Exterra® Secondary Belt Cleaner

Second to none

Unlike primary precleaners, Exterra Secondary Belt Cleaners accommodate greater levels of tension since the belt is clear of interference from the head pulley.

When a primary scraper leaves behind more carryback material than you can stand, consider installing a secondary cleaning system behind the drive pulley. Together, primary and secondary belt scrapers will remove at least 90% of all carryback material and usually much, much more.
