The Bomag 05576251 Ventilator is a genuine OEM component designed for BW 900 AD tandem rollers and BW 900-2 walk-behind rollers. Sourced directly from Bomag, this ventilator matches the original part in every critical dimension, ensuring a drop-in installation without rework or adaptation. This component is confirmed compatible with the BW 900 AD and BW 900-2, making it a dependable choice when restoring proper airflow and cooling function to your machine.
Key Features
- Genuine OEM Airflow Performance — manufactured by Bomag to the exact blade geometry and rotational spec of the original, so cooling output is fully restored from day one
- Direct-Fit Replacement — matches the original mounting interface on the BW 900 AD and BW 900-2, allowing straightforward installation against the existing housing and drive
- Confirmed Fitment — verified for BW 900 AD tandem rollers and BW 900-2 walk-behind rollers using Bomag part number 05576251
- Sustained Engine Temperature Control — a correctly functioning ventilator keeps airflow consistent across the cooling system; a worn or failed unit leads to overheating and unplanned stoppages
- OEM Part Assurance — as a genuine Bomag part, this ventilator carries the same material grade and balance specification as the unit installed at the factory, avoiding the premature wear that can come from imprecise replacements
The ventilator is the rotating fan component responsible for drawing or pushing air through the machine's cooling system. By maintaining steady airflow across the engine and associated heat exchangers, it prevents thermal buildup that can damage internal components and shorten engine life. When a ventilator cracks, becomes unbalanced, or loses blade integrity, cooling efficiency drops rapidly — often showing up first as rising temperature gauge readings or intermittent thermal shutdowns during heavy compaction work.
