ATEX Vacuums — Choose Your Zone and Vacuum
Our comprehensive portfolio of ATEX-certified industrial vacuum cleaners, with its own certification, zone classification, filtration system and motor configuration, is divided between three main categories:
ATEX Dust Zones
ATEX Dust Zones include industrial vacuum cleaners designed for areas with combustible dust classified as Zone 21 and Zone 22. This category covers both externally certified ATEX models (2D/3D) and units with internal Zone 20 certification (Da) approved for direct dust recovery in accordance with EN 17348. It explains the difference between self-certified 3D equipment and fully third-party certified Category 1/2D systems, as well as the importance of correct grounding and ESD-safe accessories in ATEX dust environments.

Remaining sub-categories in this ATEX zone classification is:
ATEX Zone 21 – internal Zone 20 (Category 1/2D)
ATEX Combined Zones (Gas / Dust)
ATEX Combined Zones include industrial vacuum cleaners certified for both combustible dust and flammable gases in mixed areas such as Zone 1/21, 2/22 and extended combinations like 1/2/21/22. These machines typically feature external 2GD certification and internal 1GD (Ga/Da) protection, allowing safe recovery of combustible dust even when explosive atmospheres may occur inside the airflow and in the surrounding environment. Based on ATEX 2014/34/EU and EN 17348, this category covers advanced solutions for pharma, chemicals, metal powders, additive manufacturing and cleanrooms.

Remaining sub-categories in this ATEX zone classification is:
ATEX Gas Zone 0 + Dust Zone 21 – internal Zone 20 (Category 1/2GD)
ATEX INERT (Liquid Bath / Metal Powders)
ATEX INERT systems are industrial vacuum cleaners designed for the safe collection of conductive and reactive metal powders such as aluminium, magnesium and titanium. Instead of relying solely on ATEX zone certification, the dust is neutralized inside a liquid bath, eliminating ignition risks caused by sparks or heat. INERT vacuums are essential in additive manufacturing, metal powder handling and high-tech environments where conventional ATEX machines are insufficient. Although used in ATEX areas, INERT solutions form a separate safety category compliant with EN 17348.

ATEX INERT – Zone 1/2/21/22 (Category 2GD)

FAQ – Frequently Asked Questions
Zone 21 and 22 typically require vacuum cleaners certified according to ATEX Directive 2014/34/EU and marked for dust atmospheres (for example categories II 2D or II 3D). The correct model depends on the dust characteristics, minimum ignition energy, conductivity, and both internal and external zone classifications.
Yes, provided the vacuum is certified for dust hazards and built with anti-static components to manage electrostatic discharge. For highly conductive or reactive dusts, additional measures such as inert or wet recovery systems and thorough grounding and bonding are required.
What is the difference between an inert (water immersion) vacuum and an explosion-proof ATEX vacuum?
An ATEX vacuum prevents ignition sources in explosive atmospheres. An inert (water immersion) vacuum neutralises the dust directly in a liquid bath. Inert systems are typically required for reactive or self-heating dusts, where ATEX alone is not sufficient.
Yes. Central and semi-central vacuum systems can be ATEX-certified for dust and gas zones, as long as all components in the airflow path are compliant and the entire installation is designed with proper grounding, bonding and zone separation.
These metal dusts are highly reactive and in some cases self-heating. They should only be vacuumed using systems specifically assessed for combustible metal dusts. In many cases an inert (water immersion) system is required. ATEX vacuums may be used where a risk assessment allows it.
2GD is typically used for equipment suitable for both gas and dust atmospheres in Zones 1 and 21. 3D is used for dust atmospheres in Zone 22. 1/3D often means the internal atmosphere is considered Zone 20 while the exterior is Zone 22. The correct marking depends on zone classification and dust or gas characteristics.
Selection depends on zone classification, dust type, conductivity, particle size and minimum ignition energy, as well as whether dry, wet or inert recovery is required. Proper grounding, bonding and filtration must also be ensured for safe operation.
Yes, but only with equipment specifically designed for combustible or reactive metal powders. Many metal powders require inert recovery. ATEX-certified vacuums may be used in some cases, depending on the risk assessment and powder reactivity.
