The Multiquip M3494407304 Acoustic Sheet is a genuine OEM component designed for DCA150SSJU4F and DCA220SSJU4F super-silent generator models. Sourced directly from Multiquip, this part meets the original design specifications for sound attenuation in ultra-silent and super-silent enclosure configurations. It is a direct replacement for the factory-installed acoustic sheet, making it the correct choice for restoring noise reduction performance on DCA150SSJU4F and DCA220SSJU4F units, including 60Hz configurations.
Key Features
- Genuine OEM Sound Attenuation Material — Manufactured to the exact material grade and acoustic density specified for these enclosures, ensuring the sheet performs as the original did from day one.
- Direct Enclosure Fit — Dimensioned and profiled to match the original mounting location inside the generator enclosure, dropping into place without trimming or reworking the housing.
- Compatible with DCA150SSJU4F and DCA220SSJU4F — Verified fitment across both super-silent and diesel-powered generator variants, including DCA220SSJU4F 60Hz configurations.
- Restores Enclosure Noise Ratings — A degraded or missing acoustic sheet allows engine noise to breach the enclosure, pushing sound levels above rated dB(A) specs. Replacing it brings the unit back to its rated quiet operation.
- Regulatory and Site Compliance Support — Super-silent generators are frequently deployed on noise-sensitive sites governed by local sound ordinances. Maintaining intact acoustic lining helps keep the unit compliant with those requirements.
The acoustic sheet is a sound-dampening liner installed inside the generator's enclosure panels. It absorbs and dissipates engine and alternator noise before it can radiate through the outer housing, which is what allows super-silent generators to operate at their rated low decibel levels. When this material deteriorates, tears, or goes missing, the enclosure loses its acoustic effectiveness — noise levels rise, and the unit may no longer meet the sound specifications it was sold under. Replacing a worn acoustic sheet is a straightforward but critical step in any enclosure service or noise-related troubleshooting procedure.
