The Wacker Neuson 4238-400-1301 Air Cleaner is a genuine OEM component designed for the BFS 2020AS floor saw. As a direct OEM replacement, this part is manufactured to the exact specifications required by Wacker Neuson, ensuring it seats and seals correctly within the engine's air intake system. This is the same air cleaner supplied with the machine at the factory, so fitment on the BFS 2020AS is confirmed. Keeping a clean, properly functioning air cleaner in place protects the engine and maintains consistent cutting performance on the job.
Key Features
- Genuine OEM Filtration Media — Built to the same filtration efficiency specification as the original, so the engine receives properly cleaned air at the correct flow rate.
- Drop-In Installation — Matches the original mounting interface on the BFS 2020AS exactly, seating and securing without any modification to the airbox or housing.
- Confirmed BFS 2020AS Fitment — Verified for the BFS 2020AS floor saw; use part number 4238-400-1301 to confirm you have the correct unit before ordering.
- Engine Protection Under Cutting Conditions — Floor saws operate in high-dust environments; a correctly sized OEM air cleaner prevents abrasive particles from reaching the engine's intake, protecting cylinder walls and rings over time.
- Maintains Engine Breathing Efficiency — A clogged or ill-fitting air cleaner restricts airflow and richens the fuel mixture, causing hard starting, power loss, and increased fuel consumption — this OEM unit restores correct engine breathing.
The air cleaner filters incoming air before it enters the engine's carburetor or intake manifold, removing dust, grit, and debris that would otherwise cause rapid internal wear. On a floor saw like the BFS 2020AS, which regularly operates in concrete dust and aggregate debris, a functioning air cleaner is critical to engine longevity and consistent power output. When the air cleaner becomes clogged or damaged, airflow is restricted, engine performance drops, and internal components are left vulnerable to abrasive contamination.
