Multiquip 0602046531 Air Cleaner

The Multiquip 0602046531 is a genuine OEM Air Cleaner designed for DLW400ES series diesel light welder/generators, including the DLW400ES, DLW400ESA, and DLW400ESA1. As a direct Multiquip OEM part, it is built to the same specification as the original component installed at the factory, ensuring a correct, hassle-free installation on compatible equipment. If you are servicing a DLW400ES and need a dependable, properly fitting air cleaner, part number 0602046531 is the confirmed replacement.

Key Features

• Genuine OEM Filtration Specification — Matches the original air cleaner's filtration media grade and flow rating, ensuring the engine receives properly cleaned air without restriction.
• Direct-Fit Installation — Engineered to mount directly to the DLW400ES series air intake housing with no rework or adapter required.
• Confirmed Fitment — Compatible with DLW400ES, DLW400ESA, and DLW400ESA1 diesel light welder/generator models.
• Engine Protection — A clean, properly seated air cleaner prevents abrasive dust and debris from entering the engine, preserving cylinder and piston integrity over the long run.
• Correct Sealing Surface — The OEM housing geometry ensures a full, even seal against the intake, preventing unfiltered air bypass that can accelerate internal engine wear.

The air cleaner is responsible for filtering dust, dirt, and airborne debris out of the air entering the engine before combustion. On a diesel-powered welder/generator like the DLW400ES series, a functioning air cleaner is critical to maintaining engine efficiency and preventing premature wear on internal components. When the air cleaner becomes clogged or damaged, the engine may run lean, lose power output, or ingest contaminants that cause scoring inside the cylinder — making timely replacement an essential part of routine service.
