Vacuum bags

 The correct maintenance of a professional vacuum cleaner depends decisively on the quality of the filter bags used. A high-performance bag ensures efficient retention of fine dust, protects the main filter, maintains constant suction power and extends the life of the equipment. In category vacuum cleaner bags from concris.ro you will find solutions dedicated to intensive use in furniture workshops, renovation sites and technical production.
   

 These bags are essential to prevent the reintroduction of fine particles into the workshop air, to facilitate the safe handling of residues and to comply with the health protection rules of operators exposed to wood dust, MDF, plasterboard or other materials.
   

What characterizes a professional filter bag for technical vacuum cleaners?

Unlike bags for domestic vacuum cleaners, filter bags for professional vacuum cleaners they are designed to withstand high volume coarse or fine dust, allow optimal air flow and integrate technologies that maintain long-term vacuum cleaner performance. The main advantages include:

•  nonwoven fabric (non-woven) of polyester fibres with multi-layer structure (usually 3 layers), resistant to tearing and perforation;
•  SELFCLEAN technology  the bag inflates when the vacuum cleaner is turned on and deflates when it stops, automatically detaching dust deposits from the walls and maintaining a larger free surface for filtration;
•  optimal use of available volume  uniformly distributed dust, without clumps reducing effective capacity;
•  perfect compatibility with Festool models (CTL MINI/MIDI, CT 25, CT 26, CT 36, etc.) and with similar professional vacuum cleaners;
• excellent sealing when mounting, reducing the risk of dust leaks.  

 
In a woodworking shop or intensive sanding, a SELFCLEAN bag significantly reduces the frequency of emptying and keeps vacuuming constant, even after hours of work.

Why choose SELFCLEAN bags over plain paper bags?

• Passive self-cleaning – does not require external AC system; the inflation/deflation effect cleans the bag of each on-off cycle.
• Superior fine dust retention – reduces main filter loading and extends maintenance intervals.
• Hygienic handling – the bag seals easily when removed, minimizing contact with harmful dust (essential to MDF or formaldehyde materials).
• Long-term economy – although the initial price is higher than classic bags, the effective life increases significantly.

 
For coarse dust (sawdust, large scraps), a reusable fabric bag may be an alternative, but for fine dust and medium risk (class M), SELFCLEAN remains the recommended standard.
   

Complementary accessories and correct integration

For maximum performance, combine bags with:

• compatible HEPA or HF main filters;
• antistatic hoses D 27/D 32/D 36;
• watertight connecting sleeves;
• source extraction systems on power tools.

 
Always check the exact compatibility of the bag with your vacuum cleaner model (eg. CT 26 requires SC FIS-CT 26/5). On concris.ro you can also find the complete range of festool accessories compatibles.
   

Important parameters when choosing vacuum cleaner bags

• Model compatibility – CT MINI/MIDI, CT 25, CT 26, CT 36, SYS, etc.
• Nominal volume – 15-25 l for compacts, 26 l or 36 l for large models.
• Material and layers – non-woven polyester ≥3 layers for strength.
• SELFCLEAN – technology essential for fine dust and continuous work.
• Number of pieces/set – sets of 5 are the most economical.
• The presence of discounts – concris.ro often offers 25-33% on packages.

Efficient organization of consumables in the workshop

 
Correct storage of bags (in a dry place, away from moisture) and their preventive replacement (when the bag reaches 70-80% capacity) prevent the vacuum cleaner from falling in performance. Integrate bags into your workflow alongside filters, hoses and accessories – you'll reduce downtime and maintain a clean and healthy work environment.
   

Practical recommendations for the right choice

• For furniture workshop with CTL MIDI or CT 26: SELFCLEAN SC FIS-CT 26/5 – set 5 pcs.
• For site and CT 36: SELFCLEAN SC FIS-CT 36/5 – high volume, high strength.
• For maximum mobility (CT MINI/SYS): SC-FIS-CT MINI or SYS/5.
• Order 5-piece sets – save and always have backup.
