Powder and Surface Technology
Clean. Safe. Suitable for surfaces.
In powder and surface coating technology, dust is generated directly during the coating process: during application, color changes, recovery, and cleaning. Controlling this dust is crucial. RUWAC extraction solutions help safely contain powder, ensure surface quality, and guarantee stable coating processes.
Powder coating and coating processes only work under controlled conditions. During powder application, color changes, or in the recovery process, fine particles and overspray are generated, which must be reliably captured without interrupting the coating lines.
At the same time, requirements for occupational safety, explosion protection, and reproducible surface quality are increasing. Even small powder deposits can cause defects, increase rework, or significantly raise cleaning costs.
Therefore, solutions that integrate into existing coating processes, guide powder flows in a controlled manner, and ensure stable production conditions even during operation are crucial.
Control powder flow. Ensure surface quality.
In powder and surface technology, effective powder control directly determines the quality of the coating. Powder is generated where processes actually take place: during application, color changes, recovery, or cleaning of coating systems. If it spreads uncontrollably, it leads to defects, additional cleaning efforts, and unnecessary downtime.
RUWAC extraction solutions ensure that powder is captured directly during the process, safely guided, and separated in a controlled manner. This keeps coating results reproducible, systems clean, and production processes stable and manageable even during frequent color changes.

Technology that efficiently supports color changes and system cleaning.
Manage explosion risks. Integrate safety into the design.
Powder and coating facilities generate fine, often explosive dusts—during powder application, in recovery systems, or when cleaning booths and filters. If these particles are not captured in a controlled manner, dangerous dust concentrations can form and safety requirements can quickly become critical.
RUWAC extraction solutions are designed to address these risks: conductive materials, ATEX-compliant design variants, and safe dust handling within the system. This allows explosion risks to be technically controlled and coating processes to be operated reliably even under safety-critical conditions.

When concepts become part of everyday life.
In powder and surface technology, process quality, workplace safety, and cleanliness must be maintained during normal operations—not as exceptions, but under real-world production conditions. The following examples demonstrate how powder can be controlled, dust safely captured, and coating processes operated reliably even during color changes and maintenance.
Process cleanliness ensures consistent coating results.
During the operation of powder coating systems, powder residues accumulate in booths, extraction areas, and on conveyor systems. If these residues are not removed regularly, color mixing, surface defects, or unplanned cleaning stops can occur. RUWAC industrial vacuum cleaners effectively collect and safely remove powder residues. This ensures that coating processes remain consistent, color changes are manageable, and equipment remains continuously available—even with frequently changing batches and continuous production operations.
Control powder flow. Reduce material loss.
When coating a wide variety of components, residual powder regularly accumulates, especially during frequent color changes. This powder must be collected cleanly and separated so that it can be recycled or disposed of properly. At one company, residual powder is extracted directly from filter boxes and production areas and collected in big bags. This allows for the safe handling of large quantities of powder, reduces material loss, and efficiently supports color changes—even with high throughput and frequently changing coating processes.
Clean air for safe working conditions.
Manual paint application generates paint mist that remains in the painter’s breathing zone and can also settle on equipment and workshop surfaces. Even with modern, low-solvent paints, continuous extraction remains crucial for clean working conditions. In a paint shop, paint mist is captured directly at the source and filtered through multiple stages. This keeps air pollution low, workstations clean, and the painting process safely manageable—even with regular manual application.
Efficiently finishing coating processes.
For powder-coated components, functionally critical holes must be exposed again after coating. Conventional methods such as plugging or masking require additional manual effort before and after coating. At Amahzone plants, the holes are vacuumed directly after the coating process to remove powder residue. This reduces the workload, allows the process to be integrated into continuous production, and enables stable production without additional steps—even in series production involving many components.
The right RUWAC systems for your processes.
Designed for powder and coating processes—and ideal for use in applications where powder must be guided precisely, surface quality must be ensured, and production environments must be kept clean.
Cleaning of coating systems and production environments
Industrial vacuum cleaners remove powder residue from coating booths, conveyor systems, and production areas. They facilitate quick color changes, reduce cleaning efforts, and ensure consistent coating conditions during operation.
Recovery and Handling of Coating Powders
Extraction solutions enable the controlled collection of residual powders directly from processes and filter systems. This helps reduce material loss, safely collect powders, and reuse them cost-effectively.
Extraction of paint mist and fine coating dust
Extraction systems capture paint mist and fine particles directly at the source. This keeps workstations clean, minimizes air pollution, and ensures that coating processes remain consistently controllable.
Industrial cleaning in areas at risk of explosion
Systems designed for the safe handling of explosive powders facilitate regular cleaning in ATEX zones. This helps reduce dust buildup and ensures that safety requirements are reliably met during operation.
Security. From the ground up.
Powder coating and coating processes involve specific risks. Fine powder coatings, as well as metal or plastic dusts, can be explosive, contaminate surfaces, or pose health hazards. At the same time, these hazards arise directly in powder booths, recovery systems, or during plant cleaning—precisely where safety must function reliably during ongoing operations. RUWAC solutions are designed to effectively manage these risks. Depending on the application, ATEX-compliant design variants, conductive materials, suitable filter technologies up to dust class H, and closed disposal systems are utilized. Capture takes place as directly as possible within the process—mobile, process-integrated, or as a central extraction solution. Safety is not an afterthought but an integral part of the technical design—from standards-compliant planning through continuous industrial operation to long-term process and investment security.
Frequently Asked Questions (FAQ)
Coating powders vary greatly in particle size, flow behavior, and explosion parameters. For this reason, each solution is tailored to the specific material, process, and ATEX requirements. It is not the vacuum cleaner alone that matters, but rather the appropriate overall system comprising filtration technology, grounding, dust control, and disposal.
Many systems are modular in design and can be integrated into existing coating lines—as mobile units, partially integrated systems, or fixed process solutions. The specific implementation depends on the booth size, frequency of color changes, and cleaning strategy.
Process-specific extraction reduces powder buildup in booths and around equipment. This helps shorten cleaning times, speed up color changes, and prevent unplanned downtime.
Many powder coatings are classified as explosive dusts. This necessitates compliance with ATEX design variants, grounding concepts, conductive materials, and appropriate filtration technology. The basis for this is always the specific risk assessment for the application.
Whenever powder loss occurs, cleaning efforts increase, or safety requirements become more stringent. A customized solution can reduce color changeover times, make more efficient use of materials, and support stable coating processes.
Let’s talk about your processes.
Powder coating and coating processes must operate reliably on a daily basis—during color changes, cleaning, and ongoing production.
