Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design specifications, ensuring the duct channels and sealing surfaces match the enclosure geometry precisely.
- Direct Drop-In Replacement — Engineered to align with the existing mounting points and rear cover assembly, allowing straightforward installation without modification to surrounding panels.
- Confirmed Fitment — Compatible with DCA25SSIU2, DCA25SSIU2-60HZ, and DCA20SPX ultra-silent diesel generator models.
- Maintains Airflow Integrity — A properly seated rear cover duct directs cooling air through the correct internal pathways, protecting the engine and alternator from heat buildup during continuous operation.
- Enclosure Seal Performance — Correct duct fitment preserves the sound-attenuating design of the ultra-silent enclosure; a damaged or missing duct can compromise both thermal management and noise control.
The rear cover duct is an internal airflow management component housed within the generator's sound-attenuating enclosure. Its role is to direct air drawn in through the ventilation system toward the engine and alternator cooling zones, then guide exhaust heat out through the designated exit path. When this duct is cracked, missing, or improperly seated, conditioned airflow is disrupted — hot air can recirculate inside the enclosure, causing the generator to run hotter than designed and potentially triggering thermal shutdowns or accelerating wear on internal components.
