Key Features
- OEM Filtration Media: Manufactured to original specification, delivering the correct airflow restriction and filtration efficiency for Kubota and Yanmar engine applications found in the HTX44 series.
- Cross-Equipment Compatibility: A single part number covering both MQ62TK trash pumps and HTX44K4, HTX44K5, HTX44Y4, and HTX44Y5 ride-on power trowels — simplifying your parts inventory.
- Direct-Fit Replacement: Matches the original housing dimensions and seating interface, seating securely without gaps or adapter hardware.
- Engine Protection: A properly functioning air filter keeps abrasive dust and debris out of the combustion chamber, directly protecting piston rings, cylinder walls, and valve seats from accelerated wear.
- Genuine Multiquip OEM Part: Supplied by DHS Equipment as an authorized dealer — what you order is exactly what the machine was built to run.
The air filter's job is to prevent airborne contaminants — dust, debris, and fine particles common on concrete finishing and pump jobsites — from entering the engine's intake and combustion chamber. A clean, properly seating filter allows the engine to breathe freely while blocking particles that would otherwise score cylinder walls and accelerate internal wear. When an air filter becomes clogged or damaged, the engine runs rich, loses power, increases fuel consumption, and risks long-term internal damage — making timely filter replacement one of the most cost-effective maintenance tasks on any engine-powered equipment.
