The Bomag 05581051 Ventilator is a genuine OEM component designed for Bomag BW-series tandem rollers and BM-series cold milling machines. Sourced directly from Bomag, this ventilator carries the same specifications as the part installed at the factory, ensuring a correct, drop-in fit across every compatible machine. It is confirmed to fit the BW 80 AD-5, BW 90 AD-5, BW 90 AC-5, BW 90 SC-5, BW 90 SL-5, BW 90 SL-5 CC, BW 100 ADM-5, BW 100 ACM-5, BW 100 SC-5, BW 100 SCC-5, BW 100 SLM-5 tandem rollers, as well as the BM2000/65 Stage V and BM2200/65 Stage V cold milling machines. When airflow and cooling are critical to keeping your equipment running at full capacity, using the correct OEM-specified ventilator is the only way to maintain performance and protect the drivetrain and engine systems it supports.
Key Features
- Genuine OEM Airflow Integrity — built to Bomag's exact blade pitch, diameter, and material spec, delivering the correct volume and velocity of airflow the cooling system depends on
- Direct Replacement Fit — matches the original mounting configuration and shaft interface, installing straight onto compatible machines without alteration
- Broad Confirmed Fitment — verified for the BW 80 AD-5, BW 90 AD-5, BW 90 AC-5, BW 90 SC-5, BW 90 SL-5, BW 90 SL-5 CC, BW 100 ADM-5, BW 100 ACM-5, BW 100 SC-5, BW 100 SCC-5, BW 100 SLM-5 tandem rollers, and the BM2000/65 Stage V and BM2200/65 Stage V cold milling machines
- Thermal Protection for Engine and Drivetrain — a worn or damaged ventilator reduces airflow, leading to elevated operating temperatures, premature component wear, and unplanned shutdowns on the jobsite
- Authentic Bomag Part Number 05581051 — order with confidence knowing the part number matches the Bomag OEM catalog exactly, eliminating the risk of receiving a mismatched component
The ventilator is responsible for moving air across the engine's cooling system, pulling heat away from critical components such as the radiator, hydraulic oil cooler, and charge air cooler. On tandem rollers and cold milling machines operating under sustained load, consistent and adequate airflow is essential to prevent overheating and protect the engine and hydraulic circuits. When the ventilator wears, cracks, or loses blade efficiency, cooling capacity drops — leading to thermal shutdowns, accelerated wear on surrounding components, and costly repairs that far exceed the cost of a timely replacement.
