The Multiquip M3443300503 Rear Cover Duct is a genuine OEM component designed for the DCA150SSJU, DCA150SSJU2, DCA150SSVU, and DCA150SSVU-FEMA ultra-silent diesel generator series. As a direct OEM replacement, it is manufactured to the same standards as the original part, ensuring a correct installation with no guesswork on fit or function. This part is sourced directly from Multiquip, so you can order with confidence knowing you are getting the exact component specified for these machines.
Key Features
- Genuine OEM Construction — Manufactured to original design tolerances, ensuring the duct channels airflow exactly as specified for the DCA ultra-silent enclosure.
- Direct Replacement — Mounts to the rear cover of the generator enclosure using the original attachment points, matching the profile and dimensions of the factory component.
- Confirmed Fitment — Compatible with DCA150SSJU, DCA150SSJU2, DCA150SSVU, and DCA150SSVU-FEMA generator models.
- Thermal Management — Properly directing exhaust and cooling airflow through the rear enclosure helps prevent heat buildup that can shorten engine and alternator service life.
- Enclosure Integrity — Restores the rear cover to its original sealed configuration, which is critical to maintaining the noise-attenuation performance of the ultra-silent housing.
The rear cover duct directs airflow through the generator's sound-attenuated enclosure, routing hot exhaust and cooling air out of the unit in a controlled path. In ultra-silent generators like the DCA150SS series, precise airflow management is essential — a damaged or missing duct can cause heat to recirculate inside the enclosure, raising operating temperatures and stressing the engine and alternator. Replacing a worn or cracked duct with a genuine OEM part like the M3443300503 restores proper thermal performance and keeps the enclosure functioning as designed.
