The Arm Cleaner, like the T-Cleaner, is a fines cleaner fitted onto the underside of the belt, immediately behind the drive pulley. The scraper elements are fitted so that they overlap one another, reducing the risk of streaking. The hard metal blades are mounted on an arm that is fixed into a rubber body, providing individual flexibility.

A spring tensioner provides the correct applied pressure for the entire life of the cleaner. The metal blades are more suited for higher temperatures and belt speeds than other types of cleaner blades.
