The Festool DTS 400 REQ-Plus Delta Orbital Sander + CT 36 EI HEPA Dust Extractor Bundle pairs the Festool DTS 400 REQ-Plus Delta Orbital Sander with the Festool CT 36 EI HEPA Dust Extractor, then adds the Festool Granat Delta Abrasives 100-Piece Value Set Systainer3 and the Festool SELFCLEAN Filter Bags for CT 36, 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 577520-577872-578195-496186.

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 36, 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 36 EI HEPA Dust Extractor

The Festool 577872 CLEANTEC CT 36 EI HEPA Dust Extractor is a professional dust extractor built for workshop dust collection and jobsite cleanup. This is a dust extractor designed for dry and wet extraction, tool-triggered dust collection, and cleaner work around corded and compatible cordless tools. Model Number 577872. If you need one extractor that can handle daily sanding, cutting, drilling, and general cleanup without constantly stopping to empty it, this is the one Festool built to sit right in the middle of your system.

The big selling point here is capacity without the usual penalty in size. Festool gives you a 36-liter container, or nearly 9.5 gallons, while keeping the machine compact enough to move through a shop or around a remodel. That matters when you are collecting dust all day from sanders, track saws, routers, or cleanup work and do not want a small extractor filling up every couple of hours. With up to 138 CFM of airflow and a maximum vacuum rating of 96 inches of static water lift, it has the pull needed for serious dust collection, not just light bench cleanup.

Festool also got the controls right. The touch-style push-button interface is simple to use, and you get five suction levels instead of one fixed setting. That means you can back suction down when a sander wants controlled airflow, or turn it up when you are collecting heavier debris. Tool-triggered operation for corded tools keeps the extractor and tool working together automatically, which is a real time-saver when you are bouncing from cut to cut or moving through repetitive sanding work.

Where this model separates itself from a basic shop vacuum is system integration. The built-in Bluetooth interface lets the extractor start automatically with compatible Festool Bluetooth battery packs or an optional remote control. You can also connect it to the Festool app for support and warning notifications. On the job, that means less walking over to the extractor and less breaking your rhythm. If you already run Festool cordless tools or want cleaner remote startup control, this is a meaningful upgrade over a standard corded extractor.

The physical design is clearly aimed at daily use. The smooth anti-static suction hose is built to reduce snagging, which matters more than it sounds when you are moving around a bench, assembly table, or finished interior. Festool includes integrated hose storage and cord wrap so the setup stays organized instead of turning into a pile of hose and cable at the end of the day. Large wheels make it easier to roll, while the integrated brake keeps it planted once you have it where you want it.

It is also built to function as a hub, not just a vacuum. T-LOC compatibility lets you dock Systainers on top, and Festool also calls out compatibility with the Pre-separator and Workcenter. That gives you one rolling station for extraction, storage, and workflow organization. In a shop, that keeps sanding and cutting accessories together. On a remodel or install job, it cuts down on trips back to the van and helps keep the work area tighter and cleaner.

The included HEPA main filter is a big part of why this extractor matters to pros working indoors, in occupied homes, or anywhere dust control is not optional. Festool rates it for both dry and wet extraction, which adds flexibility when cleanup conditions change during the day. The anti-static setup also helps reduce nuisance static buildup during operation, which makes the overall system feel more refined than a generic jobsite vacuum.

Who should buy it? This extractor makes the most sense for woodworkers, remodelers, finish carpenters, installers, and serious DIY users who already care about cleaner cuts, better sanding results, and less post-job cleanup. If you want the cheapest vacuum possible, this is not that tool. If you want a dust extractor that works like part of a complete Festool workflow and earns its keep every day, the CT 36 EI HEPA is the kind of machine you buy once and use for years.

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 36, 5-Pack

The Festool 496186 SELFCLEAN Filter Bag for CT 36 is a replacement dust extractor bag made for Festool CT 36 units. This is a dust extractor filter bag designed for collecting fine dust and debris while maintaining consistent suction. Model Number: 496186. If you run a CT 36 on sanding, cutting, or general cleanup, this bag matters because it helps the extractor keep working efficiently instead of fading off as the bag fills.

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 36 EI has the largest container of the three, 9.5 gal (36 L), with 138 CFM of airflow for high-volume sanding, sheet goods breakdown and fewer bag changes.
