The Wacker Neuson Pre Filter is a genuine OEM component designed for the BFS series walk-behind floor saws and slab saws. This pre filter services an extensive range of BFS models, including the BFS 935A, BFS 1318A, BFS 1345A, and BFS 1350A families, covering both standard and long-reach configurations. As a direct OEM replacement, it ships to the exact specifications of the original part, so no guesswork is involved when ordering for your machine. Verify your model number against the fitment list to confirm compatibility before installation.
Key Features
- Genuine OEM Filtration Media: — Manufactured to Wacker Neuson's original specification, ensuring the correct particle capture rating and airflow balance for BFS engine protection.
- Drop-In Replacement: — Matches the original mounting dimensions and seating geometry of the BFS pre filter housing, allowing straightforward installation without modification.
- Broad BFS Series Coverage: — Compatible with a wide range of Wacker Neuson BFS floor saws, including the BFS 935A, BFS 1318A, BFS 1318AB, BFS 1345A, BFS 1345AB, BFS 1350A, BFS 1350AB, BFS 940A, BFS 914A, BFSX18A, and BFSX20A models.
- Engine Longevity: — A clean, intact pre filter prevents abrasive concrete dust and debris from bypassing the main air filter, protecting internal engine components from premature wear during demanding cutting work.
- Consistent Cutting Performance: — A clogged or deteriorated pre filter starves the engine of airflow, causing rough running, power loss, and increased fuel consumption — replacing it on schedule keeps the saw running at full output.
The pre filter sits upstream of the main air filter in the engine's air intake system, acting as the first line of defense against coarse dust and debris. In a floor saw environment — where concrete and aggregate dust is generated continuously — this component takes on heavy contamination loads and requires regular inspection and replacement. When the pre filter becomes clogged or torn, restricted airflow forces the engine to run rich, reducing power and accelerating wear on downstream components including the main filter element and carburetor.
