The Wacker Neuson Prefilter Element is a genuine OEM component designed for a wide range of Wacker Neuson walk-behind concrete trowels, trash pumps, and select compaction and screed equipment. As a direct OEM replacement, the is manufactured to the same specifications as the original part, ensuring proper fitment and performance across all compatible machines. This prefilter element fits the CT36 and CT48 walk-behind trowel series — including AGP, ADP, AGT, ADT, AVP, and AVT variants — as well as PT3A centrifugal trash pumps and select BPU reversible vibratory plates, BPS single-direction vibratory plates, and HPG screed power units.
Key Features
- OEM Filtration Media: — Engineered to the same porosity and particle-capture spec as the original, keeping contaminants out of the carburetor and engine intake on every compatible machine.
- Drop-In Replacement: — Sized and shaped to seat correctly in the factory air filter housing on CT36, CT48, and PT3A equipment without modification to the housing or retaining clips.
- Broad Compatibility: — A single part number covers CT36 and CT48 walk-behind trowel variants, PT3A 3-inch trash pumps, select BPU and BPS vibratory plates, HPG screed power units, and more.
- Protects Engine Performance: — A clean prefilter ensures the engine breathes properly; a clogged or degraded element restricts airflow, causing rich-running conditions, power loss, and accelerated engine wear.
- Genuine Wacker Neuson Part: — Supplied as an authorized OEM component, so you can trust the part number, materials, and dimensional accuracy without second-guessing compatibility.
A prefilter element is the first line of defense in the air filtration system, sitting upstream of the main air filter to capture larger particles — dust, debris, and moisture — before they can reach the primary filter element or engine intake. By blocking coarse contaminants early, the prefilter extends the service life of the main filter and helps maintain consistent airflow to the carburetor. When the prefilter becomes saturated or torn, airflow is restricted or unfiltered air bypasses the system entirely, leading to carburetor fouling, rough running, excessive fuel consumption, and long-term cylinder wear. Regular inspection and timely replacement of the prefilter element is one of the simplest and most cost-effective ways to protect engine longevity on trowels, pumps, and other small-engine equipment.
