- Function: Dust-free filling of big bags under vacuum
- Benefits: Closed material flow without dust emissions
- Application: Powder, dust, and bulk material handling in industrial processes
- System: Used as a pre-separator upstream of RUWAC extraction systems
- Process advantage: No mechanical discharge elements in the product stream
- Safety: Vacuum principle reduces dust escape
- ROI: Less maintenance than mechanical discharge systems

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.
