EE 814 Air Filter

EE-814 Ultra High Efficiency Air Filter (Replaces CAT 128-2686)

Maximize the protection of your heavy machinery with the EE-814 Air Filter. Specifically designed to replace the Caterpillar 128-2686, this Ultra High Efficiency (UHE) primary filter is engineered for equipment operating in extreme environments. Whether you are working in mining, construction, or agriculture, the EE-814 provides a superior barrier against fine dust, soot, and silica.

The EE-814 features a Radial Seal design, ensuring a leak-proof fit that prevents unfiltered air from bypassing the media, even under high-vibration conditions.

Key Performance Features:

• Ultra High Efficiency (UHE): Advanced media captures significantly more microscopic particles than standard filters, extending the life of your engine.

• Radial Seal Technology: Provides a reliable, airtight seal to protect the engine intake from contaminants.

• Rugged Construction: Reinforced with corrosion-resistant steel liners to maintain structural integrity under high-airflow demands.

• Reduced Maintenance: High dirt-holding capacity means fewer filter changes and more uptime for your fleet.
