The Multiquip M3494421404 is a genuine OEM Acoustic Sheet designed for the DCA180SSJU4F and DCA220SSJU4F Super-Silent Generator series. As a direct Multiquip OEM component, it is manufactured to the same specifications as the original part, ensuring a consistent fit within the generator enclosure. This sheet is confirmed compatible across multiple configurations of the Super-Silent Generator lineup, including 60Hz variants of the DCA180SSJU4F and DCA220SSJU4F families.
Key Features
- Genuine OEM Sound Dampening Material — Manufactured to the exact density and composition spec of the original, so the acoustic sheet performs as intended within the enclosure panel system.
- Drop-In Enclosure Fit — Sized and shaped to seat directly into the existing panel cavity without trimming or modification, preserving the integrity of the generator housing.
- Broad Super-Silent Series Coverage — Compatible with DCA180SSJU4F and DCA220SSJU4F generator models, including 60Hz configurations across multiple production variants.
- Noise Level Maintenance — A worn, torn, or missing acoustic sheet allows significantly more engine noise to escape the enclosure, which can violate jobsite noise ordinances and reduce operator comfort in noise-sensitive environments.
- Enclosure Structural Integrity — Properly fitted acoustic sheeting also provides a secondary layer of protection against vibration transfer to outer panels, helping maintain the overall condition of the generator cabinet over time.
An acoustic sheet is a noise-absorbing liner installed on the interior panels of a generator enclosure. Its primary role is to absorb and dampen the engine and alternator noise generated during operation, which is what gives Super-Silent generators their low-noise working characteristics. When this material degrades, becomes saturated, or is physically damaged, the enclosure's ability to contain sound is compromised — resulting in noticeably higher operational noise levels that may conflict with site regulations or rental fleet standards.
