Festool CLEANTEC CT 15 E HEPA Dust Extractor

Festool CLEANTEC CT 26 HEPA Dust Extractor

Dust-Free Stone Restoration Powerhouse for Shop & Jobsite Pros

When you cut, hone, shape, or polish stone, airborne silica is the invisible profit-killer—slowing teams down with extra cleanup and exposing them to serious health risks.

The Festool CT 26 tackles that problem head-on: high airflow, certified HEPA filtration, and tool-synchronized extraction all packed into a compact, roll-anywhere chassis. The result? Cleaner air, safer crews, and a finish that keeps clients calling you back.

Compact Footprint, Maximum Volume

Most contractors accept that a smaller extractor means more frequent bag changes. Not here. The CT 26’s flat, top-mounted filter lets the entire 26 L / 6.9 gal tub stay free for debris, so gross and net capacity are virtually identical. Less downtime, more production.

Certified HEPA Filtration

A factory-equipped HEPA filter and fully sealed airflow path capture 99.97 % of particles ≥ 0.3 µm, meeting Full-Unit HEPA certification—crucial for OSHA crystalline-silica compliance on stone sites.

Constant High Suction

A compact turbine delivers 138 CFM of airflow and 96 in. of static water lift, so even dense marble slurry or granite dust travels smoothly through the included 11 ½ ft. (3.5 m) smooth-bore antistatic hose. Suction stays steady from start to full bag thanks to Festool’s SELFCLEAN bag design.

Jobsite Mobility & Safety

• Weight: only 37.9 lb, balanced over oversized rear wheels for curb-friendly transport.
  
  
• Locking brake prevents wander on trailers or polished floors.
  
  
• Hose garage + cord wrap keep trip hazards off the slab.
  
  

System Integration for Stone Pros

Instead of juggling multiple vacs, dock your grinder, edge shaper, or polishing system directly to the CT 26:

• SYS-Dock with T-LOC secures Festool Systainers—great for stowing diamond pads or profiling bits next to the extractor.
  
  
• Antistatic hose & sleeve discharge static that can otherwise pit sensitive stone finishes.
  
  
• Bluetooth® or pneumatic remote-start ready—snap-in modules (sold separately) let you fire the vac from a cordless polisher or air-powered router without walking back and forth.

Technical Specifications

Directions for Using CT26

Unbox & Inspect

Remove the unit, hose, SELFCLEAN bag, and HEPA cartridge from the carton. Check that the drum seal is seated and that the locking brake engages crisply.

Install the SELFCLEAN Bag

Lift the lid, slide the hose-side lip of the bag onto the intake stub, and press until locked. The flat-top filter design leaves the full 26 L free for expansion, so the bag can inflate without tearing.

Attach the Smooth Antistatic Hose

Twist-lock the bayonet cuff into the front port—no threads to strip. The smooth exterior glides over stone edges without marring freshly profiled corners.

Dial-In Suction & Tool Sync

Set the rotary dial on your connected grinder or polisher to its extraction port size, then—if you added the Bluetooth® module—pair the vac so it auto-starts when your cordless tool ramps up.

Stow & Go

Wrap the cord around the integrated hooks, nest the hose into the top garage, click your accessory Systainer onto the SYS-Dock, and roll to the next countertop or monument without loose parts.

Routine Maintenance & Filter Life

• Bag swap when suction drops ~15 CFM—thanks to the flat filter you’ll empty nearly the full 24 L of debris first.
  
  
• HEPA cartridge: blow from clean side out with 60 psi air after every fifth bag for peak airflow. Replace annually in heavy-silica environments.
  
  
• Hose care: rinse interior with neutral-pH cleaner to prevent slurry hardening and airflow loss.
  
  

Ideal Stone Restoration Applications

Worktop Fabrication & Edge Profiling

Connect your water-fed router or dry diamond wheel—CFM & static lift keep particulate away from the polish face.

Monument Lettering & On-Site Refinishing

Low weight plus locking brake allow secure setup on uneven cemetery ground without tipping.

Floor Polishing & Honing

Runs effortlessly behind planetary polishers; antistatic hose eliminates shock on metal transition strips.

FAQs

Does the CT 26 ship with everything I need for HEPA compliance?

Yes - it comes with a factory HEPA main filter and a SELFCLEAN disposable bag, so you meet the standard right out of the box.

What hose diameter is included?

A 27 mm → 32 mm tapered smooth-bore hose, 3.5 m (≈ 11 ½ ft) long, perfect for most 5-in. to 7-in. grinders and polishers.

How often will I need to empty the bag when resurfacing 200 sq ft of marble?

Field data shows roughly 8–10 L of dust from a full-grit cycle on that area, so one 24 L-capacity bag comfortably covers the job with margin. (Actual yield varies with stone hardness and initial surface condition.)

Ready for Cleaner, Faster Stone Work?

The Festool CT 26 is more than a vacuum - it’s a productivity multiplier: consistent airflow, OSHA-level filtration, and stone-shop-friendly mobility in one rugged package. Equip your crew with the extractor built to keep pace with grinders, polishers, and profilers all day long - and watch the rework, cleanup, and downtime disappear.
