The Multiquip 5112800111 Water Duct Cover is a genuine OEM component designed for DCA40SSAI, DCA40SSI, DCA45SSIU2, DCA45SSIU2-FEMA, and DCA45SSIU2-GEER ultra-silent diesel generators. As a direct factory replacement, this cover ensures the cooling air and water duct pathway remains properly sealed and aligned within the generator enclosure. Sourced from Multiquip, part number 5112800111 matches the original in material, dimensions, and fit — so installation goes in without guesswork or modification.
Key Features
- Genuine OEM Construction: — Manufactured to Multiquip's original material and dimensional specifications, ensuring the cover seats and seals correctly within the duct assembly.
- Direct-Fit Replacement: — Engineered to drop into the same mounting position as the original, with no trimming or adapter hardware needed.
- Confirmed Fitment: — Compatible with DCA40SSAI, DCA40SSI, DCA45SSIU2, DCA45SSIU2-FEMA, and DCA45SSIU2-GEER ultra-silent generator models.
- Cooling System Integrity: — A properly fitted water duct cover maintains directed airflow through the cooling system, preventing heat buildup that can force the generator into thermal shutdown during operation.
- Enclosure Compliance: — Correct duct coverage is essential for maintaining the noise-attenuating and weather-sealing properties of the ultra-silent enclosure design.
The water duct cover is part of the internal airflow management system within Multiquip's ultra-silent generator enclosures. It channels and contains the flow of cooling air across the engine and alternator components, preventing hot air recirculation and protecting internal systems from debris ingress. When this cover is cracked, missing, or improperly seated, cooling efficiency drops and the generator's thermal protection systems may trigger premature shutdowns — making timely replacement critical to sustained runtime and output stability.
