Blade Materials Match Application Martin Engineering’s urethane expertise provides blades to suit standard, high-temperature, or high-abrasion conditions. The Most Cleaner, the Least Investment Economical pre-cleaner and tensioner system combines effective cleaning, durable life, and low-maintenance requirements. NOTES Martin® QC1™ Cleaners are available for belts up to 120 in. (3048 mm) wide. For belts wider than 72 in. (2000 mm) a dualblade assembly is required. Normal blade length is belt width less 6 in. (150 mm). For belts with a 45° trough or where material is centered on belt, customer should consider a blade that is belt width less 12 in. (300 mm). This is because belt edges may not require cleaning, and blade-to-belt friction in these areas may lead to premature wear of cleaner and/or belt.
