Engineered for use in hydrostatic drives, compressors, converters, and return or exhaust lines, these spin-on filters deliver reliable performance even in harsh environments. Each filter is equipped with advanced "A" type elements made from reinforced inorganic microfibers, ensuring absolute filtration from 3 to 25 microns (βx ≥ 200) and exceptional resistance to deformation, distortion, and contaminant release. Built for easy replacement and long service life, the CSD Series offers a robust filtration solution for heavy-duty mobile and industrial machinery applications.
