Delfin 452 AIREX 1/2D-2/2G INERT Industrial Vacuum Cleaner

Compressed Air Powered ATEX Vacuum Cleaner for Reactive and Self-Igniting Metal Dust Recovery

The Delfin 452 AIREX 1/2D-2/2G INERT is a high-performance compressed air powered industrial vacuum cleaner specifically designed for the safe collection of reactive, combustible, and self-igniting metal dusts. Part of Delfin’s specialist INERT range, this ATEX certified industrial vacuum cleaner incorporates an advanced inert fluid bath neutralisation system that safely deactivates hazardous metal dust during collection, significantly reducing the risk of ignition or combustion.

Engineered for applications involving aluminium, titanium, magnesium, and other potentially explosive metal powders, the 452 AIREX INERT achieves a neutralisation efficiency exceeding 95%, providing a safe and compliant solution for hazardous dust recovery in critical industrial environments.

Unlike conventional industrial vacuum cleaners, the 452 AIREX INERT operates entirely using compressed air through a powerful Venturi system, eliminating electrical ignition sources while delivering reliable suction performance for hazardous material recovery.

Suitable for operation in ATEX Zone 21 dust environments and Zone 2 gas environments, with an additional internal ATEX Zone 20 certification providing enhanced protection within the vacuum during combustible dust collection, this specialist industrial vacuum cleaner combines advanced safety technology, powerful pneumatic performance, antistatic filtration, and robust stainless-steel construction to provide a complete solution for reactive metal dust extraction.

For facilities requiring compliant combustible metal dust recovery and explosion prevention systems, this is far more than a standard industrial vacuum cleaner. It is a certified ATEX compressed air vacuum specifically designed for the safe collection and neutralisation of reactive metal dust.
