What Makes This ATEX Certified Industrial Vacuum Different?

Integrated Inert System for Reactive Dust – Neutralises Self-Igniting Metal Dust During Collection

The defining feature of the Zefiro 75 INERT is its advanced inert fluid bath neutralisation system.

As reactive metal dust enters the collection chamber, it is immediately immersed within the inert fluid, significantly reducing the possibility of ignition, combustion or explosive reactions during collection and storage.

The system has been independently tested and achieves neutralisation efficiency greater than 95%, providing an additional level of protection when handling hazardous metal dust.

Suitable for collecting:

Aluminium dust
Titanium dust
Magnesium dust
Other reactive and combustible metal powders

Key benefits include:

Neutralisation efficiency greater than 95%
Independently certified by an accredited third-party body
Specifically developed for reactive and pyrophoric metal dust
Reduces the risk of ignition during collection and disposal
Additional protection beyond standard ATEX certification

For facilities processing reactive metals, inert technology offers a critical safety advantage over conventional industrial vacuum cleaners.

ATEX Zone 22 Certified for Hazardous Dust Environments

The Zefiro 75 INERT is ATEX certified for Zone 22, making it suitable for use in environments where explosive dust atmospheres are not normally present during everyday operation but may occur occasionally. In addition, the vacuum is internally certified for Zone 20, providing an extra level of protection inside the unit where combustible dust is continuously present during operation.

The vacuum also complies with EN IEC 62784:2018 for Zone 22 applications and incorporates numerous safety features designed for hazardous dust collection, including:

Three-phase continuous-duty motor
Integrated safety limiting valve
ATEX-approved components
Robust industrial construction

This certification provides confidence that the vacuum has been engineered specifically for hazardous dust environments while delivering reliable industrial performance.

Advanced Filtration System for Hazardous Dust

The Zefiro 75 INERT features a high-efficiency filtration system designed to maximise dust retention while maintaining excellent airflow.

Filtration features include:

Antistatic polyester M-Class primary filter
Integrated manual filter cleaning system
HEPA filter fitted as standard

The combination of M-Class and HEPA filtration captures both coarse and extremely fine dust particles, helping prevent hazardous contaminants from being released back into the workplace.

For facilities handling combustible metal dust, effective filtration is essential for both operator safety and environmental protection.

Frequently Asked Questions (FAQs)

What is the inert system?

The inert system uses a specialised inert fluid bath to safely neutralise reactive metal dust during collection. This significantly reduces the risk of ignition, combustion and self-heating within the collection container.

What materials can the Zefiro 75 INERT collect?

It is designed specifically for dry dust and solid materials, including reactive metal dust such as aluminium, titanium, magnesium and similar combustible metal powders.

What does ATEX Zone 22 mean?

Zone 22 refers to areas where an explosive dust atmosphere is not normally present during normal operation but may occur occasionally. Equipment used in these environments must be appropriately ATEX certified. The Zefiro 75 INERT also features internal Zone 20 certification, providing additional protection inside the vacuum where combustible dust is present during operation.

Has the neutralisation system been independently tested?

Yes. The inert fluid bath has been independently tested by an accredited third-party body and has demonstrated neutralisation efficiency exceeding 95%.

Is this vacuum suitable for continuous industrial use?

Yes. The Zefiro 75 INERT is equipped with a three-phase motor designed for continuous-duty operation in demanding industrial environments.

Can this vacuum collect liquids?

No. The Zefiro 75 INERT is designed specifically for the collection of dry dust and solid materials.
