Key Features
- Genuine OEM Construction — Manufactured to the exact material and dimensional specifications of the original duct, ensuring correct airflow routing through the enclosure without gaps or misalignment.
- Direct-Fit Replacement — Engineered to mount to the rear cover assembly of compatible DCA-series generators exactly as the original, using existing hardware and attachment points.
- Broad DCA-Series Compatibility — Fits DCA125SSJU, DCA125SSJU2, DCA125SSJU-GEER, DCA125SSJU2-FEMA, and DCA100SSJU ultra-silent generator models.
- Thermal Management Integrity — Properly channels cooling air through the generator enclosure, protecting engine and alternator components from heat buildup during sustained operation.
- Enclosure Sealing Performance — Restores the sound-attenuating enclosure to its designed configuration, maintaining the noise-reduction performance these ultra-silent units are built to deliver.
The rear cover duct is an internal airflow management component within the generator's sound-attenuating enclosure. It directs cooling air across the engine and alternator in a controlled path, preventing heat from accumulating in critical areas during extended run cycles. When the duct is cracked, displaced, or missing, cooling efficiency drops and the generator may run hotter than intended — shortening service life and potentially affecting power output stability. Replacing a damaged duct with a correct OEM part like the M3443300303 restores proper thermal performance and keeps the enclosure functioning as a complete system.
