HEPA filter element for CT dust extractors describes a Festool filter designed as the main filtration stage for CT 26 E, CT 36 E, CT 48 E, CT 36 AC, and CT 48 AC units. This element filters particles down to 0.3 microns, so fine sanding dust and other small airborne particles are captured at the extractor rather than staying in the workspace. Festool defines this as its highest standard for filtration, which sets a consistent performance level across compatible CT models. The filter is identified as a HEPA main filter for CT 36 AC and CT 48 AC in the product description, tying directly to those automatic clean models in shops already standardized on them. The Festool 205412 part number gives installers a clear reference when matching existing CT units or documenting service and replacement schedules in a professional setting.
The product is specified as a HEPA main filter for CT 36 AC and CT 48 AC, which defines its role as the core filtration element in those Festool dust extractors. The same filter is described as fitting CT 26 E, CT 36 E, and CT 48 E, so a single part covers both E-series and AC-series machines in that size range. Using one part number, Festool 205412, across these models simplifies filter changes, because technicians can match the number in service records and inventory systems. The filtration rating down to 0.3 microns establishes that this filter is intended for fine dust extraction duties, so it supports extraction performance when installed in compatible CT units during routine service.
The web description states that this HEPA filter fits CT 26 E, CT 36 E, and CT 48 E dust extractors, aligning directly with common Festool shop vac sizes. That allows one filter type to serve small, medium, and larger-capacity CT E units on the same floor. The SAP description calls it a HEPA main filter for CT 36 AC and CT 48 AC, tying it to the automatic clean variants that share similar body formats. Because the same Festool 205412 part works across this group, shops running mixed CT 26 E, CT 36 E, CT 48 E, CT 36 AC, and CT 48 AC systems can rely on a single stocked filter element. This reduces part confusion when moving units between stations or assigning units to different trades within the same facility.
The filter is described as Festool's highest standard for filtration, so when it is in place the CT dust extractor operates at the filtration level the manufacturer targets for these models. Its ability to filter particles to 0.3 microns means fine sanding dust is captured in the extractor, supporting clearer visibility at the work area and reducing dust settling back on freshly machined parts. By serving as the HEPA main filter in CT 36 AC and CT 48 AC units, it anchors the extraction performance in applications where automatic filter cleaning is used to maintain airflow. The shared 205412 part number across CT 26 E, CT 36 E, CT 48 E, CT 36 AC, and CT 48 AC simplifies scheduled replacement, helping maintain consistent dust control across multiple machines without separate filter specifications.
The Festool 205412 HEPA filter element fits CT 26 E, CT 36 E, CT 48 E, CT 36 AC, and CT 48 AC dust extractors, so one filter can serve multiple extractor sizes in a shop.
The HEPA filter element for CT dust extractors captures particles to 0.3 microns, so very fine sanding and cutting dust is retained inside the CT unit rather than remaining airborne around the work.
The filter is identified by Festool part number 205412 and by its SAP description as a HEPA main filter for CT 36 AC and CT 48 AC, which supports clear reordering and inventory tracking.
In CT 36 AC and CT 48 AC extractors, the Festool 205412 element functions as the HEPA main filter, providing the primary fine dust filtration stage during extraction.
The web description states that this is Festool's highest standard for filtration, so it sets the filtration level these CT dust extractors are designed to use during operation.
Because the Festool 205412 HEPA filter fits CT 26 E, CT 36 E, CT 48 E, CT 36 AC, and CT 48 AC, a shop can stock a single filter type for these units to coordinate maintenance.
The Festool HEPA filter element described here is specified as the HEPA main filter for CT 36 AC and CT 48 AC and is also listed as fitting CT 26 E, CT 36 E, and CT 48 E dust extractors. Its filtration capability down to 0.3 microns and designation as Festool's highest standard for filtration define its performance role inside these units. Using the Festool 205412 part across these CT models lets shops align extractor upkeep to a single HEPA filter standard. For CT 26 E, CT 36 E, CT 48 E, CT 36 AC, and CT 48 AC systems that match this description, this HEPA filter element for CT dust extractors is the specified option to support that level of dust control.
