Hydraulic & Transmission Filters
Cat® Hydraulic and Transmission Filters are designed to maximize system cleanliness, and provide the best machine performance and component protection.
Due to the differences between the Hydraulic and Transmission systems, it’s important to choose the right filter for each system.
Cat Hydraulic Filters
The key to extending hydraulic and power train component life is to reduce contamination. Choosing the correct Cat® filter is essential in minimizing damage to components from abrasives. We offer Standard, Advanced, and Ultra High Efficiency (UHE) Filters to best meet machine and application needs:
- Standard Efficiency Filters are largely for older machines, where tolerances were more forgiving. Designed to maintain system cleanliness in most general and light duty applications.
- Advanced Efficiency Filters have increased contamination control without giving up dirt-holding capacity for stricter component and emission requirements in newer machines. It’s an upgrade from standard filters to provide an increased level of protection against accelerated wear with a special filter media to provide greater protection in moderate to severe conditions.
- UHE Filters provide optimum contamination control in all applications while still maintaining capacity. The filter’s super-fine synthetic media removes a higher proportion of fine particles for optimum contamination control in moderate and severe applications. Ultra High Efficiency Filters are recommended as a clean-out filter after any service work.
Cat Transmission FiltersCat transmission filters are designed to minimize cold start by-pass while maintaining appropriate cleanliness levels. They feature a synthetic media designed to deliver a high level of filtration performance and to reduce pressure drop across the media. Cat transmission filters have a significantly higher dirt holding capacity and perform better in cold weather.
With tighter tolerances in today’s engine component design, it is very important to properly address cleanliness levels. Caterpillar engineers the best protection into all Cat filters, resulting in higher efficiency filtration, longer system life, greater reliability and improved machine productivity.
