An air cleaner assembly, also known as an air filter assembly, is a crucial component in the air intake system of internal combustion small engines. Its primary function is to filter the air that enters the engine, ensuring that only clean air is delivered to the combustion chamber. This process is vital for engine performance, fuel efficiency, and overall longevity.
The air cleaner assembly plays a vital role in safeguarding the engine from contaminants that can cause premature wear and damage. By supplying clean air to the combustion chamber, it enables efficient fuel combustion, reduces emissions, and extends the lifespan of the engine.

Air Filter Element
The core component of the air cleaner assembly is the filter element. Typically made of paper, foam, or other filtration materials, the filter element traps dust, dirt, pollen, and other contaminants present in the air. Regular replacement of the filter is necessary to maintain optimal engine efficiency.
Air Cleaner Box
The air box, or air cleaner housing, encloses the filter element and provides protection from external elements. It is designed to prevent unfiltered air from entering the engine, ensuring that the air drawn into the system passes through the filter.
Inlet Duct
An inlet duct connects the air box to the external environment, allowing the intake of ambient air. The design of the inlet duct is crucial for optimizing airflow and preventing the entry of large particles that could damage the engine.
Seals and Gaskets
Seals and gaskets are integrated into the air cleaner assembly to prevent the leakage of unfiltered air. They ensure a tight seal between the various components, maintaining the effectiveness of the filtration process.
Housing Clips and Fasteners
Clips and fasteners secure the air box and other components, preventing them from coming loose due to engine vibrations or other external factors. These are essential for maintaining the integrity of the air cleaner assembly.
