ATEX Zone 22 Certified Explosion Proof Vacuum Cleaner

The Delfin 452 AIREX 1/3D carries the ATEX marking:
II 1/3D Ex h tb IIIC Dc

This certification confirms suitability for use in:

External ATEX Zone 22 environments
Internal ATEX Zone 20 areas within the vacuum

Designed and manufactured in accordance with ATEX EN 17348 requirements, the vacuum provides safe and compliant operation in environments where combustible dusts may create potentially explosive atmospheres. While the vacuum is designed for use in Zone 22 classified work areas, the internally certified Zone 20 construction enhances safety by protecting against explosive dust atmospheres that may exist within the collection container during operation.

All accessories, flexible hoses, and non-metallic components are tested for spark resistance and static-dissipative properties to further reduce ignition risks during operation.

The vacuum is fully compliant with:

ATEX EN 17348
EN 17348:2022
