The Husqvarna 590398901 Filter Cover is a genuine OEM component designed for Husqvarna D30, S13, S26, S36, HTCD10, HTCD20, and T4000 dust and slurry equipment. This cover secures and protects the filtration system inside compatible Husqvarna dust extractors and floor grinder dust management units, ensuring the filter assembly stays correctly seated during operation. DHS Equipment supplies this part to help keep your equipment running at full capacity with an exact-fit OEM replacement.
Key Features
- Genuine OEM Filter Housing Integrity — Manufactured to Husqvarna's original specifications, this cover maintains the correct sealing pressure and alignment needed to protect the filter element from bypass and premature loading.
- Direct Drop-In Replacement — Engineered to match the original mounting points and retention geometry, this cover installs directly without modification on all compatible units.
- Broad Fitment Coverage — Compatible with the D30, S13, S26, S36, HTCD10, HTCD20, and T4000 dust extractors and dust management systems, covering a wide range of Husqvarna dust and slurry equipment in active use on the jobsite.
- Sustained Dust Containment Performance — A properly fitted filter cover keeps the filtration circuit sealed, maintaining suction efficiency and preventing unfiltered air from bypassing the filter — critical for HEPA-level dust capture compliance.
- Dust Exposure Risk Management — Intact filter housing components are essential to maintaining compliant dust extraction performance. A cracked or missing cover compromises the sealed system and can allow hazardous particulates to escape into the work environment.
The filter cover forms the outer housing closure for the dust extractor's filter assembly, holding the filter element securely in position and maintaining an airtight seal within the filtration chamber. When this cover is damaged, warped, or missing, the sealed airflow path is disrupted — unfiltered air can bypass the filter, reducing dust capture efficiency and exposing operators to fine silica and concrete particulates. Replacing a worn or broken cover with the correct OEM part restores the integrity of the filtration system and ensures the extractor performs to its rated dust collection specification.
