Weducon’s HEM-70 is the first non-contact cleaning system to offer the narrow web and label industry the same cleaning results as Weducon’s HE series, supplied as the preferred cleaning system by the world’s largest corrugator brand.
Contactless precision cleaning for label / narrow web
The new Weducon HEM-70 non-contact cleaner, developed in close cooperation with the authority on quality optimization for the narrow web and label industry, offers an economically attractive way to maximize cleaning performance and increase quality, printability, and productivity. Thanks to its intelligent design, the HEM-70 system works out of the box and can be seamlessly integrated into any production line.
Benefits of the Weducon HEM-70 non-contact web cleaning system:
- Superior cleaning efficiency: Minimizes laminate inclusions and increases print quality by removing particles up to 0.2 – 2 μm.
- Fewer consumables: Reduces consumables consumption thanks to the effective non-contact cleaning mechanism.
- Improved productivity: Increases throughput and yield by reducing interruptions due to cleaning and maintenance.
Applications of non-contact cleaning in label and narrow web production:
- As a pre-cleaner, before contact cleaning
- For fibrous substrates where contact cleaning is impossible
- If contact cleaning requires excessive consumption of consumables



Key features of Weducon HEM-70 non-contact label and narrow web cleaning system:
- Superior Cleaning Technology: The Weducon HEM-70 features a dynamic, angled entry design that intercepts and removes the debris-loaded boundary air layer. Enhanced by a sophisticated airflow mechanism, this system ensures thorough contaminant removal and capture in its high-efficiency, self-cleaning filter system.
- Advanced Ionization: Active ionization (24 V DC) is located in the heart of the cleaner. The equalization of static charges in the substrate leads to the release of dust particles. This method is utilized rather than the traditional approach, whereby active ionization is placed in front of the cleaner, resulting in some contamination not being removed effectively. By placing the ionizers in the center of the cleaner—in the blower air channel—the clean air flow will blow the ions toward the substrate, significantly enhancing the effectiveness of the discharge process.
- Energy and Operational Cost Efficiency: The system’s design allows up to 30% lower energy consumption than conventional systems. This efficiency extends beyond energy use, contributing to reduced operational noise levels (25 to 30% less than equivalents) and a significant decrease in resource waste, aligning with lean manufacturing principles.
- Sustainability: The HEM-70 non-contact cleaner’s design and production adhere to stringent sustainability standards. From minimizing resource usage in manufacturing to reducing the system’s energy needs during operation, we ensure that our commitment to the environment is evident in every product feature.
- Durable and maintenance-friendly: All key elements are tier-1 quality. For example, the filter housing is made of maintenance-free INOX. The filter/fan unit is self-cleaning utilizing reverse-jet pulse cleaning. Long-life filter cartridges with sub-micron filtration, anti-static coating, ATEX approval, and a life expectancy of at least 60 months. Using high-quality filter medium eliminates the expensive microfiltration cartridges used by traditional suppliers.
Contamination in label and narrow web production – the solution
Dust and microparticles cause major problems in the label and narrow-web printing industry. Contamination leads to printing errors, inclusions in the lamination, ink adhesion problems, waste, material costs and machine downtime.
Based on the needs and challenges of narrow web and label manufacturers, and with the guidance of the expert in cleaning systems for this industry, Weducon developed a new contactless cleaning system: the Weducon HEM-70 series. The HEM-70 is based on our proven HE technology and is a sustainable way for the narrow web and label industry to improve quality and reduce energy consumption, consumables, waste and workload. Moreover, the HEM-70 is an economically attractive solution that quickly pays for itself.
