The Multiquip M3493306104 Acoustic Liner is a genuine OEM component designed for DCA150USJ3CAN and DCA150USJ2 series ultra-silent diesel powered generators. As a direct factory replacement, this liner matches the original material composition and dimensional profile specified for these units, ensuring it seats and performs exactly as intended. It is confirmed compatible with both the DCA150USJ2 and DCA150USJ3CAN variants, including the Canadian French-market DCA150USJ3CAN (FR) configuration. Sourcing the correct OEM liner by part number M3493306104 eliminates the guesswork and keeps your generator performing to its rated noise-attenuation specification.
Key Features
- Genuine OEM Sound Attenuation Material — Manufactured to the same acoustic absorption specification as the original, maintaining the rated noise-reduction performance of the enclosure.
- Direct Panel Replacement — Contoured to match the original mounting surfaces inside the generator canopy, allowing straightforward removal of the worn liner and installation of the new one without trimming or modification.
- Confirmed Fitment — Verified for DCA150USJ2, DCA150USJ3CAN, and DCA150USJ3CAN (FR) ultra-silent diesel powered generators.
- Preserves Ultra-Silent Rating — A degraded or missing acoustic liner causes audible noise levels to climb above the generator's rated output, which can violate site noise ordinances and disrupt sound-sensitive work environments.
- Enclosure Integrity Compliance — Replacing a deteriorated liner restores the full acoustic enclosure to its designed specification, which is especially critical on generators deployed on broadcast, film, or urban construction sites with strict noise limits.
An acoustic liner is an absorbent panel fitted to the interior walls of a generator's sound-attenuating enclosure. It works by converting mechanical and combustion noise energy into heat as sound waves pass through its surface, preventing that energy from radiating outside the canopy. Over time, vibration, heat cycling, and moisture exposure cause the liner material to compress, crack, or delaminate, reducing its ability to absorb sound and allowing noise levels to rise. Replacing a worn liner with the correct OEM part restores the enclosure to its designed attenuation performance and keeps the generator compliant with site noise requirements.
