Key Features
- OEM Filtration Integrity — manufactured to Bomag's original filtration specification, delivering the correct media density and particle capture rating for these tandem roller engines
- Direct Drop-In Replacement — engineered to match the original housing dimensions and sealing surfaces, installing into the airbox without adaptation
- Broad Tandem Roller Coverage — fits BW 100, BW 120, BW 125, BW 135, and BW 138 series tandem rollers across AC and AD drive variants, including the BW 138 AD, BW 120 AD-3, and BW 125 ADH
- Engine Protection Where It Counts — a correctly functioning air filter blocks abrasive dust and debris before they reach the engine; a clogged or failed filter leads to accelerated cylinder wear and loss of power under load
- Scheduled Maintenance Made Simple — stocking part number 05821084 means planned filter changes stay on schedule, keeping these tandem rollers productive through demanding paving and compaction work
The air filter is the engine's first line of defense against airborne contaminants — dust, debris, and fine particles that are drawn in with every intake stroke. By trapping these particles before they enter the combustion chamber, the filter protects cylinder walls, piston rings, and valves from abrasive wear. On tandem rollers operating in dusty asphalt and compaction environments, a clean, properly sealing air filter is essential to maintaining engine efficiency and service life. When the filter becomes saturated or damaged, airflow restriction causes the engine to run rich, lose power, and consume more fuel — making timely replacement a core part of any preventive maintenance routine.
