The Bomag 05550174 AC Hose Assembly WN3111 is a genuine OEM component designed for BC-series refuse/landfill compactors — including the BC 570 RB, BC 571 RB, BC 670 RB, BC 671 RB, BC 672 RB, and BC 771 RB — as well as the BW 28 RH pneumatic tyred roller. Sourced directly from Bomag, this assembly matches the original routing, connection points, and pressure ratings of the factory air conditioning circuit. If your machine's cab climate system is underperforming or showing signs of a refrigerant leak, replacing the hose assembly with a genuine OEM part is the surest path to restoring full system operation.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original pressure and temperature tolerances for the AC circuit, ensuring the hose material and fittings hold up under the thermal cycling demands of heavy compactor operation
- Direct-Fit Replacement — matches the OEM routing path and connection geometry of the original assembly, allowing the hose to seat correctly at both ends without reworking brackets or lines
- Broad BC-Series Coverage — confirmed fit across the BC 570 RB, BC 571 RB, BC 670 RB, BC 671 RB, BC 672 RB, and BC 771 RB refuse/landfill compactors, and the BW 28 RH pneumatic tyred roller
- Cab Comfort and Operator Efficiency — a properly sealed AC hose assembly maintains refrigerant charge and system pressure, keeping cab temperature controlled so operators can sustain focus during long compaction cycles
- Refrigerant Containment Compliance — an intact, OEM-spec hose prevents uncontrolled refrigerant release, supporting environmental regulations around AC system integrity on commercial equipment
The AC hose assembly carries refrigerant between components of the machine's air conditioning system — typically between the compressor, condenser, and evaporator. It must maintain a leak-free seal under both high-side pressure and the vibration stress common to landfill and compaction environments. When this hose degrades, cracks, or loses a fitting seal, refrigerant escapes, the AC system loses pressure, and cab cooling fails entirely. Replacing a worn or damaged hose assembly with a genuine Bomag part restores the closed-loop refrigerant circuit and returns the climate system to full working condition.
