Multiquip M113621 Air Filter HTN

The Multiquip M113621 Air Filter HTN is a genuine OEM replacement designed for AR13D, HHXD5, HHXD5-ES, and HHXG5 series equipment. As a direct Multiquip OEM part, the M113621 meets the exact specifications required for these machines, ensuring proper fit and function right out of the box. Verified fitment covers the AR13D roller and the Whiteman ride-on power trowel lineup including the HHXD5, HHXD5-ES, and HHXG5 models.

Key Features

• Genuine OEM Filtration Media — Built to the same filtration efficiency specification as the original, ensuring the engine receives clean, correctly conditioned airflow.
• Direct-Fit Installation — Engineered to seat and seal exactly like the factory part, with no trimming or adapter hardware needed for the air intake housing on compatible machines.
• Broad Multiquip Fitment — Confirmed for AR13D, HHXD5, HHXD5-ES, and HHXG5 models, covering both the roller and Whiteman ride-on trowel families in one part number.
• Engine Protection You Can Count On — A properly functioning air filter blocks dust, concrete particulate, and debris from entering the combustion chamber — a worn or clogged filter accelerates engine wear and reduces power output.
• Fuel Efficiency Maintained — A clean, correctly sized filter supports the proper air-to-fuel ratio, helping the engine run efficiently and avoid the rich-running conditions caused by restricted airflow.

An air filter is the engine's first line of defense against airborne contaminants. It removes dust, dirt, and fine debris from incoming air before it reaches the carburetor or fuel injection system, protecting internal engine components from abrasive wear. On worksites where concrete dust and loose aggregate are constant, a degraded or improperly fitting filter can allow damaging particles into the engine, leading to accelerated cylinder wear, reduced compression, and ultimately costly engine repairs.
