The Multiquip C3494421504 Lining is a genuine OEM component designed for the DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, and DCA400SSI4F3PD series ultra-silent and super-silent diesel generators. As a factory-sourced replacement, this lining is manufactured to the exact material and dimensional specifications required by the original equipment, ensuring a correct installation without the guesswork. Multiquip C3494421504 covers the DCA400SSI4F/4F3/4F3PB generator family, making it the straightforward choice when servicing these units. Sourcing the correct OEM lining the first time protects the integrity of the enclosure system and keeps the generator performing as designed.
Key Features
- OEM Material Specification — Manufactured to the same acoustic and thermal material grade as the original lining, maintaining the enclosure's designed attenuation performance.
- Direct-Fit Installation — Cut and profiled to match the original enclosure cavity geometry of the DCA400SSI series, allowing straightforward panel-by-panel replacement.
- Broad DCA400SSI Series Coverage — Compatible with DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, and DCA400SSI4F3PD generator models, including the Sunbelt variant.
- Enclosure Integrity — A properly fitted lining is essential for sustaining the sound-suppression performance that defines the super-silent and ultra-silent rating of these generator enclosures.
- Genuine OEM Sourcing — Supplied as an authorized Multiquip OEM replacement, carrying the part number C3494421504 to confirm an exact match against the original bill of materials.
The lining in a super-silent or ultra-silent generator enclosure serves as the acoustic and thermal barrier between the diesel engine and the exterior panels. It absorbs and dissipates engine noise, helping the unit meet its rated sound level at the specified distance — a critical requirement on noise-sensitive jobsites, film sets, and urban installations. When the lining becomes damaged, compressed, or deteriorated, sound attenuation drops noticeably, the enclosure may retain more heat around internal components, and the generator can fall out of compliance with site noise restrictions. Replacing a worn lining with the correct OEM part restores the enclosure to its original performance rating.
