Delfin informs about the EN 17348, a new ATEX standard specifically for industrial extraction systems in explosion hazardous areas
🔍 What's inside?
- Clearer zoning classification: New labeling for Zone 20 (indoor areas with explosive dusts).
- HEPA filter requirement: At least two-stage filtration for dust-laden systems.
- Stricter tests and materials: Electrical, mechanical and non-metallic parts must pass special tests (e.g. heat resistance, wear, dust-tightness).
- Inertization requirements: Systems that extract self-igniting or conductive dusts require additional measures - e.g. gas purging.
💡 Why is this important?
Many existing extraction systems comply with the EU Directive 2014/34/EU (ATEX), but do not meet the specific requirements of the new EN 17348. Those working in areas with combustible dusts (e.g., pharmaceuticals, chemicals, food) should take action now – incorrectly classified systems risk explosions, denial of insurance, or regulatory sanctions.
🔧 Practical tips
- Inventory check: Check existing systems for EN 17348 compliance - including two-stage filter systems.
- Safe selection of new systems: When purchasing, look for certified models (Delfin offers suitable solutions).
- Documentation is mandatory: Make sure you have complete certificates and urgently updated operating instructions.
⚠️ Attention!
- Pay attention to the distinction between Zone 20 (interior area) and higher zones.
- If HEPA filters or inerting measures are missing, significant safety risks and liability issues are imminent.
- Insurers can refuse to pay benefits if non-compliance with the standard is established.
