The Bomag 05594393 AC Hose Assembly WN3111 is a genuine OEM component designed for BW 900 AD tandem rollers and BW 900-2 walk-behind rollers. Sourced directly from Bomag, this assembly matches the original routing, fittings, and pressure ratings of the factory air conditioning circuit — so installation is straightforward and the system performs as intended. Whether you are servicing a BW 900 AD or a BW 900-2, part number 05594393 is the correct OEM-specified hose for restoring your AC system to full operation.
Key Features
- OEM-Rated Pressure Integrity — Built to the same hose specification and burst-pressure tolerance as the original, ensuring the AC circuit holds charge without seepage or premature failure.
- Exact Routing and Fitting Match — This assembly replicates the factory hose path and end-fitting geometry, allowing it to connect directly to existing AC system ports without rework or adapter fittings.
- Confirmed Fitment — Engineered for Bomag BW 900 AD tandem rollers and BW 900-2 walk-behind rollers; consult your machine's serial number when ordering to confirm the correct application.
- Restored Operator Comfort — A failed or leaking AC hose causes refrigerant loss and total cooling failure in the cab; this replacement restores the climate control performance operators depend on during long compaction shifts.
- Genuine Bomag Quality — As a genuine OEM part, the AC Hose Assembly WN3111 meets Bomag's own materials and construction standards for hose construction, ensuring long service life in a high-vibration compaction environment.
The AC Hose Assembly WN3111 is a pressurized refrigerant line that carries conditioned refrigerant between major components of the machine's air conditioning system — typically between the compressor, condenser, and evaporator. It must maintain a sealed, flexible connection while withstanding the vibration and heat cycles generated by both the engine bay and the surrounding work environment. When an AC hose cracks, swells, or develops a leak at its fittings, refrigerant escapes, the system loses pressure, and cab cooling stops — leaving operators exposed to heat stress and reducing sustained productivity on the jobsite.
