Multiquip HS018600056AR Air Inner Filter

The Multiquip HS018600056AR Air Inner Filter is a genuine OEM component designed for HS62A, SHS62A, HS81A, and SHS81A high-speed cut-off saws. As a direct OEM replacement, this filter is manufactured to the same specification as the original, ensuring a correct fit and consistent air filtration performance in demanding cutting applications. Sourced directly through Multiquip's authorized parts program, it is the right choice for operators who depend on their cut-off saw to perform reliably through heavy use on concrete, masonry, and pavement.

Key Features

• Genuine OEM Filtration Media: — Manufactured to original specification, ensuring the inner filter element provides the same particle capture efficiency as the factory-installed unit — critical in dust-heavy cut-off saw environments.
• Direct Drop-In Fit: — Engineered to seat correctly within the existing air filter housing on compatible saws, requiring no trimming or adaptation during installation.
• Broad Sidewinder Series Compatibility: — Fits HS62A, SHS62A, HS81A, and SHS81A MQ and STOW high-speed cut-off saws, covering both MQ and STOW Sidewinder variants.
• Protects Engine from Contaminant Ingestion: — The inner filter acts as a secondary barrier against fine dust and debris, preventing abrasive particles from reaching the carburetor and engine internals where they cause accelerated wear.
• Supports Proper Fuel-Air Mixture: — A clean, unobstructed inner filter allows the engine to draw the correct air volume for efficient combustion — a clogged or degraded filter leads to rich running, power loss, and hard starting.

The air inner filter is the secondary filtration stage in a two-stage air cleaner system. While the outer pre-filter captures larger debris and dust, the inner filter traps fine particles before air enters the carburetor and combustion chamber. In cut-off saw applications — where concrete dust, silica, and abrasive particulates are constantly generated — this inner element plays a critical role in protecting engine longevity. When the inner filter becomes clogged or damaged, airflow is restricted, causing the engine to run rich, lose power, and potentially overheat; in severe cases, contaminants can pass through and score cylinder walls, leading to costly engine damage.
