Key Features
- OEM Sound-Dampening Material — Manufactured to the precise density and composition Multiquip specifies for effective noise attenuation inside the generator enclosure.
- Drop-In Panel Replacement — Sized and profiled to fit the existing enclosure mounting points on compatible DCA and NGA models without trimming or modification.
- Broad Generator Compatibility — Fits DCA150SSJU4F, DCA220SSJU4F, DCA150SSCU4i, DCA220SSCU, DCA220SSCU4I, NGA150SSPUPL, NGA150SSPUPL2, and DCA220SSJU4F 60Hz models.
- Enclosure Integrity — Restores the full acoustic barrier of the super-silent housing, ensuring the generator continues to meet the low-noise operating profile these units are specified for.
- Genuine OEM Part — Sourced directly from Multiquip, carrying part number M4493302904, so you receive the same component installed at the factory — not an approximation.
The Acoustic Sheet is a sound-absorbing panel fitted inside the enclosure of super-silent generator units. Its role is to absorb and dampen mechanical and combustion noise generated by the engine and alternator, allowing the generator to operate at the reduced decibel levels these models are rated and specified for on noise-sensitive jobsites. When this sheet deteriorates, tears, or goes missing, the enclosure loses its acoustic integrity and overall sound output increases — which can put the unit out of compliance with site noise regulations and affect its suitability for use in residential, studio, or indoor applications.
