The Festool DTS 400 REQ-Plus Delta Orbital Sander + CT MIDI I HEPA Dust Extractor Bundle pairs the Festool DTS 400 REQ-Plus Delta Orbital Sander with the Festool CT MIDI I HEPA Dust Extractor, then adds the Festool Granat Delta Abrasives 100-Piece Value Set Systainer3 and the Festool SELFCLEAN Filter Bags for CT MIDI I, 5-Pack. This is a sander and HEPA dust extraction bundle designed for dust-free sanding of wood, paint, primer, filler and solid surface. Model number 577520-578512-578195-204308.

Buying the pieces as one system means the setup works on day one. The extractor's anti-static suction hose connects to the DTS 400's dust port, the Granat Delta Abrasives 100-Piece Value Set Systainer3 loads the sander with 100 Granat Delta sheets in five grits, P60 through P220, and the five spare SELFCLEAN bags are sized for the CT MIDI I, so you are not shopping for consumables the first week.

Festool DTS 400 REQ-Plus Delta Orbital Sander

The Festool DTS 400 REQ-Plus Finish Delta Sander is a corded finish sander built for detailed sanding where a larger pad gets in the way. This is a finish delta sander designed for fine sanding small surfaces, edges, and tight corners. Model Number 577520. If you spend your time smoothing window frames, cleaning up inside corners, sanding painted trim, or working on vertical and overhead pieces, this is the kind of sander that earns its spot fast.

What matters most here is control. The delta-shaped pad reaches into places a standard finish sander cannot, and the short 1/16" (2 mm) stroke is aimed at surface quality, not aggressive stock removal. The variable speed range of 6,000 to 12,000 RPM gives you room to slow down for sensitive surfaces or keep the pace up when you are blending edges, sanding veneer, or prepping wood before finish. Festool also uses electronic control to keep power delivery consistent, which helps the scratch pattern stay more even as load changes.

The 250 watt motor gives this sander enough muscle for real finish work without making the tool bulky. Festool specifically positions it as a one-handed sander, and that matters on trim, face frames, narrow parts, and awkward angles where a bigger machine feels clumsy. The compact body, rubberized grip areas, and balanced layout are built to reduce fatigue, especially on vertical panels and overhead work where poor balance shows up quickly in your wrists and shoulders.

For finish sanding, vibration control is not just a comfort feature. It affects how steady you can keep the tool on the surface. Festool's vibration-stop balancing helps the pad stay composed, which makes it easier to maintain full pad contact and avoid uneven pressure near edges. That is a big deal when you are trying to leave a clean surface on painted parts, natural wood, or veneered stock that will show every scratch once finish goes on.

Dust handling is another strong point. The Festool DTS 400 REQ-Plus Finish Delta Sander uses an interlocking dust port that works with Festool CT connectors for a more secure connection during sanding. If you are tied into a dust extractor, you get better dust capture at the source. If you are doing quick punch-list work or working where an extractor is not practical, the included reusable dust bag gives you a cleaner fallback than sanding wide open. Either way, keeping dust under control helps protect the finish, the abrasive, and your work area.

This sander also fits the broader Festool system approach. The interchangeable 4 in x 6 in delta sanding pad works with StickFix style hook and loop abrasives for quick grit changes, and the included protector helps you sand close to adjacent surfaces without beating them up. The Plug-it detachable cord is another practical detail on the jobsite. It makes storage easier, simplifies cord replacement, and fits the way many shops and crews already work with Festool corded tools.

Who should buy it? Finish carpenters, cabinet installers, painters doing prep work, remodelers, and woodworkers who regularly sand corners, profiles, frames, and edge-heavy parts. Serious DIY users will appreciate it too, but this is not a cheap throwaway detail sander. It is for people who care about finish quality, cleaner sanding, and better control in tight spaces. If most of your sanding happens on broad flat panels, a larger finish sander may make more sense. If your work lives around corners, trim, and detail surfaces, this is the right shape for the job.

Festool CT MIDI I HEPA Dust Extractor

Festool 578512 CT MIDI I HEPA Bluetooth Dust Extractor is a compact mobile dust extractor built for contractors, installers, finish carpenters, and serious DIY users who need clean work with less hassle. This is a dust extractor designed for on-site dust collection, cleanup, and tool-connected extraction during sanding, routing, sawing, and drilling. Model Number: 578512. If you want a unit that is easy to move but still has the suction and control features that matter on real jobs, this is the lane the CT MIDI I is built for.

The big reason this extractor stands out is how much performance Festool fits into a small platform. With up to 130 CFM of airflow and a maximum vacuum rating of 96 in static water lift, it is built to keep up with common power tool dust collection tasks and final cleanup without feeling underpowered. The suction is adjustable in five levels, which matters when you are switching between tasks like sanding a painted door, trimming material indoors, or drilling where too much suction can fight the tool.

Festool also got the day-to-day usability right here. The touch controls are simple and easy to use, even when you are wearing gloves or working in dusty conditions. The smooth tapered suction hose is designed to reduce snagging, which is a small detail until you are dragging a hose around finished flooring, around sawhorses, or along a guide rail all day. The flat top gives you a usable storage surface, and the integrated hose garage and cord wrap keep the setup from turning into a pile of hose and cable in the van.

Filter access is another practical improvement. The main filter can be replaced from the outside, and the manual filter cleaning function helps restore airflow when the filter or bag starts to load up. In plain terms, that means you can keep suction where it needs to be and use more of the bag capacity before stopping. For anyone doing repeated sanding or punch-list work inside occupied spaces, that is a real time-saver.

Dust control is only half the story. The CT MIDI I HEPA is also set up to work smarter with your tools. The built-in electrical outlet supports tool-triggered auto-on operation for corded tools, so the extractor starts with the tool instead of forcing you to make a second trip. Integrated Bluetooth expands that to certain cordless setups when used with Bluetooth battery packs or an optional remote control. That makes this extractor a better fit for mixed corded and cordless workflows than a basic shop vacuum.

On portability, this unit lands in a very useful middle ground. It is lighter and easier to carry than a larger extractor, but it still gives you a 4.0 gallon container capacity and 3.3 gallon filter bag capacity. The chassis is built for jobsite movement, with large rear wheels, front casters, and a locking brake to keep it planted once you have it where you need it. Festool also integrates the extractor with its Systainer system through the T-LOC connection, which matters if your workflow already revolves around stacked tool storage and mobile setups.

The wet extraction capability adds flexibility, but there is an important detail: wet extraction requires a special wet filter. The built-in LevelStop system shuts the motor down when collecting water to help protect the machine. That makes this more versatile than a dust-only extractor, but it is still clearly optimized for clean, mobile dust extraction around power tools first.

Who should buy it? If you work inside finished spaces, do installation work, punch-list work, cabinet fitting, trim, door prep, flooring, or light remodeling, this Festool dust extractor makes a lot of sense. It is especially good for users who care about mobility, cleaner indoor work, and better integration with cordless and corded tools. If you need maximum debris capacity for heavy demolition, you would step up in size. If you want a compact extractor that travels well and does the job right, this one is right in the sweet spot.

Festool Granat Delta Abrasives 100-Piece Value Set Systainer3

The Festool 578195 Granat DTS/DTSC 400 Delta Abrasives 100-Piece Value Set Systainer3 is a delta sanding abrasive assortment packed in a SYS3 M 112 Systainer for organized storage and transport. This is a delta sanding disc set designed for detail sanding, finish prep, and surface preparation on paints, hard substrates, fillers, plastics, acrylic, and similar materials. Model Number: 578195. If you already run a Festool delta sander, this set gives you a full working range of grits in one box instead of piecing sheets together one sleeve at a time.

What makes this set useful is the spread of grits. Festool includes 20 Granat STF DELTA/9 abrasives each in P60, P80, P120, P180, and P220. That means you can start with heavier material removal when needed, then step through the sequence for surface prep and final sanding without changing systems or digging through loose packs. For painters, finish carpenters, and woodworkers, that matters because detail sanding usually happens at edges, profiles, corners, and patch areas where changing grits quickly keeps the job moving.

Festool SELFCLEAN Filter Bags for CT MIDI I, 5-Pack

The Festool 204308 Self-Cleaning Filter Bags For CT 15 / CT MINI I / CT MIDI I, 5-Pack is a replacement dust extractor filter bag set for select Festool vacuums. This is a dust bag designed for collecting and containing dust and debris during cleanup, sanding, and general extraction work. Model Number 204308. If you use a Festool CT 15, CT MINI I, CT MIDI I, or compatible CTC MINI/MIDI extractor, these bags matter because they help maintain suction while making disposal cleaner and faster.

Who should buy this bundle? Finishers, cabinetmakers, painters and remodelers who sand indoors and want the dust in the bag, not on the floor or in the air. The CT MIDI I is the most compact and portable of the three extractor options, with a 4.0 gal container and 130 CFM of airflow, a good fit for installers who carry the extractor room to room and in and out of the van.
