The Wacker Neuson Air Filter is a genuine OEM air filter designed for the MDP3, MDP3X 75mm/3in Diaphragm Trash Pump, and PT3c series pumps. As a factory-sourced component, this filter meets the exact specification Wacker Neuson engineers built into the original machine, ensuring a direct, no-fuss swap. Whether you are servicing a single pump or maintaining a fleet, part number is the correct replacement to keep your equipment performing as intended. Confirm your model number against the fitment list below before ordering to ensure compatibility.
Key Features
- Genuine OEM Filtration Media — Sourced directly from Wacker Neuson, this air filter uses the same filtration grade as the original, protecting the engine from dust and debris ingestion at the correct capture rating.
- Drop-In Replacement — Engineered to match the original housing dimensions and seating profile of the MDP3, MDP3X, and PT3c, so it seats correctly and seals fully without trimming or adapting.
- Covers Key Pump Models — Fits the MDP3 (CE), MDP3X 75mm/3in Diaphragm Trash Pump, and PT3c series, making this a practical single-part solution across several Wacker Neuson pump lines.
- Protects Engine Air Intake — A clean, correctly fitted air filter maintains the proper air-to-fuel ratio for the engine, sustaining power output and fuel efficiency throughout the pump's duty cycle.
- Fuel System Safety — A degraded or improperly fitted air filter allows contaminants into the carburetor and combustion chamber, which can cause misfires, rich running, or internal wear — using the correct OEM part eliminates that risk.
The air filter sits at the intake of the engine and is responsible for stripping airborne dust, grit, and debris from the combustion air supply before it enters the carburetor. On job sites where pumps are running in dirty, wet, or dusty conditions, the filter takes a heavy load and degrades faster than many other service items. A clogged or damaged air filter restricts airflow to the engine, causing hard starting, loss of power, increased fuel consumption, and accelerated wear on internal components — replacing it on schedule with a genuine part like the Wacker Neuson 5000409396 is one of the most cost-effective ways to protect the engine long-term.
