The Durt Tracker Primary Cleaner is normally used along with at least one other secondary cleaner, such as the Durt Tracker Secondary Cleaner. For optimum results, it should be used with a water spray system. The Durt Tracker Primary Cleaner utilises an extruded polymer track and industrial urethane, designed to control costly material carry-back. It protects the secondary cleaner from being overpowered by excess material, thus increasing its effectiveness. The blade material is a 152mm-wide one-piece cast urethane. These segmented blades can be easily removed by sliding on and off the mainframe track. The cleaner is mono-directional, however, the cleaner will not be damaged by belt direction reversal. The cleaner is suitable for use on crowned head pulleys and damaged or grooved belts, while the urethane blades quickly conform to the belt profile.
