The Wacker Neuson Air Cleaner is a genuine OEM air cleaner designed for ML440 Light Towers and MG5 Portable Generators, including MG5, MG5d, and MG5sd series machines. As a direct Wacker Neuson OEM part, the is manufactured to the same specification as the original component, ensuring a direct, hassle-free installation. This air cleaner is compatible across a broad range of ML440 and MG5 series configurations, making it a dependable service part to keep on hand for scheduled maintenance or field replacement.
Key Features
- OEM Filtration Integrity — Built to Wacker Neuson's original filtration specification, delivering the same particulate capture efficiency as the factory-installed unit to protect engine internals from dust and debris.
- Drop-In Installation — Matches the original mounting configuration on ML440 and MG5 series machines, fitting directly into the existing air cleaner housing without adapters or modifications to the airflow path.
- Broad Series Compatibility — Fits ML440 Light Towers, ML440 Multifunction Floodlight Towers, and MG5, MG5d, and MG5sd Portable Generators across multiple build configurations.
- Engine Protection at Every Hour — A clean, correctly seated air cleaner maintains the proper air-to-fuel ratio and prevents abrasive particles from entering the combustion chamber — a worn or clogged unit accelerates cylinder and piston wear.
- Fuel System Compliance — Maintaining a properly functioning air cleaner is critical to keeping fuel combustion clean and efficient; a degraded unit can cause rich running conditions, increased fuel consumption, and carbon buildup.
The air cleaner filters incoming combustion air before it reaches the engine, removing dust, dirt, and airborne particles that would otherwise wear down internal engine components. On generator and light tower applications operating in outdoor or construction environments, clean filtration is especially critical — contaminated air accelerates cylinder wear and can lead to loss of compression over time. When the air cleaner becomes clogged or damaged, the engine is forced to run with restricted airflow or unfiltered air, resulting in poor performance, increased fuel use, and potential long-term engine damage.
