Product Overview
The NAKATU AF25667 AF26114 is a dual-element engine air filter set designed for compatible heavy-duty construction machinery, commercial trucks and industrial diesel engines.
The primary element helps capture dust, dirt and airborne particles before they enter the engine intake system. The secondary safety element provides an additional protective barrier, particularly during primary filter servicing.
Key Features
  • Dual-element configuration with primary and secondary air filters.
  • Radial-seal design for compatible air cleaner housings.
  • Helps reduce airborne dust entering the engine intake system.
  • Applicable Regions: North America, Europe, South America, Southeast Asia, and South Pacific.
Applications
The AF25667 and AF26114 combination is referenced for selected Komatsu construction machinery, including PC200-8 and PC220-8 excavators and PC290-8 excavators.
The corresponding Komatsu reference components are 600-185-4110 for the primary element and 600-185-4120 for the secondary safety element. The combined air filter kit is referenced as 600-185-4100.
Additional published applications include selected Freightliner FL60, FL70, FL80, M2 and Cascadia commercial trucks with compatible air cleaner assemblies.
Equipment compatibility depends on machine serial number, engine configuration, production year and air cleaner housing. Both elements must match the original installation requirements.
