Professional-Grade Dual-Element Air Intake System

Air Filter Kit 40C4077

The Air Filter Kit 40C4077 is a professional-grade dual-element air intake filtration system engineered to provide clean, debris-free airflow to high-displacement diesel engines operating under severe industrial workloads.

The Air Filter Kit 40C4077 delivers absolute engine intake security by blocking ultra-fine dust, ambient soot, and silica particles from entering the combustion chamber. Precision-engineered as a direct factory substitute for GUANGXI LIUGONG Machinery 40C4077, Fleetguard AA90138, and HiFi Filter KA 18150, this heavy-duty radial-seal kit is fully optimized for the LiuGong 922E tracked excavator. Utilizing robust inner and outer support matrices, it ensures a perfect physical fit and uncompromised sealing integrity, drastically reducing engine friction and unexpected fleet downtime in harsh environments.

40C4077 Product Advantages

01	Dual-Element Multi-Stage Barrier Combines an outer primary filter for heavy particulate holding with a secondary inner safety element to eliminate bypass hazards during maintenance.
02	Precision Radial Seal Technology Features molded polyurethane end caps that maintain a resilient, vibration-proof seal against the factory canister walls under high vacuum.
03	Rigid Metal Outer Cage Support Reinforced with diamond-pattern structural steel mesh to prevent pleat bunching and physical collapsing during high-airflow operating phases.
