The Bomag 05821325 Air Filter Housing is a genuine OEM component designed for a wide range of Bomag single drum rollers, tandem rollers, and walk-behind rollers, including BW 124 DH-3, BW 131 AD-5, BW 115 AC-5, BW 100 AD-4, BW 120 AD-4, BW 125 AD-4, BW 6, and C 815 C models. As a direct-from-Bomag part, this housing is manufactured to the same specification as the original, ensuring a correct fit with no guesswork. Sourcing a genuine OEM replacement means you can trust that the housing will mate precisely with your engine's intake system, preserving the filtration performance the machine was designed around.
Key Features
- Genuine OEM Construction — manufactured by Bomag to original production tolerances, ensuring the housing seals and mounts exactly as the factory-built unit did
- Direct Drop-In Replacement — matches the mounting points, inlet geometry, and filter-seating surfaces of the original housing across all covered Bomag roller variants
- Broad Roller Coverage — fits BW 124, BW 115, BW 120, BW 125, BW 131, and BW 100 series tandem and single drum rollers, C 815 C single drum rollers, and BW 6 walk-behind rollers, including generation -2, -3, -4, -5, and -40 variants
- Intake Integrity Preserved — a correctly seated housing prevents unfiltered air from bypassing the filter element, protecting the engine from abrasive dust and debris common on compaction jobsites
- Verified Part Number — order confidently using Bomag part number 05821325, cross-referenced to the specific models listed to eliminate compatibility errors
The air filter housing is the structural enclosure that holds the engine air filter element in place and channels incoming air through the filtration media before it enters the engine. It forms a sealed path between the ambient air intake and the engine's intake manifold, and its integrity is critical — a cracked, warped, or improperly seated housing allows unfiltered air to reach the engine, accelerating wear on cylinder bores, pistons, and rings. On compaction equipment operating in dusty site conditions, a damaged housing can significantly shorten engine service life, making timely replacement with a properly fitted unit essential to keeping the powertrain running at full capacity.
