Hazardous areas · Zone 21 / 22
Where dust can ignite,
we keep vacuuming.
Explosion-proof industrial vacuums for combustible dusts: aluminium, wood, plastics, food powders. Compressed-air or electric drive, dust class M and H, full ATEX documentation included.

Why explosion protection is not an accessory
A standard vacuum is an ignition source in disguise
Motor sparks, static charge in the hose, hot surfaces: a standard industrial vacuum brings several ignition sources into an area where combustible dust is airborne. That is exactly what ATEX zones 21 and 22 are about, and exactly why we engineer dedicated machines instead of retrofitting catalogue models.
Compressed-air line
No electrics on the machine, no motor, no ignition source. First choice for zone 21.
Electric ATEX line
Economical in continuous duty, with explosion-protected drive and filter technology.
Conductive equipment
Grounded hoses, conductive filters and containers against static discharge.
Dust class M / H
Also for hazardous and carcinogenic dusts.
Typical combustible dusts
Aluminium & metal dust
Wood dust & chips
Plastic & granulate dust
Flour, sugar, starch
Toner & pigments
Paper & pulp dust

Frequently asked questions
Which ATEX zones do DEBUS vacuums cover?
Our ATEX series is designed for dust explosion zones 21 and 22. The right configuration depends on your zone classification and the medium. We verify it against your explosion protection document.
Compressed air or electric in hazardous areas?
Compressed-air vacuums have no electric motor and therefore no electrical ignition source, which makes them the most robust choice for zone 21. Electric ATEX vacuums are more economical in continuous operation. We build both lines and advise based on your duty cycle.
What about dust classes M and H?
Dust class (L/M/H) covers filtration performance, the ATEX zone covers explosion risk. They are separate requirements: a vacuum for carcinogenic, combustible dust needs dust class H AND the matching explosion-proof design.
Do you deliver the Ex documentation?
Yes. Every ATEX machine ships with its declaration of conformity and operating documentation for hazardous areas, and we can support integrating it into your explosion protection document.
