Key Features
- Genuine OEM Filtration Media — Engineered to the exact airflow and particle-capture specifications Multiquip requires for these engines, ensuring consistent combustion air quality.
- Drop-In Replacement — Matches the original mounting dimensions and sealing surface for a clean installation with no trimming or adapter hardware needed.
- Broad Model Coverage — Confirmed fit for WBH21EPA, WBH-16EAWD, WBH-16EAWDF, WBH-21EFP, WBH-21EF power buggies and the PRO20 stationary mixer.
- Protects Engine Performance — A clean, properly fitted filter maintains optimal air-to-fuel ratio, preventing premature wear on internal engine components caused by dust, debris, and silica common on concrete and masonry sites.
- Fuel Efficiency — A clogged or ill-fitting filter forces the engine to work harder and consume more fuel; replacing it on schedule keeps fuel consumption in check across long pours or heavy transport runs.
An air filter's job is to strip dust, concrete dust, and other airborne particles from the intake air before it reaches the engine's carburetor and combustion chamber. On worksites where concrete, aggregate, and silica are constantly in the air, the filter works hard and loads up quickly. When the filter becomes saturated or damaged, abrasive particles pass through and accelerate cylinder and valve wear, while restricted airflow causes the engine to run rich, lose power, and burn excess fuel. Replacing the Multiquip 394018S Air Filter at regular service intervals is one of the most cost-effective ways to extend engine life on your Whiteman power buggy or Essick PRO20 mixer.
