The Wacker Neuson Air Filter Precleaner is a genuine OEM component designed for the RD11A and RD11AEC hydrostatic double drum vibratory rollers and the CRT36ASO, CRT36ASN, and CRT46ASO ride-on concrete trowels. As a direct OEM replacement sourced from Wacker Neuson, part is manufactured to the same specifications as the original, ensuring a correct fit with no guesswork on installation. This precleaner works in tandem with the primary air filter to intercept large dust, debris, and airborne particles before they reach the main filtration stage. Keeping this component in good condition is one of the simplest ways to protect engine health and extend service intervals on your machine.
Key Features
- Genuine OEM Filtration Media: — Manufactured to Wacker Neuson's original material and porosity specifications, delivering consistent particle separation across the full operating range of both roller and trowel applications.
- Direct-Fit Replacement: — Engineered to seat correctly in the existing air filter housing, with no trimming or adapter hardware needed for installation on compatible models.
- Broad Model Coverage: — Fits the RD11A and RD11AEC hydrostatic tandem rollers as well as the CRT36ASO, CRT36ASN, and CRT46ASO ride-on concrete trowels, covering two distinct Wacker Neuson equipment families under a single part number.
- Engine Protection at the First Stage: — Captures coarse dust and debris before it reaches the primary air filter, extending the service life of the main filter element and reducing the frequency of full filter changes.
- Fuel Efficiency and Power: — A clean, unobstructed precleaner maintains proper air-to-fuel mixture, helping the engine run at rated power output and avoid the fuel consumption increase associated with restricted airflow.
The air filter precleaner is the first line of defense in a two-stage air intake system. It sits upstream of the primary air filter element and uses centrifugal action or a coarse filter medium to knock out large particles — dirt, dust, and debris — before they can load up and clog the main filter. On machines operating in heavy concrete finishing environments or on compaction sites with significant airborne dust, this stage takes on a disproportionate share of the contamination load. When the precleaner becomes saturated or damaged, the primary filter clogs prematurely, airflow drops, the engine loses power, and fuel consumption rises. In severe cases, unfiltered abrasive particles bypass both stages and accelerate internal engine wear.
