Multiquip M3453300503 Right Front Duct

The Multiquip M3453300503 Right Front Duct is a genuine OEM component designed for DCA-series ultra-silent diesel generators, including the DCA125SSJU, DCA125SSJU2, DCA100SSJU, DCA125SSJU-GEER, and DCA125SSJU2-FEMA. As a direct Multiquip OEM part, M3453300503 is manufactured to the exact same specification as the original, ensuring a correct fit within the generator enclosure's airflow system. This duct is stocked and sold by DHS Equipment, your authorized source for genuine Multiquip replacement parts.

Key Features

• Genuine OEM Construction — Formed to the precise geometry of the original duct, maintaining correct airflow channeling through the front section of the generator enclosure.
• Exact Enclosure Fit — Mounts directly into the right front duct position with original mounting points, requiring no trimming or modification to the enclosure panels.
• Confirmed Fitment — Compatible with DCA125SSJU, DCA125SSJU2, DCA100SSJU, DCA125SSJU-GEER, and DCA125SSJU2-FEMA ultra-silent generator models.
• Sustained Cooling Efficiency — Properly directs intake and exhaust air within the enclosure, preventing heat buildup that can lead to derating or unplanned shutdowns on the jobsite.
• Enclosure Integrity — Restores the acoustic and thermal management performance of the ultra-silent enclosure design, keeping sound and heat levels within expected operating parameters.

The right front duct is a formed airflow component mounted inside the generator's sound-attenuating enclosure. It channels cooling air to and from the engine and alternator, helping regulate operating temperatures during continuous or heavy-load operation. When this duct is damaged, missing, or incorrectly fitted, airflow through the enclosure becomes disrupted — leading to elevated internal temperatures, reduced output capacity, and potential thermal shutdown of the generator.
