The Multiquip AF55309 Air Cleaner Element Secondary is a genuine OEM component designed for DCA300SSCU2 and DCA300SSCU4i diesel powered generators. As a direct OEM replacement, this element meets the exact filtration standards specified for these units, ensuring the air intake system performs exactly as engineered. Sourced directly from Multiquip, the part is the correct secondary element for confirmed fitment on DCA300SSCU2 and DCA300SSCU4i models.
Key Features
- Genuine OEM Filtration Media — Manufactured to the precise porosity and particle-capture rating required for DCA300SSCU2 and DCA300SSCU4i diesel generator air intake systems.
- Secondary-Stage Protection — Acts as a final barrier behind the primary element, catching fine particulates that pass through the outer filter and keeping contaminants out of the engine.
- Direct Drop-In Replacement — Matches the original housing dimensions and sealing surfaces for a clean, secure installation without adapters or rework.
- Confirmed Fitment — Verified for DCA300SSCU2 and DCA300SSCU4i super-silent diesel generators, eliminating guesswork when ordering service parts.
- Engine Longevity — A compromised or clogged secondary element allows abrasive particles into the combustion chamber; replacing it on schedule protects rings, cylinder walls, and valves from accelerated wear.
The secondary air cleaner element sits behind the primary filter in the air intake assembly and provides a last line of defense against fine dust and particulates before air enters the engine. On diesel generator sets like the DCA300SSCU2 and DCA300SSCU4i, clean intake air is critical to consistent combustion, fuel efficiency, and long engine life. When the secondary element becomes clogged or degraded, airflow is restricted and unfiltered particles can bypass the primary element, leading to increased engine wear and reduced output performance.
