Key Features
- Genuine OEM Air Filtration Integrity — manufactured to Bomag's original specification, this prefilter delivers the correct particle-capture efficiency to protect the engine air intake system from dust and debris in demanding compaction environments.
- Direct Drop-In Replacement — engineered to match the original mounting configuration, this prefilter installs into the existing housing without modification, restoring the factory air filtration setup.
- Broad Single Drum Roller Coverage — fits an extensive range of Bomag single drum rollers including the BW 213 D-3, BW 216 DH-3, BW 219 DH-3, BW 177 PDH-3, BW 212 D-3, BW 225 D-3, BW 211 PD-3, BW 214 DH-3, and related variants.
- Engine Protection at the First Line of Defense — a functioning prefilter intercepts coarse contaminants before they reach the primary air filter element, extending primary filter service life and reducing the risk of abrasive particles entering the engine.
- OEM Part Number Confidence — ordering by part number 05821101 ensures exact cross-reference to Bomag's own catalog, eliminating the guesswork of sourcing the correct filter for your specific roller variant.
The prefilter is the outermost stage of the engine air filtration system, positioned upstream of the primary air filter element. Its role is to capture larger airborne particles — sand, grit, and coarse dust — before they can load and prematurely clog the main filter. On heavy compaction equipment like Bomag single drum rollers, which operate in consistently high-dust environments, a functioning prefilter is critical to maintaining airflow and engine efficiency. When the prefilter becomes blocked or deteriorates, the primary filter element faces an increased contamination load, shortening its service interval and potentially allowing fine abrasive particles to reach the engine if the primary element is also compromised.
