The Bomag 05821086 Air Filter Element is a genuine OEM component designed for Bomag BW 100, BW 120, BW 125, BW 135, and BW 138 series tandem rollers. As a direct OEM replacement, this air filter element meets Bomag's original engineering specifications, ensuring a correct, hassle-free installation on compatible machines. Sourced directly from Bomag, this component is the same part installed at the factory, giving operators confidence that engine air intake protection is fully restored to original standards.
Key Features
- OEM Filtration Media — Genuine Bomag construction ensures the filter media matches the original pore structure and capacity, delivering consistent particulate capture for tandem roller engines operating in dusty compaction environments.
- Direct Drop-In Replacement — Engineered to the exact dimensions and sealing geometry of the original, this air filter element installs directly into the factory airbox housing without modification.
- Broad Tandem Roller Coverage — Fits a wide range of Bomag tandem rollers including BW 100 AC-3, BW 100 AD-3, BW 120 AC-3, BW 120 AD-3, BW 125 ACH, BW 125 ADH, BW 135 AC, BW 135 AD, BW 138 AC, and BW 138 AD models.
- Engine Protection at Every Service Interval — A correctly functioning air filter element prevents abrasive dust and debris from entering the engine, protecting cylinders, pistons, and valves from premature wear during asphalt compaction work.
- Fuel Efficiency Maintained — A clogged or deteriorated filter element restricts airflow and disrupts the air-fuel ratio, leading to increased fuel consumption and reduced engine output; timely replacement with part number 05821086 keeps combustion efficient.
The air filter element sits in the engine's intake system and acts as the first line of defense against airborne contaminants — dust, grit, and fine debris common on paving and compaction sites. By trapping these particles before they reach the combustion chamber, the filter protects internal engine components from abrasive damage and helps the engine maintain a clean, efficient air-fuel mixture. When the element becomes saturated or damaged, airflow is restricted, engine performance drops, and long-term internal wear accelerates — making regular inspection and replacement a critical part of routine maintenance on any Bomag tandem roller.
