The Bomag 78200201 Spray Bar is a genuine OEM component designed for BW 100 AD-3 and BW 100 AD-4 tandem rollers. Sourced directly from Bomag, this spray bar matches the original assembly specification for a direct, hassle-free installation. It is confirmed compatible with both the BW 100 AD-3 and BW 100 AD-4 models, making it the straightforward choice when servicing the water sprinkler system on these machines. Using part number 78200201 ensures you get the correct fitment the first time, avoiding costly rework on the jobsite.
Key Features
- Genuine OEM Water Distribution Accuracy — manufactured to Bomag's original flow and nozzle-spacing specifications, ensuring even water coverage across both drums rather than the uneven wetting that worn or ill-fitting bars cause
- Direct Replacement for BW 100 AD-3 and BW 100 AD-4 — mounts to the existing spray system brackets on both tandem roller variants without modification or adaptation
- Confirmed Tandem Roller Fitment — verified for BW 100 AD-3 and BW 100 AD-4 tandem rollers, so you can order with confidence knowing this bar is engineered specifically for these machines
- Consistent Drum Wetting for Clean Asphalt Passes — a properly functioning spray bar prevents hot mix from sticking to the drums, protecting compaction quality and surface finish on every pass
- Corrosion-Resistant Construction — built to withstand continuous water flow and outdoor exposure, resisting the internal buildup and cracking that prematurely fails lesser components
The spray bar is a core part of a tandem roller's water sprinkler system, distributing a controlled film of water across the drum surface during asphalt compaction. This water barrier keeps hot mix from adhering to the steel drum, which would otherwise degrade the mat surface and force frequent stops for cleanup. When the spray bar becomes blocked, cracked, or misaligned, water distribution becomes uneven or fails entirely — leading to drum pickup, surface tearing, and lost compaction efficiency. Replacing it promptly with a correct-specification part like the Bomag 78200201 restores full system performance and protects the quality of the finished mat.
