Key Features

• Genuine OEM Filtration Media — manufactured to Bomag's specified filtration efficiency and media density, ensuring the secondary filter performs exactly as the air intake system requires rather than approximating it
• Drop-In Replacement — matches the original housing dimensions and seal interface of the air filter assembly, allowing straightforward installation without modification to the filter canister or mounting hardware
• Broad Fitment Across Three Equipment Classes — confirmed for Bomag BF-series pavers including BF 600, BF 700, BF 800, and BF 900 models, BW-series tandem rollers including BW 141 AD-5, BW 151 AD-5, BW 161 AD-5, BW 190 AD-5, BW 191 AD-5, BW 202 AD-5, and BW 206 AD-5 variants, and BM-series cold milling machines including BM 1000/35, BM 1200/35, BM 1300/35, BM 2000/75, BM 2200/75, and BM 2500/75
• Engine Protection at the Secondary Stage — the secondary element acts as a safety barrier behind the primary filter, capturing fine particulate that bypasses the outer stage and preventing abrasive dust from reaching engine internals where it causes accelerated wear
• Preserves Air-Fuel Balance — a clogged or degraded secondary element restricts airflow, disrupting the engine's air-to-fuel ratio, which can cause rough running, increased fuel consumption, and reduced output power on demanding paving and milling passes

The secondary filter element is the inner safety filter housed within the engine's air cleaner assembly. While the primary (outer) element handles the bulk of dust and debris, the secondary element provides a final line of defense, trapping fine particles that penetrate the first stage. This is especially critical on pavers, tandem rollers, and cold milling machines that operate in high-dust environments where airborne contaminants are constant. When the secondary element becomes saturated or torn, unfiltered air enters the engine directly, accelerating cylinder and valve wear and shortening engine service life significantly.
