Case Backhoe Air Filter Kit | Parts 128782A1 & 128781A1

Product Overview

The Case Air Filter Kit includes the 128782A1 Outer (Primary) Filter and the 128781A1 Inner (Safety) Filter. This dual-element system is designed to provide maximum engine protection for backhoes operating in high-dust construction and utility environments. The outer filter captures the majority of airborne particulates, while the inner safety filter serves as a critical backup to prevent contaminants from entering the intake during primary filter servicing.

This kit is a standard maintenance requirement for a wide range of Case 580 and 590 Series backhoe loaders. It is specifically engineered for L-Series, M-Series, and SL-Series machines. Using high-quality replacement filters ensures optimal airflow, which is essential for maintaining engine horsepower and fuel efficiency in these hardworking diesel machines.
