The Multiquip M4493403104 Acoustic Sheet is a genuine OEM component designed for DCA220SSJ, DCA220SSJU, and DCA180SSJU ultra-silent diesel generators. Sourced directly from Multiquip, this part meets the exact material and dimensional requirements of the original, ensuring it installs correctly within the generator enclosure without modification. It is confirmed compatible with DCA-series ultra-silent models and is the correct OEM choice for restoring sound attenuation performance to specification.
Key Features
- Genuine OEM Sound Attenuation Material — manufactured to the same density and acoustic absorption rating as the original, maintaining the enclosure's noise suppression design.
- Direct Drop-In Replacement — matches the original panel dimensions and mounting configuration for the DCA220SSJ, DCA220SSJU, and DCA180SSJU enclosures.
- Confirmed Fitment for DCA Ultra-Silent Series — verified for use on DCA220SSJ, DCA220SSJU, and DCA180SSJU Isuzu-powered ultra-silent generators.
- Restores Enclosure Noise Levels — a degraded or missing acoustic sheet allows sound to escape through the enclosure panels; replacing it brings noise output back to the generator's rated ultra-silent performance level.
- Operational Compliance for Noise-Sensitive Sites — ultra-silent generators are frequently deployed on film sets, urban job sites, and locations with strict noise ordinances; maintaining the acoustic lining keeps the unit within its rated dB range for those environments.
The acoustic sheet is a sound-dampening liner fitted inside the generator's enclosure panels. It absorbs and dissipates mechanical and combustion noise generated by the engine and alternator, which is what allows DCA ultra-silent generators to operate at significantly lower decibel levels than open-frame units. When this material deteriorates, compresses, or becomes damaged, the enclosure loses its ability to contain sound effectively, and the generator may no longer meet the noise thresholds required for sensitive or regulated work environments. Replacing the acoustic sheet with a genuine OEM part restores the enclosure to its designed performance standard.
