The Wacker Neuson External Air Filter is a genuine OEM component designed for the BFS735 gasoline-powered floor saw series and the WP1540A and WP1550A single-direction vibratory plate compactors. As a factory-sourced part, it meets the exact fit and material specifications required for these machines, ensuring the engine receives properly filtered air intake with every use. This filter is confirmed to fit multiple BFS735 and WP1550Aw configurations, including CN and Sunbelt variants. Keeping the correct air filter in place protects the engine and maintains consistent power output across demanding compaction and cutting applications.
Key Features
- Genuine OEM Filtration Media — Manufactured to Wacker Neuson's specified porosity and filtration efficiency for these engine configurations, not a generic approximation.
- Direct Drop-In Fitment — Engineered to seat correctly in the external air filter housing on BFS735 and WP-series machines without modification to mounting tabs or housing clips.
- Wide Model Coverage — Fits the BFS735 floor saw (including CN variants), WP1540A, WP1540Aw, WP1550A, and WP1550Aw vibratory plate compactors across multiple serial number ranges.
- Engine Protection Where It Counts — A clogged or deteriorated external air filter starves the engine of clean air, causing rough running, increased fuel consumption, and premature cylinder wear — this OEM replacement restores clean airflow.
- Dual-Application Confidence — Covers two distinct equipment families — floor saws and plate compactors — making it a practical stocking part for fleets running both machine types.
The external air filter is the engine's first line of defense against dust, debris, and particulate matter — a critical concern on floor-sawing and soil-compaction sites where airborne contaminants are constant. It captures fine particles before they can enter the carburetor and combustion chamber, preventing accelerated wear on piston rings and cylinder walls. When the filter becomes clogged or damaged, the engine runs rich, loses power, and can overheat; replacing it on schedule with the correct OEM part keeps the engine breathing cleanly and performing at full rated output.
