Multiquip 6125817032 Air Filter Inner

The Multiquip 6125817032 Air Filter Inner is a genuine OEM replacement designed for DCA-220SSK, DCA-300SSK, DCA600SSK, and related DCA Super-Silent and Ultra-Silent series diesel generators. As a factory-sourced component, it meets the exact filtration specifications required by Multiquip for these generator platforms. Verify your model code against the fitment list — this inner filter is confirmed across the broad DCA SSK and SSV generator family. Sourcing the correct OEM part by number ensures your engine air intake system performs exactly as engineered.

Key Features

• OEM Filtration Specification — Manufactured to the exact pore density and media grade specified for DCA-series diesel engines, ensuring correct particulate capture without restricting airflow.
• Two-Stage Inner Element — Functions as the secondary filtration layer inside the outer filter housing, trapping fine particles that pass the outer element before they reach the engine intake.
• Broad DCA Generator Fitment — Confirmed for DCA-220SSK, DCA-300SSK, DCA-300SSK2, DCA-300SSK3, DCA600SSK, DCA500SSK, DCA800SSK, DCA125SSJU, and DCA600SSV models.
• Engine Protection Under Load — A fully functioning inner air filter prevents fine abrasive dust from entering cylinder walls and turbocharger passages during continuous generator operation — worn or collapsed elements accelerate internal engine wear.
• Direct Housing Fit — Sized to seat correctly within the OEM air cleaner assembly without shimming or trimming, maintaining the sealed fit the housing is designed to deliver.

The inner air filter serves as the final line of defense in a two-stage engine air filtration system. Its job is to capture fine dust particles that bypass the outer pre-cleaner element, preventing abrasive contaminants from entering the engine's combustion chambers, injectors, and turbocharger. In diesel-powered generators that run continuously under load — as DCA-series units are designed to do — a clogged or degraded inner element restricts airflow, causes the engine to run rich, and accelerates wear on precision internal components. Replacing the inner filter on schedule with the correct OEM part maintains combustion efficiency and protects the engine's long-term service life.
