The Multiquip 50314200 Cooling Air Duct RW-1404 is a genuine OEM cooling air duct designed for the RW1404, RW1404MR, and RW1504HF walk-behind rollers. As a direct OEM replacement sourced from Multiquip, this duct carries the same fit and form as the original component installed at the factory. Verified fitment covers the RW1404MR (S/N 326075 and up) and RW1504HF (up to S/N ), so confirm your serial number range before ordering to ensure compatibility. DHS Equipment supplies this part as an authorized Multiquip dealer, giving you confidence that 50314200 is the correct part for your machine.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional specifications as the original duct, ensuring correct airflow channeling over the engine cooling system.
- Direct Drop-In Replacement — Mounts to the same attachment points as the factory duct, requiring no trimming or modification to fit the RW1404 roller chassis.
- Confirmed Fitment for RAMMAX Roller Models — Compatible with RW1404, RW1404MR (S/N 326075 and up), and RW1504HF (up to S/N 1534188) walk-behind rollers.
- Sustained Engine Cooling Efficiency — Correctly routes cooling air across the engine, helping maintain operating temperatures and preventing heat-related power loss during continuous compaction runs.
- Engine Protection Against Overheating — A cracked or missing air duct allows cooling air to escape the intended path, raising engine temperatures and risking premature wear or shutdown on the job.
The cooling air duct channels airflow generated by the engine's recoil or blower system directly across the cylinder and cooling fins of the roller's engine. By confining and directing this airflow, the duct ensures the engine sheds heat efficiently during operation. When the duct is cracked, warped, or missing entirely, cooling air disperses before reaching the engine's hottest surfaces — leading to elevated operating temperatures, reduced engine output, and potential thermal shutdown during demanding compaction work.
