The Multiquip M3331400604 DPF Band is a genuine OEM component designed for the DCA150SSJU4F, DCA180SSJU4F, and DCA220SSJU4F series ultra-silent diesel generators. As a direct OEM replacement, it is manufactured to the same specifications as the original part, ensuring a proper fit within the exhaust aftertreatment system. This part is compatible across multiple variants of the DCA SSJU4F generator lineup, including 60Hz configurations and second- and third-generation models. Sourced directly through authorized Multiquip channels, the M3331400604 is a stock replacement you can trust to restore your machine to correct operating condition.

Key Features

• Genuine OEM Construction — Manufactured to the exact material and dimensional tolerances required for secure DPF retention in high-heat exhaust environments.
• Direct Drop-In Replacement — Mounts to the existing DPF housing using the original hardware positions, requiring no reworking of surrounding exhaust components.
• Broad DCA Series Compatibility — Fits DCA150SSJU4F, DCA180SSJU4F, and DCA220SSJU4F models, including 60Hz variants and F2/F3 generation units.
• Emission System Integrity — A correctly fitted DPF band maintains the seal and positioning of the diesel particulate filter, supporting proper exhaust aftertreatment function and emissions compliance.
• Exhaust Safety Retention — Secures the DPF canister firmly in place, preventing movement or misalignment that could compromise exhaust routing or create a burn hazard around the unit.

The DPF Band is a clamping or retention component that secures the diesel particulate filter (DPF) canister within the exhaust aftertreatment system of a diesel-powered generator. The DPF itself captures soot and particulate matter from engine exhaust, and the band holds it firmly in the correct position to maintain proper exhaust flow and system pressure. If the band becomes cracked, corroded, or loose, the DPF can shift or leak exhaust gases, compromising emissions performance and potentially triggering fault codes that take the generator offline.
