This is a secondary attachable belt scraper that retro-fits onto an already existing series 2000 unit.
It comes in both variants for flat and chevron belt. This would be used instead of installing another Series 2000 unit on the same conveyor.
Secondary Brush Cleaner
This is another secondary attachable unit that also fits to an existing Series 2000 unit. This product is cheaper that the tandem attachment.
This would be recommended for any small amount of dry material still getting by the Series 2000.
