Multiquip DZ118548 DEF Inline Filter John Deere - OEM Replacement Part

The DEF inline filter protects the Diesel Exhaust Fluid system from contamination, ensuring proper operation of the emissions control components on John Deere-powered Multiquip generator sets. This filter prevents particulates and debris from reaching critical DEF system components, maintaining the integrity of the regeneration process that occurs automatically every 96 hours at 1,800 rpm engine speed. Failed or clogged DEF filters can trigger system faults, prevent proper DPF regeneration cycles, and potentially shut down generator operation.

The DEF system is essential for exhaust after-treatment on these Tier 4 Final compliant super silent generators. Regular replacement of this inline filter helps prevent costly DEF system failures and ensures compliance with emissions standards. When servicing the DEF system, always allow at least two minutes for system regeneration to complete before shutting down the unit, as outlined in the operation manual shutdown procedures.

Compatible with the following Multiquip generator models:

• DCA300SSJU4F3
• DCA300SSJU4F3PD
• DCA70SSJU4F
