Key Features
Overview
Festool 204923 Anti-Static Suction Hose D36/32×3.5m is a conical antistatic dust extraction hose built for Festool dust extractors with Autoclean. This is a suction hose designed for masonry renovation and cleaning work. Model Number: 204923. If you are dealing with abrasive dust, surface prep, or cleanup where airflow and hose handling actually matter, this hose is made for that kind of work.
The big story here is the conical hose design. Festool uses a 32 mm to 36 mm geometry to improve suction performance by reducing restriction through the hose. In plain terms, that means better airflow and better dust pickup, especially when you are pulling heavier debris than fine sawdust. For masonry renovation and cleanup, that is not a small detail. It helps the extractor do its job instead of forcing the tool and vac to fight the hose.
The outer skin is smooth and the hose body is highly flexible, which makes it easier to drag across floors, benches, and jobsite clutter without constantly catching on edges. That sounds simple, but anyone who has used a stiff hose around a grinder or sander knows how much time it wastes when the hose keeps grabbing a corner. Festool clearly built this one to move cleanly behind the tool.
Antistatic construction matters too. Fine dust moving through a hose can build static, especially in dry shop or renovation conditions. This hose is built to reduce that, which helps keep the system more comfortable to use and better suited to dusty work. Festool also lists a bleeder resistor value of less than 1 megaohm per meter, reinforcing that antistatic design.
For tougher environments, the hose is temperature-resistant up to 158 degrees Fahrenheit, and Festool calls it out specifically for masonry renovation and cleaning work. That makes it a better fit for abrasive dust collection than a basic general-purpose vac hose. It is also robust enough to store in a Systainer or inside the dust extractor, which matters if you are packing up daily or moving between service calls and punch-list work.
Compatibility is a real selling point here. The Festool 204923 Anti-Static Suction Hose D36/32×3.5m is suitable for Festool dust extractors with Autoclean, and the rotating adapter includes an RFID chip for automatic suction hose detection on compatible CTM MIDI units. That means the extractor can automatically recognize the hose diameter and adjust accordingly, which saves a setup step and keeps the system working as intended.
This hose makes the most sense for contractors and serious users who already run a Festool dust extractor and need a better hose for masonry dust, renovation cleanup, and heavy dust collection. If you are just looking for a generic replacement hose, this is more specialized than you need. If you already know the value of airflow, smooth handling, and extractor compatibility, this is the right kind of upgrade.
Better Dust Pickup for Heavy Debris
The conical design is not just a shape detail. It is there to help airflow and extraction performance when the hose is connected to an Autoclean-capable Festool dust extractor.
- Conical geometry transitions from 32 mm to 36 mm
- Optimized for Festool dust extractors with Autoclean
- Designed for masonry renovation and cleaning work
Moves Easier Around the Job
Festool gave this hose a smooth outer skin so it glides over edges instead of hanging up every few feet. That makes tool control easier when you are focused on the cut, grind, or cleanup pass.
- Smooth exterior helps prevent snagging on tables, boxes, and corners
- Extremely elastic inner hose improves flexibility
- Works well for active movement around renovation spaces
Made to Work as Part of the System
This is the kind of accessory that makes more sense the more you use your extractor. It stores cleanly, integrates with compatible Festool units, and supports automatic hose detection on select models.
- RFID chip on the rotating adapter supports automatic suction hose detection
- Can fit in a Systainer or inside the dust extractor for transport
- Built for users already invested in the Festool dust extraction platform
