How Did an Italian Company Improve the Cleanliness of Its Paint Booths with DUPUY?
Dust Control in Industrial Paint Booths
In powder coating facilities, keeping the booths clean is essential to ensuring the quality of the process and the safety of the operators.
During the application of the coating, some of the paint particles may remain suspended in the air or settle on interior surfaces, equipment components, and surrounding floors.
The client, an Italian company operating in the industrial painting sector, was faced with managing these accumulations of material inside booths with areas that were difficult to access.
The situation also required special attention due to the ATEX Zone 21 classification of the work environment, where the occasional presence of potentially explosive atmospheres generated by combustible dusts makes it essential to implement appropriate preventive measures.
The goal was to identify a vacuum system capable of effectively collecting debris, simplifying operators’ tasks, and maintaining controlled operating conditions without compromising production continuity.
Key Project Data
40 liters
Residue Collection Capacity
The removable 40-liter container collects paint dust and makes emptying it convenient, minimizing interruptions during cleaning.
20,000 cm²
Filter surface area
These filters help capture fine dust and help maintain adequate suction performance during cleaning operations.
Remove dust buildup without disrupting production
The main challenge faced by the customer involved the presence of paint residue in industrial spray booths. The finest particles tended to gradually settle on surfaces and inside the equipment, making cleaning operations increasingly difficult.
Inadequate dust removal could also cause the dust to become resuspended in the air during normal operations, increasing the risks associated with the presence of combustible dust in an ATEX Zone 21-classified environment.
The operational challenges primarily concerned access to the interior areas of the cabins, the need to prevent residue from spreading during cleaning, and the need to minimize the time spent on maintenance.
For the customer, keeping the booths clean also meant minimizing the risk of contamination between different painting operations, thereby contributing to the quality of the finishes and the proper functioning of the equipment.
Effective cleaning to ensure safety and operational continuity
In an industrial environment classified as ATEX Zone 21, the management of combustible dusts cannot be entrusted to cleaning systems that are not suitable for the characteristics of the area.
Accumulations of material, especially in hard-to-reach areas, posed a critical challenge that required a specific solution capable of removing the residue without causing it to spread into the surrounding environment.
The customer therefore needed an industrial vacuum cleaner that combined three key features: compliance with the area’s ATEX classification, adequate suction performance, and ease of use during daily operations.
The ability to quickly access the various sections of the cabins, collect dust in a controlled manner, and simplify the disposal of the vacuumed material would have allowed operators to manage cleaning operations more effectively.
The implementation of a dedicated solution was therefore an important step toward improving maintenance organization and ensuring that painting activities proceeded smoothly.
DUPUY W2 EX 1/2D: Industrial Dust Collector for Combustible Dusts
To meet the customer’s needs, DUPUY supplied the W2 EX 1/2D industrial vacuum cleaner, a solution designed for collecting combustible dust in industrial environments with potentially explosive atmospheres.
Suitable for use in ATEX Zone 21, the vacuum cleaner combines high suction performance with a compact, mobile design, allowing operators to work directly inside paint booths and in the surrounding areas.
The 1.1 kW brushless motor ensures reliable performance, while the large 20,000 cm² filter surface area promotes effective particle collection. The manual filter cleaning system helps maintain consistent suction performance during use.
The 40-liter collection container, made of AISI 304 stainless steel and easily removable, simplifies the process of emptying and managing waste.
Thanks to its compatibility with various vacuum accessories, the W2 EX 1/2D also allows you to reach even the most hard-to-reach areas of the equipment, adapting to the cabin’s various cleaning needs.
The solution enabled the customer to adopt a more targeted approach to dust management, improving the efficiency of operations and better controlling dust in the work areas.
Cleaner cabins, simplified maintenance, and greater operational efficiency
The introduction of the DUPUY W2 EX 1/2D industrial vacuum cleaner has enabled the customer to improve the management of cleaning operations inside the powder coating booths.
Thanks to the combination of suction performance, mobility, and ergonomic accessories, operators can effectively remove debris even from interior surfaces and hard-to-reach areas, reducing the effort required during operations.
The controlled collection of combustible dust helps limit its resuspension into the environment, thereby helping to maintain operating conditions that comply with the ATEX Zone 21 classification.
More regular and thorough cleaning also helps reduce the risk of contamination between coating operations, thereby ensuring the quality of the finishes and the efficiency of the equipment.
Finally, the greater efficiency of maintenance activities allows production operations to resume more quickly, contributing to process continuity.
The main benefits achieved:
1. Effective removal of residual dust inside booths and in surrounding areas.
2. Improved access to hard-to-reach areas thanks to vacuum accessories.
3. Reduced particle dispersion during cleaning operations.
4. Reduced risk of cross-contamination between different painting operations.
5. Simpler and faster maintenance, supporting production continuity.
The results reported are qualitative in nature: the project does not have documented quantitative data regarding reductions in downtime, maintenance costs, or return on investment.
