R25
Large quantities. Safely managed. Cleanly handled.
The vacuum cell for large volumes of material: The R25 enables dust-free, safe, and cost-effective filling of big bags—ensuring consistent material flow, reduced emissions, and reliable processes in industrial bulk material handling.
The R25 is a vacuum cell designed for dust-free handling of large quantities of material in big bags. Filling takes place under vacuum pressure without mechanical discharge mechanisms. This reduces wear, dust emissions, and maintenance requirements. For reliable material flows and cost-effective processes when handling powders and bulk materials. And particularly cost-effective for valuable powders or materials where product loss results in costs.

Manage material flows efficiently.
In many industrial processes, large quantities of powder or dust are moved using mechanical discharge systems such as rotary valves or conveyor systems. These systems are prone to wear, require frequent maintenance, and are susceptible to malfunctions—especially when handling poorly flowing or variable materials.
The R25 takes a different approach: Instead of mechanically conveying material, it is transferred into big bags under controlled vacuum pressure. With no moving parts in the product stream, there is less wear, fewer malfunctions, and significantly higher process stability. This makes it easier to organize material flows, reduces maintenance requirements, and sustainably improves plant availability. Even with poorly flowing materials, there are fewer malfunctions caused by bridging or blockages.
The R25 views material handling not as a secondary function of the vacuum system, but as an integral part of stable production processes—where large quantities of material must be moved economically, cleanly, and reliably.
Fewer moving parts, less downtime
- The absence of a mechanical discharge device in the product flow reduces wear and malfunctions.
Preserve material quality
- Vacuum transport without mechanical stress protects sensitive materials.
Increase system availability
- Less maintenance and stable processes, even with difficult materials.
Handling large quantities of powder can quickly lead to dust emissions—especially during discharge, container changes, or at open transfer points. These emissions can contaminate work areas, increase cleaning efforts, and require additional safety measures in sensitive applications.
The R25 operates as a closed vacuum system. The material is conveyed under vacuum pressure and transferred directly into big bags. This keeps dust within the system, minimizes emissions, and keeps work areas clean. At the same time, the closed system improves occupational health and safety and supports compliance with safety-related requirements.
This makes material handling not only more economical but also safer—through controlled dust containment rather than open transfer points.
Closed dust collection system
- – Vacuum pressure prevents dust from escaping during filling and emptying.
Vacuum pressure instead of dust escape
- – Leaks cause air to enter instead of material to exit.
Suitable for sensitive applications
- – Safe handling even with hazardous or explosive dusts.
Strong in the details.
RUWAC industrial vacuum cleaners and system extensions aren’t just made of high-quality components—they’re built on well-thought-out solutions. From the housing to the media routing, every detail is designed to keep processes safe, clean, and under control. For everyone who works with chips, liquids, and demanding conditions on a daily basis.
Open safely. Work safely.
During the suction process, a strong vacuum pressure builds up inside the vacuum cell. For this reason, the R25 is equipped with a safety mechanism that prevents the door from closing unintentionally and protects people from being trapped inside.
The design ensures that operators can work safely at all times—even when changing big bags or performing maintenance. A safety feature that goes largely unnoticed in everyday use but is crucial in an emergency.
Sturdy big-bag seat. Smooth material flow.
The big bag is securely fastened using a sophisticated holding and tensioning system. A dimensionally stable mounting, defined attachment points, and a tight-fitting collar ensure that the material flow is even and controlled.
This prevents wrinkling, improper filling, or dust escape during filling. As a result, the process remains stable—even with large material volumes and long suction cycles.
Vacuum-resistant steel construction. Designed for industrial use.
The R25 features a vacuum-resistant steel construction and is designed for vacuum pressures down to 400 mbar. Its robust design ensures that structural stability is maintained at all times, even under high suction capacities and with large material volumes.
The durable housing protects the process from deformation, leaks, or performance losses. At the same time, it creates a long-lasting process component that operates reliably even under demanding industrial conditions. A design that doesn’t just complement safety—it makes it a prerequisite.
