dryhazardous dustdust

Summary
The 452 AIREX 7V 1/3D is a compact industrial compressed-air vacuum, ATEX Zone 20/22 certified, designed for the safe extraction of combustible dust in sensitive environments (shipyards, electronics industry, confined-space operations).

Functions and use
The unit uses an integrated multi-nozzle venturi technology in a stainless-steel head, providing autonomous (no electrical supply) and maintenance-free suction. It is suited for occasional operations in classified areas and for mobile site work thanks to its compact format and wheeled mobility.

Filtration

• Antistatic polyester pocket filter, category M, offering a large filtering area (20,000 cm²) and resistance to clogging.
• Series HEPA H14 absolute filter, 11,000 cm² surface, capturing 99.995% of particles down to 0.18 µm.
• Manual de-clogging system operated by an external handle to clean filters safely without dispersing dust.

Technical characteristics and operational performance
The machine delivers a high maximum vacuum and an airflow suitable for small interventions in classified areas. It consumes 729 Nl/min at 6 bar (compressed air) and provides a maximum vacuum of 3,700 mmH₂O with an airflow of 150 m³/h. Its detachable 45 L tank eases emptying and handling on site.

Main advantages
