The Multiquip M1493400404 Acoustic Sheet is a genuine OEM component designed for DCA45SSIU and DCA36SPX series ultra-silent diesel generators. As a direct factory replacement, this part meets the original design specifications required to maintain the generator's sound-attenuation performance. It is confirmed compatible with DCA45SSIU2, DCA45SSIU3, DCA45SSIU4, DCA45SSIU3-50HZ, DCA45SSIU3-60HZ, DCA45SSIU2-FEMA, DCA45SSIU2-GEER, and DCA36SPX models. Sourcing a genuine OEM Acoustic Sheet ensures the enclosure performs exactly as engineered — no guesswork on material grade or dimensional fit.
Key Features
- Genuine OEM Sound Damping Material — Manufactured to the original noise-reduction specification, ensuring the acoustic lining absorbs and contains engine noise at the correct frequency range for these enclosures.
- Drop-In Enclosure Fit — Dimensioned to match the original panel location within the generator housing, allowing straightforward removal and reinstallation without trimming or modification.
- Broad DCA Series Compatibility — Fits DCA45SSIU2, DCA45SSIU3, DCA45SSIU4, DCA36SPX, and regional variants including 50Hz, 60Hz, FEMA, and GEER configurations.
- Preserves Low-dB Operating Ratings — A degraded or missing acoustic sheet allows sound levels to rise beyond rated dB output, which can violate noise ordinances on sensitive jobsites such as film sets, hospitals, or residential areas where these ultra-silent units are commonly deployed.
- Noise Compliance Support — Restoring the acoustic lining to OEM condition is essential for generators required to operate within permitted sound limits — a direct factor in regulatory and contractual compliance on noise-restricted sites.
The Acoustic Sheet is a sound-dampening liner bonded or fitted within the generator's enclosure panels. Its role is to absorb vibration and engine noise before it radiates outward, which is what allows ultra-silent generators like the DCA series to operate at low decibel ratings in noise-sensitive environments. When the sheet deteriorates, tears, or is missing, the enclosure loses its sound-attenuating properties and the generator will exceed its rated noise level — potentially making it unsuitable for the applications it was specified for.
