The Multiquip 393957S Air Cleaner WM-120 is a genuine OEM air cleaner designed for the WM120 Whiteman plaster and mortar mixer. Sourced directly from Multiquip, this part matches the original specification for a straight-forward, bolt-in installation with no adaptation needed. If you're servicing a WM120 mixer, the part is the correct OEM-verified replacement to restore proper engine air filtration.
Key Features
- OEM Filtration Integrity — Engineered to the exact filter media grade and housing seal spec of the original, ensuring the engine receives properly filtered air rather than a compromised flow path.
- Direct-Mount Replacement — Designed to seat and secure exactly as the factory unit does on the WM120, with matching mounting points and inlet dimensions for a clean swap.
- WM120 Specific Fitment — Built specifically for the Whiteman WM120 mortar and plaster mixer; confirm your model code before ordering to ensure correct application.
- Protects Engine Longevity — A functioning air cleaner keeps abrasive dust, aggregate particles, and job site debris out of the combustion chamber, directly protecting piston rings and cylinder walls from premature wear.
- Fuel Efficiency and Clean Running — A clean, properly sealing air cleaner maintains the correct air-to-fuel ratio, helping the engine run efficiently and avoid rough idling or black smoke caused by a restricted or leaking unit.
The air cleaner on a mortar mixer engine serves as the first line of defense against the dusty, particulate-heavy environments these machines typically operate in. It filters incoming combustion air before it reaches the carburetor and engine internals, preventing abrasive material from accelerating wear on critical engine components. When an air cleaner becomes clogged, damaged, or fails to seal correctly, the engine loses power, runs rich, consumes more fuel, and over time suffers accelerated internal wear — making timely replacement essential to keeping the WM120 running at full capacity.
