Delfin DG50 EXP INERT Industrial Vacuum

ATEX Zone 22 Certified Industrial Vacuum with Inert Technology for Reactive Metal Dust

The Delfin DG50 EXP INERT is a specialist ATEX certified industrial vacuum cleaner designed for the safe collection and neutralisation of reactive and self-igniting metal dust in hazardous environments. Specifically engineered for ATEX Zone 22 applications, this advanced industrial vacuum combines explosion-proof dust extraction with an integrated inert fluid neutralisation system, safely treating combustible metal dust before it enters the collection container.In addition to its external ATEX Zone 22 certification, the vacuum is also internally certified for Zone 20, providing an additional level of protection within the vacuum during the collection of combustible dust.

For manufacturers processing aluminium, titanium, magnesium, and other reactive metals within classified dust explosion risk zones, the DG50 EXP INERT offers one of the most comprehensive safety solutions available. Combining ATEX Zone 22 certification with independently certified inert technology, it provides enhanced protection where conventional industrial vacuum cleaners may not adequately address the hazards associated with reactive metal dust. Its internal Zone 20 certification provides an extra level of protection by recognising that combustible dust may be continuously present inside the vacuum during normal operation.

ATEX Industrial Vacuum for Reactive Metal Dust Applications

The DG50 EXP INERT is purpose-built for industries handling combustible and pyrophoric metal dusts, including:

Foundries
Aerospace manufacturing
Aluminium processing facilities
Titanium machining operations
Magnesium processing plants
Metal fabrication in classified ATEX environments
Industrial manufacturing facilities handling reactive metal dust

In these environments, reactive metal dust presents unique ignition hazards that require more than standard dust extraction. The DG50 EXP INERT actively neutralises collected dust during the extraction process, helping minimise the risk of self-heating, combustion, and ignition while maintaining compliance within classified ATEX Zone 22 areas.

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 DG50 EXP INERT is its advanced inert fluid neutralisation system.

Designed specifically for highly reactive and combustible metal dusts, the system safely treats collected material before it accumulates within the collection container.

Suitable for collecting:

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

Unlike conventional ATEX industrial vacuum cleaners, the DG50 EXP INERT neutralises reactive dust during collection, significantly reducing the risk of ignition within the vacuum.

Key benefits include:

Neutralisation efficiency exceeding 95%
Independently certified by an accredited third-party body
Designed specifically for reactive and self-igniting metal dust
Certified in accordance with UNI EN 17348:2022
Provides additional protection beyond standard ATEX compliance

For facilities processing reactive metals, inert technology provides an essential layer of safety that conventional industrial vacuum cleaners cannot offer.

ATEX Zone 22 Certification for Hazardous Dust Environments

The DG50 EXP INERT is fully ATEX Zone 22 certified, making it suitable for the safe collection of combustible and reactive metal dust in classified dust explosion risk areas. For additional safety, the vacuum is also internally certified for Zone 20, ensuring protection within the collection chamber where combustible dust is continuously present during operation.

What sets this industrial vacuum apart is the combination of its ATEX certification with an independently certified inert neutralisation system. Certified by an accredited third-party body, the inert system achieves a neutralisation efficiency of over 95%, significantly reducing the risk of ignition when collecting self-igniting metal dust.

Powered by a 4.6 kW ATEX-certified three-phase side channel blower, the DG50 EXP INERT delivers powerful, continuous-duty suction while providing the highest levels of protection for hazardous dust applications.

The combination of ATEX Zone 22 certification and third-party certified inert technology makes the DG50 EXP INERT one of the most complete certified solutions available for the safe management of reactive metal dust in classified industrial environments.

Advanced Filtration System for Hazardous Dust

The DG50 EXP INERT incorporates a high-performance filtration system designed to safely contain hazardous dust while maintaining consistent airflow.

Filtration features include:

Antistatic polyester M-Class primary filter
Integrated manual filter cleaning system
HEPA filter fitted as standard
High-efficiency filtration for hazardous dust containment

The HEPA filter ensures exceptionally clean exhaust air by capturing fine particulate matter before air is returned to the workplace.

For facilities handling combustible or reactive dust, efficient filtration is a critical part of maintaining both workplace safety and regulatory compliance.

Frequently Asked Questions (FAQ’s)

What is an inert system?

An inert system uses a specialised neutralising fluid to safely treat reactive metal dust during collection. This helps minimise the risk of self-heating, combustion, and ignition within the collection container.

What types of dust can the DG50 EXP INERT collect?

The vacuum is specifically designed for reactive and combustible metal dusts including aluminium, titanium, magnesium, and other self-igniting metal powders, as well as dry dust and solid materials.

What does ATEX Zone 22 mean?

Zone 22 refers to areas where explosive dust atmospheres are not likely to occur during normal operation but, if they do occur, will only exist for short periods. Equipment used within these areas must comply with ATEX certification requirements. The DG50 EXP INERT also benefits from internal Zone 20 certification, providing an additional level of protection inside the vacuum where combustible dust is present throughout the collection process.

Has the inert system been independently tested?

Yes. The inert neutralisation system has been independently certified by an accredited third-party organisation and achieves neutralisation efficiency greater than 95% in accordance with UNI EN 17348:2022.

Which industries commonly use this vacuum?

Typical applications include aerospace manufacturing, aluminium processing, titanium machining, magnesium processing, light alloy foundries, and industrial facilities handling reactive metal dust within classified ATEX environments.

Can the DG50 EXP INERT collect liquids?

No. The DG50 EXP INERT is designed specifically for the collection of dry dust and solid materials. It is not intended for liquid extraction.
