The Bomag 05821028 Oil Bath Air Filter is a genuine OEM component designed for the BW 120 AD tandem roller. Sourced directly from Bomag, this filter meets the original engineering specifications for the BW 120 AD, ensuring proper engine air filtration without guesswork on fitment. As a genuine OEM part, it carries the same quality and dimensional accuracy as the filter installed at the factory, making it the straightforward choice for scheduled maintenance or filter replacement on your machine.
Key Features
- OEM Filtration Integrity — built to Bomag's original media density and oil reservoir specifications, delivering the same engine protection as the factory-installed unit on BW 120 AD tandem rollers
- Direct-Fit Replacement — engineered to the exact housing dimensions and mounting configuration of the BW 120 AD, so installation goes smoothly without adapting or trimming
- Confirmed Fitment — verified for the Bomag BW 120 AD tandem roller; reference part number 05821028 when ordering to confirm compatibility with your machine
- Engine Protection at Full Output — a properly functioning oil bath air filter captures abrasive dust and debris before they reach the engine, helping the machine maintain full power and efficient fuel combustion on compaction passes
- Fuel System Safety — a clogged or degraded air filter causes rich-running conditions and accelerated engine wear; replacing with a genuine Bomag filter restores the correct air-to-fuel ratio and protects internal engine components
An oil bath air filter cleans incoming combustion air by drawing it through a reservoir of oil, which traps dust, grit, and fine particles before they can enter the engine. This style of filter is well suited to demanding outdoor compaction work where airborne contaminants are heavy. When the oil becomes saturated or the filter element degrades, filtration efficiency drops sharply — allowing abrasive particles to reach cylinder walls and accelerate engine wear. Replacing the filter on schedule with the correct Bomag part keeps the engine breathing cleanly and performing at its rated output.
