EE 811 Air Filter

EE-811 Radial Seal Air Filter (Replaces Komatsu 424-01-H0P03)

Optimize your heavy machinery’s performance with the EE-811 Radial Seal Air Filter. This premium primary air element is specifically engineered for high-dust construction and mining environments. It serves as the first line of defense, ensuring that only purified air reaches your engine’s combustion chamber, thereby preventing premature wear on cylinders and pistons.

Designed to meet the rigorous demands of Komatsu Wheel Loaders, the EE-811 features a high-stability radial seal that prevents air bypass even under extreme vibration.

Key Performance Features:

• Radial Seal Technology: Provides a reliable, airtight seal that simplifies installation and resists leakage in high-vibration applications.

• High-Capacity Media: Advanced pleated paper design captures 99.9% of airborne contaminants including fine dust, soot, and silica.

• Reinforced Structure: Built with an inner and outer metal mesh liner for maximum structural integrity, preventing collapse under high-intake pressure.

• Corrosion Resistant: Heavy-duty end caps and liners are treated to withstand humid and harsh operating conditions.
