Filters are the front line of protection for engine systems, removing contaminants from oil, fuel, coolant and air before they can cause wear or blockage. This group covers oil filters, primary and secondary fuel filters, water separators, air filter elements, coolant filters, hydraulic filters, and the filter heads that carry them. CAT specifies coolant filters containing supplemental coolant additive on many engines, which release corrosion and cavitation inhibitors into the coolant as they work; missing these at service leaves the engine unprotected even when the coolant itself looks clean. Filter change intervals on CAT engines vary considerably with duty cycle and fuel quality, so severe-service applications warrant shorter intervals than the standard schedule.
AMS Parts supplies a wide range of filters components for CAT engines used in power generation, marine, and industrial applications. Browse the full range below, or contact us for specific requirements.

As well as filtering, many CAT coolant filters release supplemental coolant additive into the system, maintaining protection against corrosion and liner cavitation.
No. Filters differ in filtration rating, bypass valve setting and burst pressure. A filter that screws on is not necessarily suitable for the application.
Follow the CAT schedule adjusted for duty cycle. Dusty conditions, poor fuel quality and heavy idling all shorten the safe interval.
