Key Features
- OEM Filtration Integrity — Built to Husqvarna's original filtration specification, this air cleaner delivers the correct particulate barrier for concrete cutting environments where dust loads are high.
- Drop-In Replacement — Engineered to match the original mounting points and housing dimensions, this air cleaner installs directly without modification to brackets or fittings.
- Confirmed Floor Saw Fitment — Compatible with FS513, FS520, and FS524 floor saws; verify against your machine's parts diagram using part number 577802701.
- Engine Protection in Dusty Conditions — A properly functioning air cleaner prevents abrasive concrete dust from entering the engine, maintaining compression and protecting internal components over the long haul.
- Fuel and Air System Compliance — Using a genuine OEM air cleaner ensures the air-fuel mixture remains within the engine's designed operating range, supporting consistent power output and helping prevent lean-running damage.
The air cleaner is responsible for filtering out dust, debris, and airborne particulates before they reach the engine's intake. In floor saw applications, where the machine operates close to concrete surfaces generating heavy silica dust, a clean and correctly sealing air cleaner is critical — a clogged or degraded unit restricts airflow, causes the engine to run rich, reduces power, and accelerates wear on cylinder walls and piston rings. Replacing a worn air cleaner with a genuine OEM unit restores proper airflow volume and filtration efficiency, helping the engine perform as designed across demanding cutting cycles.
