Not Using Cat® Filters Might Come Back To Haunt You

Just like your Cat® machine performs better with genuine Cat parts, it also performs better with Cat filters and fluids. In fact, the only way to achieve peak performance is with Cat filters and fluids — they not only improve performance, but they also protect vital engine and hydraulic components, ensuring a longer life and higher resale value.

Why Are Cat Filters Better For You?

Only Cat filters are manufactured to the exacting specifications of your Cat machine—that’s why only Cat filters can improve your bottom line. We test them thoroughly in the lab and in the field to make sure you get the best filtration in the business.

Better For Your Bottom Line

We don't just test filters the traditional way; we test them the Caterpillar way.
These tests revealed that Cat filters:

  • Help Cat fuel injectors last 45% longer than when using a competitive filter
  • Can decrease the cost per hour up to 80%
80% savings with Cat Fuel Filters

Better Results

Five filters were tested and only one — the Cat filter — reached the end of the test before fuel injector failure. In fact, injectors with competitive filters experienced:

  • A leakage rate three times that of new
  • Significant erosion and leak paths
  • High levels of contaminants passing through
Better results vs the competitors

Better Testing

Our testing involves:

  • Using actual machine components (cylinder head, injectors, pump and other Cat fuel system components)
  • Circulating fuel through a C9 engine fuel system test rig
  • Running the rig at high idle speeds

Take a Look Inside and the Difference is Clear

Other brands may fit, but Cat filters protect your engine, drive train, hydraulic systems and components better. Our advanced design delivers maximum filtration efficiency and protection for your machine. For you, that means more uptime and lower owning and operating costs.

A. No Flexing

Spiral roving eliminates pleat movement and keeps contaminants from working their way into the clean side of the filter. Testing shows filters with spiral roving have 45% lower particle counts than others. Other brands often flex as fluid travels through them, releasing contaminants that can cause wear.

B. No Bunching

Acrylic beads rigidly maintain pleat spacing and maximize the filter's surface area — capturing and holding contaminants until the required change interval. Pleat bunching is common in other brands, allowing contaminants to circulate, cause clogging and shorten filter life.

C. No Metal Contamination

Fiberglass-reinforced nylon center tubes eliminate metal contamination and are 30% stronger than metal tubes, helping prevent collapse during pressure spikes or cold starts. In other brands, metal center tubes often carry metal contaminants left over from manufacturing, which can cause wear.

D. No Gaps

Molded end caps completely seal the clean side from the dirty side, eliminating gaps and keeping contaminants where they belong. Other brands have metal end caps glued on top of filter pleats — creating gaps that allow contaminants to reenter from the clean side.

The Best Machines Need the Best Filters

Why risk your investment by using non Cat filters and fluids? Only Cat filters and fluids are developed, tested and approved to the exacting standards of Cat equipment. They are a key element in machine health and are readily available through the Cat dealer network and online at 24 hours a day.

Air Filters

Safeguarding your Cat equipment from the dirt and contaminants created by the work environment is critical to component life and operator health and safety. There are three types of Cat Air Filters: Engine Air Filters, Cab Air Filters and Turbine Precleaners.

Cat Air Filters
  • Provide maximum protection of vital engine parts and optimum performance
  • Reduce airborne irritants, creating a cleaner, more comfortable operator environment
  • Offer increased airflow with less restriction
  • Deliver the most advanced filtration available, even with limited space constraints
  • Are environmentally friendly and incinerable

Cat offers multiple filter efficiencies depending on your machine and application. Talk to your Cat dealer to find the right solution for your needs.
