The Multiquip 5303604 DEF Supply Module Filter is a genuine OEM component designed for SG1400C4F and SG1600C4F diesel-powered studio generators. Sourced directly from Multiquip, this filter meets the exact specifications required by the DEF supply system on these Tier 4 Final units. It is a direct-fit replacement that installs into the DEF supply module without alteration, keeping your emissions system operating within compliance parameters. Confirm your generator model code before ordering to ensure correct application.
Key Features
- Genuine OEM Filtration Media — manufactured to the same specification as the original, ensuring consistent DEF flow rate and particulate capture performance within the supply module.
- Direct-Fit Replacement — engineered to seat correctly within the DEF supply module housing on compatible Multiquip studio generators, with no rework or adaptation to the mounting interface.
- Confirmed Fitment — verified for use on the Multiquip SG1400C4F and SG1600C4F Tier 4 Final studio generator models.
- Protects Dosing Components — a clean, functioning DEF filter prevents contaminants from reaching the dosing pump and injector, which are sensitive and costly to replace if compromised.
- Emissions System Compliance — maintaining a serviceable DEF supply module filter is essential for Tier 4 Final emissions compliance; a blocked or degraded filter can trigger fault codes and force the generator into derate or shutdown mode.
The DEF supply module filter is a critical serviceable component within the diesel exhaust fluid (DEF) delivery system on Tier 4 Final generators. It screens out particulates and contaminants before DEF reaches the dosing pump and SCR injector, protecting precision components from abrasive wear and blockage. When this filter becomes clogged or degraded, DEF flow is restricted, which can trigger warning codes, cause the SCR system to underperform, and ultimately force the generator into a power derate or non-start condition to remain within emissions regulations.
