EE 819 Air Filter

EE-819 Ultra High Efficiency Air Filter (Replaces CAT 142-1340)

Maximize your heavy machinery’s uptime and protect your engine from the harshest environments with the EE-819 Air Filter. This Ultra High Efficiency (UHE) primary filter is specifically engineered for high-dust and heavy-load applications, providing superior filtration that standard filters can’t match.

Replacing the Caterpillar 142-1340, the EE-819 is designed for large-bore engines (like the CAT C9, C13, C15, and 3406C). It features a radial seal design and advanced media that can last up to six times longer than standard alternatives by capturing microscopic soot and fine dust before they reach your engine.

Key Performance Features:

• Ultra-High Efficiency: Specialized filtration media designed to handle extremely fine dust and heavy soot.1

• Radial Seal Technology: Ensures a consistent, leak-proof seal even under high-vibration conditions.

• Increased Dirt-Holding Capacity: Dramatically extends service intervals, reducing maintenance costs and downtime.

• Engine Protection: Significantly reduces internal component wear, extending the life of your turbocharger and engine.
