Multiquip PMAF25436 Cartridge Air Cleaner

The Multiquip PMAF25436 Cartridge Air Cleaner is a genuine OEM component designed for the DLW500ESA4 diesel light welder and HTXD6i, STXD6i, HTX44Y4, and HTX44Y5 hydrostatic ride-on power trowels. As a direct OEM replacement, PMAF25436 meets the exact filtration specifications required by the Yanmar 4TNV84T-DSA engine found across these machine families. Sourced directly from Multiquip, this cartridge ensures your air intake system performs as the engine was engineered to demand. Verify your model code before ordering to confirm compatibility with your specific unit.

Key Features

• OEM Filtration Specification: — Engineered to the exact particulate capture rating and airflow resistance required by the Yanmar 4TNV84T-DSA engine — not a generic approximation.
• Drop-In Cartridge Fit: — Replaces the original filter housing insert directly, with no trimming or adapter hardware needed for the supported models.
• Broad Model Coverage: — Confirmed fitment across DLW500ESA4, HTXD6i, STXD6i, HTX44Y4, and HTX44Y5 equipment, covering both welder and hydrostatic trowel applications sharing the same engine platform.
• Engine Protection Where It Counts: — A correctly functioning air cleaner keeps abrasive dust and debris out of the combustion chamber; a clogged or failed cartridge accelerates cylinder wear and raises fuel consumption on demanding concrete finishing and welding applications.
• Fuel System Safety Compliance: — Maintaining a properly sealed, OEM-rated air filtration element supports correct air-fuel mixture at the injectors, protecting the fuel system from running lean under load.

The air cleaner cartridge is the primary barrier between the engine's intake and the airborne contaminants generated on active construction sites — concrete dust, soil particulate, and exhaust debris. On Yanmar-powered equipment like the HTXD6i and STXD6i trowels and the DLW500ESA4 welder, the cartridge sits within the air cleaner housing and filters incoming air before it reaches the turbocharger and combustion chamber. When the cartridge becomes saturated or damaged, restricted airflow causes the engine to run rich, lose power, and generate excessive heat — shortening engine life and increasing operating costs. Replacing it on schedule with a genuine OEM cartridge like the PMAF25436 keeps combustion clean and consistent across the service life of the machine.
