ACD Industrial Vacuum Cleaners
Safety for environments not classified as ATEX but with combustible dusts
At RGS Vacuum Systems, we are aware that many companies operate in environments where the ATEX directive does not apply and therefore there are no classified areas, but where combustible dusts are still present and pose a real safety risk.That is why we offer a range of ACD-certified vacuum cleaners: solutions designed to vacuum combustible dusts in non-ATEX classified areas guaranteeing high performance and reduced ignition risks.
What does ‘ACD’ mean?
- The EN 60335-2-69 standard defines the requirements for portable, mobile or stationary vacuum cleaners that must handle combustible dust in common environments, i.e. those that are not ATEX certified.
- ACD (Appliances for Combustible Dust) certification requires specific precautions: antistatic filtration, earthing, materials and components tested with IP X4 protection rating to minimise the risk of any possible sparks or ignition sources.
Distinctive features of our ACD vacuum cleaners
In our design, every ACD extractor incorporates:
| Component | Safety function |
| Antistatic filters | Efficiently retain fine dust, reducing the risk of flammable accumulation |
| Integrated grounding system | Electrostatic charges are safely discharged |
| Conductive materials where necessary | Prevent the generation of isolated electrostatic charges |
| Electrical parts | Protected with IP X4 rating, which prevents the ingress of hazardous dust |
| Closed design with secure closures | Prevents dust from escaping into the environment |
Advantages for those who choose ACD vacuum cleaners
- Increased safety: reduced risk of ignition and explosions caused by combustible dust.
- Regulatory compliance: even if ATEX certification is not required, the use of ACD devices helps to comply with current workplace safety regulations.
- Versatile application: ideal for a wide range of sectors such as woodworking, flour processing, paint manufacturing, pharmaceuticals, light metals, 3D printing, etc.
- Operational efficiency: good suction capacity, simplified maintenance, and better protection for the operator and equipment.
- Lower economic investment: compared to Atex versions, while still ensuring operator safety.
When to use an ACD vacuum cleaner instead of an ATEX vacuum cleaner
| Scenario | ACD is sufficient if… | An ATEX extractor is required if… |
| Unclassified area | the environment is not defined as an ATEX Zone by internal regulations or risk assessment | the environment is classified as Zone 22, 21 or 20 for combustible dusts |
| Type of dust | non-conductive or low-reactivity combustible powders, moderate density | Conductive metal dusts, high reactivity, high chemical risk |
| Frequency/Dispersion | occasional or localised operations | constant presence or risk of dust accumulation in enclosed or difficult areas |
Our proposal RGS Vacuum Systems
We offer a line of ACD vacuum cleaners that combines:
- Robust materials and certified components.
- Multi-stage filtration (including HEPA filters where required).
- Wheeled solutions, sizes suitable for small workshops up to industrial production.
- Accessories that aid operational safety: antistatic and reducing dust dispersion accessories, closed containers.
