The Multiquip M3423200704 is a genuine OEM Duct Cover designed for DCA-series ultra-silent diesel generators including the DCA70USI, DCA85USJ, DCA125USI, DCA125USJ, DCA150USJ, and related CAN variants. As a direct factory replacement, this part matches the original specification and installs without modification. Sourced from Multiquip, the M3423200704 ensures your generator's ventilation and acoustic enclosure system performs exactly as intended across all compatible DCA ultra-silent models.
Key Features
- Genuine OEM Enclosure Integrity — Manufactured to original tolerances, this duct cover maintains the precise airflow channel geometry required for proper generator cooling and sound attenuation.
- Direct-Fit Replacement — Engineered to match the original mounting points and panel profiles of the DCA ultra-silent series, allowing straightforward swap-out during service.
- Broad DCA Series Compatibility — Fits DCA70USI, DCA85USJ, DCA85USJ2, DCA125USI, DCA125USJ, DCA125USI3CAN, DCA150USJ, DCA150USJ2, DCA150USJ3CAN, DCA150USJ3CAN (FR), and DCA-70USJ models.
- Thermal Management Protection — A correctly seated duct cover directs cooling airflow through the generator set as designed; a missing or damaged cover disrupts airflow, leading to elevated operating temperatures.
- Acoustic Enclosure Compliance — On ultra-silent generators, enclosure panel components like this duct cover contribute directly to noise suppression; using the correct OEM part preserves the unit's rated sound level performance.
The duct cover is a structural panel component within the acoustic enclosure of DCA ultra-silent generator sets. It channels ventilation airflow across the engine and alternator while also forming part of the sound-dampening shell that gives the ultra-silent series its low noise output. When this cover is cracked, missing, or improperly fitted, cooling airflow becomes uncontrolled and noise levels rise, both of which can affect runtime performance and compliance with site noise requirements. Replacing a damaged duct cover with a genuine OEM part restores the generator's thermal and acoustic performance to specification.
