Hydraulic Filters for DT Cartridge

Every hydraulic system has suspended particles in its fluid.  Contaminants grind and wear at the surface of moving parts, introducing even more particles into the system. These contaminants cause more than 70% of system downtime.

High-performance DT cartridge filters provide better protection from particles and contaminant that reduce the effectiveness of lubricant and hydraulic fluid. Using Donaldson Synteq™ media technology, they deliver extended filter life, allow higher initial cleanliness and provide superior system protection.
