At a Glance: 20 litre cyclone pre-separator for Festool CT 26, CT 36 and CT 48 dust extractors, designed to reduce filter load during high dust and chip extraction.
The Festool CT-VA-20 CT pre-separator is a smart dust extraction accessory designed for work that produces high volumes of dust, shavings and chips. Using cyclone technology, it separates a large portion of dust and debris before it reaches the mobile dust extractor. This helps reduce load on the main filter, keeps suction performance more consistent and makes disposal of large dust volumes easier. It is ideal for sawing, routing, planing, diamond grinding, renovation milling and other demanding dust-heavy applications.
Cyclone pre-separation for cleaner, more consistent extraction
The CT-VA-20 is designed to sit between the power tool and the Festool CT extractor. Dust and chips enter the pre-separator first, where cyclone separation collects much of the material in the container before it reaches the extractor filter bag. That means better suction consistency, less filter clogging and easier handling when large amounts of dust are produced.
Product highlights
Cyclone technology: Helps cope with high volumes of dust, shavings and chips before they reach the extractor.
Maintains suction performance: Reduces the load on the mobile dust extractor’s main filter.
Up to 95% separation: Separates a high percentage of coarse particles such as sawing chips into the collection container.
Ideal for dust-heavy work: Especially useful with saws, routers, planers, diamond grinders and renovation millers.
For CT 26/36/48: Suitable for Festool CT 26, CT 36 and CT 48 mobile dust extractors, with or without AUTOCLEAN.
Approved for dust categories L and M: Suitable for use within compatible L and M dust extraction setups.
Stackable Systainer design: Compact, robust and easy to transport with the Festool system.
Flexible operation: The extractor can be used with or without the pre-separator depending on the task.
Extra Information
This is a pre-separator accessory and does not replace the mobile dust extractor itself.
The CT-VA-20 is designed for use with Festool CT 26, CT 36 and CT 48 mobile dust extractors.
It can be used with compatible CT extractors with or without AUTOCLEAN function.
Festool lists the CT-VA-20 as approved for dust categories L and M when used within the correct compatible setup.
The pre-separator is especially useful where the job creates large amounts of dust or chips that would otherwise quickly fill the extractor bag or load the filter.
For best results, use compatible Festool hoses, bags and extraction accessories as part of the full dust extraction system.
Pro Tips
Use the CT-VA-20 for dusty routing, sawing, planing and renovation work where the extractor filter bag fills too quickly.
Check the transparent container regularly so that it is emptied before it becomes overfilled.
Use proper disposal bags when working with fine dust to keep cleanup cleaner and easier.
Keep the connecting hose free from blockages to maintain strong airflow through the system.
For hazardous dust, always make sure the full extractor, filter, bag and safety setup is suitable for the dust class and job.
How to Use
Confirm that the CT-VA-20 is being used with a compatible Festool CT 26, CT 36 or CT 48 mobile dust extractor.
Fit the disposal bag inside the pre-separator collection container if required.
Place the cyclone Systainer and container securely onto the compatible Festool extractor setup.
Connect the supplied connecting hose between the CT-VA-20 and the mobile dust extractor.
Connect the suction hose from the power tool to the CT-VA-20 inlet.
Check that all hose connections are secure and that the container lid is properly fitted.
Start the dust extractor and operate the connected power tool as normal.
Monitor the transparent collection container during use and empty it before it becomes too full.
After use, switch off the extractor, disconnect the hoses and dispose of the collected dust safely.
Clean the container, lid and hose connections as required before storage.

Safety
Wear eye and respiratory protection where the dust type or job requires it.
Always read and follow the manufacturer’s operating and safety instructions for the pre-separator and connected dust extractor.
Use only with compatible Festool CT 26, CT 36 and CT 48 mobile dust extractors.
Make sure all hose connections, the container lid and the extractor connection are secure before use.
Do not use the system for hazardous dust unless the complete extractor, filter, bag and safety setup is rated for that dust class.
Do not extract hot ash, sparks, embers, flammable liquids or ignition sources.
Do not allow the collection container to overfill, as this can reduce performance and increase mess during disposal.
Disconnect the system from the power supply before cleaning, changing bags or carrying out maintenance.
