DM AIREX 1/2D-2/2G INERT Industrial Vacuum Cleaner

Compressed Air Powered ATEX Vacuum Cleaner for Hazardous Dust and Explosive Gas Atmospheres

The DM AIREX 1/2D-2/2G INERT is a high-performance compressed air powered industrial vacuum cleaner specifically engineered for the safe recovery of hazardous dusts and solids within ATEX classified environments where both combustible dust and explosive gas atmospheres may be present. Part of Delfin’s specialist INERT range, this ATEX certified industrial vacuum cleaner incorporates an advanced inert fluid bath neutralisation system that safely deactivates reactive dust during collection, significantly reducing the risk of ignition, combustion, or explosion.

Designed to operate within some of the most demanding hazardous environments, the DM AIREX INERT is uniquely certified for both dusty atmospheres (ATEX II 1/2D) and gaseous atmospheres (ATEX II 2G), making it the only certified pneumatic vacuum solution suitable for applications involving the simultaneous presence of combustible dusts and flammable gases. Its ATEX II 1/2D certification provides approval for use in ATEX Zone 21 externally, whilst also offering the additional protection of internal ATEX Zone 20 certification within the collection chamber.

Powered entirely by compressed air through a high-performance Multi Venturi suction unit, available with either 19 or 25 nozzles, the DM AIREX INERT delivers exceptional suction performance while completely eliminating electrical ignition sources. With airflow rates up to 590 m³/h and maximum vacuum levels of 5000 mmH₂O, it provides reliable and continuous operation for hazardous material recovery in critical industrial applications.

Combining advanced inert technology, powerful pneumatic performance, antistatic filtration, and robust industrial construction, the DM AIREX 1/2D-2/2G INERT offers a complete solution for safe dust extraction in high-risk ATEX environments.

For facilities requiring compliant hazardous dust recovery and explosion prevention systems within mixed dust and gas atmospheres, this is far more than a standard industrial vacuum cleaner. It is a specialist ATEX certified compressed air vacuum designed to maximise safety, performance, and regulatory compliance.

Why Choose the DM AIREX 1/2D-2/2G INERT Industrial Vacuum Cleaner?

Advanced Inert Fluid Bath Neutralisation System

The defining feature of the DM AIREX INERT is its integrated inert fluid bath neutralisation system, specifically developed for the safe collection of reactive and potentially hazardous dusts.

As collected material enters the vacuum, it is immediately immersed within the inert fluid bath, helping neutralise reactive particles and significantly reducing the risk of ignition or combustion during collection, storage, and disposal.

Benefits Include:

Safe collection of reactive dusts
Reduced ignition and combustion risks
Enhanced operator safety
Safer maintenance and waste handling procedures
Suitable for hazardous ATEX environments
Performance tested in accordance with EN17348

This advanced safety technology makes the DM AIREX INERT one of the safest industrial vacuum solutions available for hazardous dust management.
