Key Features
- Genuine OEM Construction — Produced to the exact material and dimensional standards required for this lining application, ensuring consistent performance within the DCA400SSI generator enclosure system.
- Direct-Fit Replacement — Engineered to drop into position without alteration, matching the original mounting configuration of the DCA400SSI4F and DCA400SSI4F3 series.
- Broad DCA400SSI Series Coverage — Fits DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, DCA400SSI4F3PD, DCA400SSI4F3B, and Sunbelt-designated DCA400SSI4F3PD units.
- Enclosure Integrity — A correctly fitted lining maintains the acoustic and thermal performance of the Super-Silent enclosure, supporting quiet operation on noise-sensitive jobsites.
- Sourced from Multiquip — Supplied as genuine Multiquip OEM stock, so the part number, fit, and material grade match what was installed at the factory.
The lining in a Super-Silent generator enclosure serves as an acoustic and thermal barrier between the engine compartment and the outer housing. It absorbs sound energy generated by the diesel engine and drivetrain, which is what allows DCA400SSI-series units to operate at reduced decibel levels in sound-sensitive environments. When the lining becomes damaged, compressed, or deteriorated, the enclosure loses its noise-attenuating effectiveness and the generator may exceed acceptable sound thresholds — making timely replacement important for both operational compliance and site suitability.
