Ordering by part number AF55308 ensures you receive the exact component engineered for these units.
Key Features
- Genuine OEM Filtration Media — Built to the same material and porosity specifications as the original, ensuring consistent particulate capture efficiency for diesel generator applications.
- Drop-In Secondary Stage Fit — Engineered to seat correctly within the secondary air cleaner housing, maintaining a proper seal and preventing bypass of unfiltered air.
- Confirmed Fitment — Verified for SG1400C4F, SG1600C4F, and DCA150SSCU4i diesel-powered generator models.
- Protects Engine Internals — The secondary filter acts as a safety barrier behind the primary element, catching any fine particles that pass through — keeping combustion air clean under demanding operating conditions.
- Supports Scheduled Maintenance Intervals — Replacing this filter on time preserves air-to-fuel ratios and helps the generator maintain stable power output across continuous-duty cycles.
The secondary air cleaner serves as the final stage of filtration in a two-stage air intake system. While the primary filter captures the bulk of dust and debris, the secondary element catches finer particulates that get through, protecting the engine's combustion chamber, pistons, and cylinder walls from abrasive wear. When the secondary filter becomes clogged or compromised, airflow to the engine is restricted, which can cause rough running, increased fuel consumption, and long-term internal engine damage — making timely replacement an important part of generator upkeep.
