The Multiquip M2443300513 Rear Cover Duct is a genuine OEM component designed for DCA-series ultra-silent diesel generators including the DCA70SSJU, DCA70SSJU2, DCA70SSJU3, DCA70SSJU-GEER, and DCA70SSIU2-FEMA. As an authorized Multiquip parts dealer, DHS Equipment sources this duct directly from the manufacturer to ensure exact dimensional and material conformance. Replacing a damaged or deteriorated duct with the correct OEM part keeps airflow management within the enclosure operating as engineered, supporting consistent generator output and thermal regulation.
Key Features
- Genuine OEM Airflow Integrity — Manufactured to Multiquip's exact enclosure specifications, ensuring the duct channels cooling air through the rear cover section precisely as designed for the DCA70SS platform.
- Direct-Fit Replacement — Engineered to align with the existing mounting points and cover geometry on DCA70SSJU and DCA70SSIU2 series units, requiring no cutting or modification to the enclosure.
- Broad DCA70SS Series Coverage — Confirmed fitment across DCA70SSJU, DCA70SSJU2, DCA70SSJU3, DCA70SSJU-GEER, and DCA70SSIU2-FEMA generator models.
- Thermal Management Protection — A properly seated rear cover duct prevents hot air recirculation inside the enclosure, protecting the engine and alternator from heat buildup during sustained operation.
- Enclosure Compliance — Maintains the acoustic and ventilation performance of the ultra-silent enclosure design; a cracked or missing duct can compromise both sound attenuation and internal temperature control.
The rear cover duct is a formed airflow channel mounted within the generator's sound-attenuating enclosure. Its role is to direct cooling air from the intake through the enclosure and out through the rear, preventing hot exhaust air from recirculating back over the engine and alternator. When this duct cracks, deforms, or goes missing, airflow separation breaks down inside the enclosure — leading to elevated operating temperatures, potential thermal shutdowns, and accelerated wear on internal components. Replacing it with the correct OEM part, Multiquip M2443300513, restores the designed ventilation path and keeps the generator running within its intended thermal limits.
