separate item — check which wiper type is fitted before ordering, as this is the difference between the two listings. Reference number 22661-0318.
