Key Features
- Genuine OEM Filtration Media — Manufactured to Husqvarna's specified filtration grade, this prefilter captures coarse dust particles before they reach the main filter, maintaining the system's designed airflow and dust capture efficiency.
- Direct Drop-In Replacement — Engineered to match the original mounting interface on DURATIQ, HTC, and PG floor grinders, this prefilter seats correctly without trimming or reworking the filter housing.
- Broad Floor Grinder Compatibility — Fits a wide range of Husqvarna floor grinder families including DURATIQT5, DURATIQT6, DURATIQX6, DURATIQX8, HTCT5, HTCT8, HTCX8, HTCXP6, HTCRX8, PG5, PG8D, PG8DR, and PG8XR.
- Protects Primary Filter Life — By intercepting heavy dust load before it reaches the main filter element, a properly functioning prefilter extends the service interval of the more costly downstream filter.
- Dust Exposure Compliance — Maintaining an intact, correctly fitted prefilter is a key part of keeping the grinder's dust extraction system working as intended, supporting compliance with silica and concrete dust exposure controls on the jobsite.
A prefilter sits upstream of the machine's primary filter element in the dust extraction path, acting as the first stage of particulate capture. It intercepts larger dust and debris particles generated during floor grinding, preventing premature clogging of the main filter and sustaining consistent airflow through the dust management system. When the prefilter becomes saturated or damaged, airflow restriction increases, extraction performance drops, and the primary filter is exposed to heavier contamination than it is designed to handle — accelerating wear and increasing dust escape at the work surface.
