The Husqvarna 581774401 Air Cleaner System Fs5000D T4I is a genuine OEM component designed for the FS5000D floor saw. Sourced directly from Husqvarna, this air cleaner system meets the original engineering specifications for the FS5000D's Tier 4i engine configuration, ensuring the engine receives properly filtered air under the demanding conditions of concrete cutting. DHS Equipment supplies this part to help keep your floor saw operating at full capacity.
Key Features
- OEM Filtration Integrity — Engineered to Husqvarna's original filtration specifications for the FS5000D T4I engine, ensuring correct airflow volume and particle capture efficiency rather than a generic estimate.
- Exact-Match Assembly — This air cleaner system is designed to install directly into the FS5000D's existing mounting points and connections, requiring no modification to housings, brackets, or intake plumbing.
- FS5000D Floor Saw Compatibility — Confirmed fitment for the FS5000D floor saw, specifically the T4I engine variant, so you can order with confidence knowing this is the correct assembly for your machine.
- Engine Protection Under Load — A properly functioning air cleaner system prevents abrasive concrete dust and fine particulates from entering the engine, protecting cylinder walls, pistons, and rings during heavy slab-cutting work.
- Emissions Compliance Support — Designed for the Tier 4i engine specification, this system helps maintain the emissions control function the engine was certified with, keeping the machine compliant for regulated jobsite use.
The air cleaner system is the engine's first line of defense against airborne contaminants. On a floor saw like the FS5000D, the operating environment is especially harsh — concrete dust, slurry mist, and fine silica particles are constantly present near the intake. The air cleaner filters incoming air before it reaches the carburetor or fuel injection system, preventing abrasive material from entering the combustion chamber. When this system becomes clogged or damaged, the engine is forced to run lean or ingest contaminants, leading to accelerated wear, power loss, and potential engine failure. Replacing a worn or damaged air cleaner system with the correct OEM assembly restores proper airflow and keeps the FS5000D running at its rated output.
