Advanced Efficiency Hydraulic/Transmission Filter

Smart Cat equipment owners protect their machinery – and livelihood – when they
choose genuine Cat filtration products.

Cat Advanced Efficiency Hydraulic and Transmission Filters provide increased contamination control without giving up superior dirt-holding. Using improved filter media, our filters offer higher efficiency, improved capacity and lower pressure drop characteristics.

Pleat spacing is rigidly maintained by acrylic beading that prevents bunching and provides maximum filtration surface area throughout the life of the filter. In addition, the integrated seal ensures a separation between the clean and dirty sides of the element.

Cat Advanced Efficiency Hydraulic and Transmission Filters offer an increased level of protection offering the following benefits:

  • Unique filter media provides unsurpassed protection
  • Increased debris holding capability
  • Increased resistance to collapse
