The Wacker Neuson Air Cleaner Assembly is a genuine OEM component designed for BFS18, BFS20, BFSX18, and BFSX20 series floor saws. Sourced directly from Wacker Neuson, this assembly meets the exact specifications of the original part it replaces, ensuring a direct, hassle-free installation. Compatible across both standard and diamond series floor saw models, the is the correct replacement when your air filtration system needs servicing or renewal.
Key Features
- OEM-Matched Filtration Spec — Manufactured to the same airflow and filtration standards as the original, maintaining correct air-to-fuel ratios for consistent engine performance.
- Drop-In Assembly Replacement — Supplied as a complete assembly, swapping out directly into the existing mounting position on your floor saw without additional hardware.
- Broad BFS and BFSX Series Coverage — Fits BFS18D, BFS18, BFS20D, BFS20, BFSX18D, BFSX18, BFSX20D, and BFSX20 floor saw models from Wacker Neuson.
- Protects Engine Longevity — A correctly functioning air cleaner keeps dust and debris out of the combustion chamber — critical on concrete cutting sites where airborne particulate is heavy.
- Genuine Wacker Neuson OEM Part — Carries the full Wacker Neuson OEM designation, so you know the fit, form, and function match what left the factory originally.
The air cleaner assembly is the engine's first line of defense against dust, debris, and airborne particles — all of which are present in high concentrations during concrete and asphalt cutting operations. It filters incoming air before it enters the carburetor and combustion chamber, ensuring a clean air supply that allows the engine to run efficiently and reliably. When the air cleaner becomes clogged, torn, or fails, unfiltered air enters the engine, accelerating internal wear and causing rough running, loss of power, or hard starting.
