Thanks to a complete redesign of the header, the UFO system eliminates the external chimney and introduces a more compact, stable and functional structure, optimizing airflow and ensuring full ATEX Zone 22 compliance.

Compactness that makes a difference

The innovation stems from the redesign of the electric fan cowl, which allowed the layout of the machine to be radically reorganized.

The external chimney is eliminated, and the entire airflow is handled internally within the structure, reducing the overall height and resulting in a machine that is neater in form and easier to integrate into production spaces. The internal arrangement of components is optimized to increase structural balance and improve overall stability. The downward redistribution of weights lowers the center of gravity, making the machine more stable in use and easier to handle.

When maintenance becomes an operational advantage

One of the most concrete benefits of the new UFO Flow is the simplification of maintenance:
– Direct and quick access to filters and motor
– Elimination of bulky external piping
– Easily removable components
– Reduced response time, with positive impact on production continuity and operating costs

More efficient airflow

The internal air path has been completely redesigned to reduce turbulence and pressure drop, improving operational stability and intake quality.
The result is a more uniform airflow, which enables:
– Improved capture at the source
– Increased efficiency and regularity

Ready for ATEX Zone 22 environments

The new DEDUST PRO series with the UFO Flow header is designed to operate in potentially explosive environments classified as ATEX Zone 22, in accordance with Directive 2014/34/EU.
It is therefore suitable for the extraction of suspended combustible dust that occurs occasionally and for short periods, ensuring maximum safety and reliability in the most sensitive production settings.
The new generation DEDUST PRO with UFO system will be available from February 2026.

This guide delves into:

• Why metal swarf extraction is strategic and what risks are avoided,
• How modern industrial vacuum cleaners work,
• What benefits they bring to production,
• The next innovations in oil and chip extraction.

Why is oil and chip extraction essential in machining?

Any machining process, such as turning, milling, drilling or grinding, produces a lot of metal chips and requires the continuous use of coolant lubricants. During the process, swarf and oil mix, forming a dense compound that is difficult to handle without suitable equipment. When these materials accumulate in machine tool tanks, the space fills up quickly and pumps are likely to get stuck, causing unplanned stoppages and slowdowns for the entire department.

The constant presence of swarf within the coolant also worsens machining quality: if not removed properly, swarf can scratch the workpiece, reduce accuracy and increase scrap. Over time, this mix of dirty oil and metal residue accelerates wear on pumps, tools and internal circuits, resulting in higher maintenance costs.

Another important aspect concerns the durability of coolants. If they are not filtered well, they quickly lose their properties and must be replaced more often, with both economic and environmental impacts. The safety of the work environment is also affected: wet floors, slippery surfaces and scattered residues increase the risk of accidents and make the department less safe.

For all these reasons, equipping oneself with a professional oil and chip vacuum system is no longer just an option, but a necessity for any workshop that wants to maintain high productivity, reduce downtime and ensure quality machining.

How does an industrial vacuum cleaner work?

An industrial chip vacuum is a machine designed to simultaneously vacuum, separate and handle oil and chips. Unlike ordinary vacuum cleaners, these units have dedicated metalworking components and are designed to work continuously. Dupuy solutions, for example, have a professional internal filtration and separation system that simplifies maintenance activities in mechanical departments.

Simultaneous suction of solids and liquids

Dupuy oil and chip vacuums vacuum together:

• metal shavings,
• emulsions,
• cutting oils,
• Sludge and mixed residues.

Once inside, the material is immediately separated to avoid clogging and to ensure orderly handling.

Internal separation of materials

The system is based on three elements:

• Gridded basket
  Holds metal shavings.
• Lower liquid chamber
  Collects filtered oil free of solids.
• Dedicated filters
  Prevent the passage of the smallest impurities. This process makes it possible to work even on large volumes without the risk of overloading or clogging.
• Oil recovery and recycling via booster pumps

Many Dupuy vacuum cleaners include a booster pump that sends the filtered coolant back to the machine tool.
The benefits are immediate:

• Less oil waste,
• Reducing disposal costs,
• Increased process stability,
• Bettertool protection.

This feature makes it possible to talk about sustainable management of cooling lubricants, which is also a very important issue today from an environmental perspective.

Why do industrial vacuum cleaners improve productivity?

The use of industrial vacuum cleaners can significantly increase the productivity of mechanical departments because it ensures a more stable workflow and reduces all those interruptions that often slow down production.

When chips and coolants are removed in a continuous and orderly manner, machine tools work better, without risking clogging or sudden blockages. Workpiece surfaces are cleaner and more precise because scrap does not get trapped in critical areas during machining.

A dedicated oil and swarf suction system also keeps internal tanks cleaner, prolonging pump life and reducing extraordinary maintenance. A tidier and safer working environment, without slippery floors or residue accumulation, improves operator comfort and reduces time lost to urgent cleaning. In addition, recovery of filtered coolants saves on fluid costs and allows operators to work with more consistent quality over time.

All these aspects, added together, make industrial vacuum cleaners a solution that not only optimizes residue management, but also contributes directly to the production continuity and competitiveness of the entire workshop.

Why is it crucial to adjust?

1. Maximum operational safety
   In addition to compliance with ATEX Directive 2014/34/EU, EN17348 marking is now mandatory to ensure protection in high-explosive environments.
2. Clear legal responsibility
   Manufacturers, retailers and users now have an obligation to ensure full compliance with the latest standards.
3. Insurance protection and regulatory compliance
   The use of uncertified devices can lead to serious explosion risks, penalties and loss of insurance coverage.

What does the EN 17348 standard provide for?

• Mandatory double filtration
  → Primary filter (≥95 %) + HEPA H14 (≥99.95 %) for use in zone 20.
• Strictly tested materials
  → Every component (electrical, metallic, nonmetallic) is checked for sparks, electrostatic charges, and overheating.
• Inerting required
  → For conductive powders or those subject to self-ignition.

Strategic complement to EN 17348 for markets outside Europe

In addition to the previous standard, there is IEC 62784, an international standard that defines safety requirements for portable and mobile equipment intended for use in potentially explosive atmospheres, with emphasis on the prevention of ignition by electrical or mechanical components.

Although it is not harmonized with the ATEX Directive, it is a key global reference adopted in many markets outside Europe. It is particularly relevant for manufacturers exporting outside the European Union, as it complements and reinforces criteria already established by European standards, such as EN 17348. The voluntary adoption of IEC 62784 can also increase the level of intrinsic safety of devices, making them more competitive and reliable even in high-risk international settings.

ACD: protection even outside ATEX zones

Even where ATEX regulations do not apply, safety is not an option.
With ACD marking (IEC 60335-2-69:2021), the vacuum cleaners ensure safe performance even in unclassified areas but where potentially explosive dust is present.

Some examples of configuration for these specific areas:

• EN 17348 indoor + ATEX outdoor for mixed environments
• M-class anti-static filters + HEPA H14 for maximum efficiency and safety

The Dupuy range ensures full compliance with regulatory standards for every environment:

✅ ACD models – for unclassified areas

The principle behind the operation of our purification systems is simple but effective: contaminated air enters the dust collector, passes through a stilling chamber where, thanks to gravity, the polluting microparticles precipitate and are separated from the air stream. Thanks to high-efficiency filters and an automatic cleaning system, the dust is blocked and the air is expelled already purified, ensuring a safe working environment.

Particulate matter is one of the major invisible hazards in industrial settings. Inhaled over the long term, they can cause serious damage to health. For this reason, it is essential to have proper extraction systems that can effectively remove them before they come into contact with operators.

The DU-PUY industrial dust collector range welcomes a new product. After Dedust 30 and 50, the Dedust 110 11KW is born. Ideal for the recovery of fine dusts and the suction of chips such as PVC or aluminum, this dust collector can be integrated on existing production plants and configured adapted to customer needs.

A dust collector designed along with the customer

Which needs does the customer have?

The customer produces aluminum shelves with various punctures, on his customer’s directions. To do so, he uses a pantograph with a 10-meters worktop, capable of processing equally long aluminum worktops. The head piercing and processing aluminum produces metal shavings which must be vacuumed in real time to allow aluminum constant and effective processing.
The difficulty of the creation process was the extraction system. In fact, aluminum chips are transported through a very long hose. Therefore, to guarantee the most efficient work surface cleaning at any time, it was essential to evaluate all possible hose and shavings trajectories.

DUPUY solution? The Dedust 110 industrial dust collector

Two 100 mm suction inlets were installed around the boring head to extract the chips directly from the source. These two suction inlets meet at a 150 mm diameter suction hose. So, the hose follows the pantograph head all along the surface. The mobility of the hose is facilitated and safe thanks to a special 10 meters long catenary that allows the hose to move with the head without choking or cutting.
On the other extremity of this suction hose is the new Dedust 110 11KW power dust collector. Thanks to its high airflow, this vacuum cleaner can remove even the largest aluminum chips from the worktop of the Pantograph without even needing to interrupt work processes. The material is then automatically unloaded into big-bags for transfer.

Design, customization and craftsmanship:
the three forces of DUPUY Vacuum Tailor Made

Which are DUPUY Dedust 110 11KW advantages?

The perfect implementation of the vacuum cleaner in the customer’s plant, its easy of use, its totally automated cycle from the suction to the discharge in big-bags makes this dust collector an integrated, practical and powerful product. Thanks to this automatic process, the customer only has to change the big bags when they are full of chips and continue to work the aluminum serenely.
