The Bomag 05821420 Air Filter is a genuine OEM component designed for Bomag BC-series refuse and landfill compactors, BC 473 EB-3 soil compactors, and MPH 121 and MPH 122 recyclers/stabilizers. As a direct OEM replacement, this air filter meets the exact specifications set by Bomag, ensuring proper engine protection across the full range of compatible machines. This filter fits models including the BC 570 RB, BC 571 RB, BC 670 RB, BC 671 RB, BC 671 RS, BC 672 RB, BC 771 RB, BC 771 RS, BC 972 RB, BC 972 RB-2, BC 972 RB-3, BC 972 RB-4, BC 1172 RB, BC 1172 RB-2, BC 1172 RB-3, BC 1172 RB-4, BC 473 RB-3, BC 473 EB-3, MPH 121, and MPH 122. Sourcing the correct OEM air filter for your Bomag machine is one of the most straightforward ways to protect engine longevity and maintain consistent performance under demanding compaction and stabilizing conditions.
Key Features
- OEM Filtration Integrity — Manufactured to Bomag's exact filtration specification, this air filter delivers the correct airflow restriction and particulate capture rate required by the engine on your refuse compactor, soil compactor, or recycler/stabilizer.
- Direct-Fit Replacement — Engineered to the same housing dimensions and sealing geometry as the original, this filter seats correctly in the air intake system without adaptation or modification to mounting hardware.
- Broad Compatibility Across the BC and MPH Lines — A single part number 05821420 covers a wide range of Bomag refuse and landfill compactors including the BC 670 RB, BC 771 RB, BC 972 RB, BC 1172 RB, and multiple generation variants, plus the BC 473 EB-3 soil compactor and MPH 121 and MPH 122 recyclers/stabilizers.
- Engine Protection Under Heavy-Duty Conditions — Refuse compactors and recyclers operate in environments with high concentrations of airborne dust, debris, and particulates. A correctly fitted OEM air filter keeps contaminants out of the intake, preventing accelerated cylinder and valve wear.
- Consistent Power and Fuel Efficiency — A clogged or ill-fitting air filter restricts airflow, richens the fuel mixture, and causes the engine to run rough or lose power. Replacing it with part number 05821420 restores the correct air-to-fuel ratio and smooth engine response.
The air filter is a critical engine intake component that prevents dust, dirt, and debris from entering the engine's combustion chambers. In heavy equipment like refuse compactors and recyclers/stabilizers — machines that work in some of the most contaminated environments on any jobsite — a clean, correctly fitted air filter is essential to maintaining engine health and power output. When an air filter becomes clogged or damaged, the engine is starved of clean air, leading to rough running, increased fuel consumption, and over time, serious internal engine wear.
