Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original design specifications, ensuring the duct maintains proper airflow geometry and structural integrity within the enclosure.
• Direct Drop-In Replacement — Engineered to align with the existing mounting points and frame channels of compatible DCA super-silent generator enclosures for a straightforward swap.
• Broad DCA Series Compatibility — Confirmed fitment across DCA150SSJU4F2, DCA150SSJU4F3, DCA180SSJU4F3, DCA220SSJU4F2, and DCA220SSJU4F3 models, including 60Hz variants.
• Enclosure Airflow Integrity — Properly channels cooling air through the rear frame section of the generator enclosure, helping the engine and alternator maintain safe operating temperatures under load.
• Acoustic Performance Preservation — A correctly fitted frame duct maintains the sealed enclosure design that gives DCA super-silent generators their low-decibel operating characteristics — a damaged or missing duct can compromise sound attenuation.

The Rear Frame Duct is a structural and airflow management component housed within the generator's sound-attenuating enclosure. It directs cooling air along the rear frame section, ensuring heat generated by the engine and alternator is efficiently routed out of the enclosure without creating hot spots or disrupting the acoustic baffling. When this duct is cracked, deformed, or missing, airflow paths inside the enclosure become uncontrolled, which can lead to elevated operating temperatures and a reduction in the sound-dampening performance that DCA super-silent generators are built to deliver.
