The Bomag 05821440 Dry Air Filter is a genuine OEM component designed for Bomag BW-series tandem rollers, including the BW 161, BW 190, BW 202, BW 203, and BW 205 AD 4 across multiple generation variants. As a direct OEM replacement, this filter matches the original specification for correct housing fitment and filtration performance — no adaptation needed. It is verified against Bomag's own parts catalog, giving you confidence that part number 05821440 is the right filter for your machine before it ever arrives on site.
Key Features
- OEM Filtration Media — Genuine Bomag construction ensures the filter media density and element geometry match the original, maintaining correct airflow volume and particulate capture for your tandem roller's engine.
- Direct Housing Match — This dry air filter seats into the OEM air filter housing without modification, preserving the factory sealing surface and preventing unfiltered air bypass.
- Broad Generation Coverage — Fits an extensive range of BW 161, BW 190, BW 202, BW 203, and BW 205 AD 4 tandem rollers across -4, -5, -50, AC, AD, ADH, ADO, and AM variants, including EU-Flex and CHINA-market configurations.
- Engine Protection at Every Service Interval — A correctly functioning dry air filter prevents abrasive dust and debris from reaching the engine intake, protecting cylinder walls, pistons, and valve seats from accelerated wear.
- Fuel Efficiency and Power Output — A clogged or failed air filter restricts the air-fuel mixture, causing the engine to run rich, lose power, and consume more fuel — replacing this filter on schedule keeps combustion efficiency where it should be.
The dry air filter is the primary barrier between the engine's intake system and airborne contaminants generated on asphalt paving sites — fine aggregate dust, exhaust particulates, and road debris. By capturing these particles before they enter the combustion chamber, the filter protects critical engine components and maintains the correct air-to-fuel ratio for consistent power output. When this filter becomes saturated or damaged, intake restriction climbs, engine temperatures rise, and internal wear accelerates — making timely replacement one of the most cost-effective engine maintenance steps an operator can perform.
