The Bomag 05581058 Ventilator is a genuine OEM component designed for BW 145 and BW 177 series single drum rollers and the BW 11 RH-5 pneumatic tyred roller. Sourced directly from Bomag, this ventilator carries the exact specifications required for proper airflow and cooling system performance across its full range of compatible machines. Confirmed fitment covers models including the BW 145 D-5, BW 145 DH-5, BW 145 PDH-5, BW 145 D-5 PL, BW 177 D-5, BW 177 DH-5, BW 177 PDH-5, BW 177-5, BW 177BVC-5, BW 177 D-5 PL, BW 177 DH-5 PL, BW 177 PDH-5 PL, and BW 11 RH-5. Using an authentic Bomag replacement ensures the cooling circuit operates within design parameters and protects downstream engine components.
Key Features
- Genuine OEM Airflow Accuracy — manufactured to Bomag's exact blade geometry and rotational spec, so cooling output matches what the engine management system expects from this ventilator
- Direct Drop-In Installation — matches original mounting dimensions and shaft interface, allowing straightforward installation without adapters or reworking of surrounding hardware
- Broad Model Coverage — fits BW 145 and BW 177 series single drum rollers across D-5, DH-5, PDH-5, and PL variants, as well as the BW 11 RH-5 pneumatic tyred roller
- Engine Temperature Protection — a properly functioning ventilator maintains consistent airflow through the cooling system, preventing thermal buildup that can cause engine derating or unplanned shutdowns during heavy compaction work
- Verified Part Number Integrity — ordering by Bomag part number 05581058 confirms you receive the correct unit for your specific machine variant, eliminating guesswork at the parts counter
The ventilator is a driven fan component responsible for moving air across the engine's cooling system — typically through the radiator or cooling fins — to dissipate heat generated during operation. On heavy compaction equipment like single drum and pneumatic tyred rollers, the engine works under sustained load, making consistent airflow critical to maintaining safe operating temperatures. When a ventilator wears, cracks, or loses blade integrity, airflow drops and the engine can overheat, leading to power loss, automatic shutdown, or long-term internal damage if left unaddressed.
