The Multiquip M3443002103 Duct is a genuine OEM component designed for DCA125USI3CAN, DCA125USI, and DCA85USJ2 ultra-silent diesel powered generators. Sourced directly from Multiquip, this part meets the exact specifications of the original duct installed at the factory. It is a direct-fit replacement for the DCA series, ensuring the airflow path within the generator enclosure performs exactly as intended. Verify your model code against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Construction — Manufactured to the original dimensional and material specifications, ensuring the duct maintains the correct airflow geometry inside the generator enclosure.
- Direct-Fit Replacement — Designed to drop into the existing mounting position on DCA125USI3CAN, DCA125USI, and DCA85USJ2 units without reworking surrounding components.
- Confirmed DCA Series Fitment — Compatible with DCA125USI3CAN, DCA125USI, and DCA85USJ2 ultra-silent diesel generator models.
- Supports Proper Cooling Airflow — A correctly fitted duct channels cooling air efficiently through the enclosure; a cracked, warped, or missing duct allows heat buildup that can shorten component life and trigger thermal shutdowns.
- Genuine Part Number Assurance — Ordering by Multiquip part number M3443002103 ensures you receive the correct duct for your specific generator model, avoiding costly mis-fits.
The duct in a generator enclosure serves as a defined channel that directs cooling airflow over heat-producing components — including the engine, alternator, and control systems — and exhausts it safely out of the cabinet. In ultra-silent generators like the DCA series, the enclosure is intentionally sealed to suppress noise, which makes managed airflow critical; without a properly sealed and intact duct, hot air can recirculate inside the cabinet rather than being expelled. A damaged or missing duct leads to elevated operating temperatures, reduced output efficiency, and potential thermal protection trips that take the generator offline.
