Key Features
- Genuine OEM Airflow Integrity — manufactured to Bomag's original design specs, ensuring the ventilator moves the correct volume of air to protect engine and drivetrain components from heat buildup
- Direct Drop-In Replacement — engineered to match the original mounting points, blade geometry, and drive interface for a straightforward swap on compatible tandem rollers
- Broad Tandem Roller Coverage — fits BW 174 AP-4, BW 174 AP-4i, BW 141 AD-5, BW 151 AD-5, BW 151 AC-5, BW 154 AD-5, and additional variants across the BW 141, BW 151, and BW 174 families
- Sustained Cooling Performance — a properly functioning ventilator keeps operating temperatures in check during continuous compaction passes, helping the machine run at full efficiency under load
- Verified Part Number Traceability — order with confidence knowing part number 05581036 is the Bomag-specified ventilator for these tandem roller models, eliminating guesswork at the parts counter
The ventilator is responsible for drawing or forcing air across the engine's cooling system, preventing thermal overload during operation. On ride-on tandem rollers like the BW 174 and BW 151 series, which work continuously on asphalt paving projects, consistent airflow is critical — without it, engine temperatures climb rapidly, leading to power loss, accelerated wear, or shutdown. When the ventilator blades crack, become unbalanced, or the unit fails outright, cooling efficiency drops immediately, putting the engine and surrounding components at risk. Replacing a worn ventilator with the correct OEM unit restores proper airflow and protects the machine's long-term reliability.
