R26
Secure. Unload. Reuse.
The dry pre-separator for additive manufacturing: The R26 protects components, recovers valuable metal powder, and makes post-processing faster, cleaner, and more cost-effective—as an intelligent pre-separator positioned before the wet separator.
The R26 is a dry pre-separator for additive manufacturing designed to reliably recover metal powder. It gently separates excess powder before the wet separator, reducing contamination and maintenance requirements. For post-processing operations that minimize powder loss, protect components, and improve cost-effectiveness.

R26 – Certificates

Recover value. Avoid losses.
The R26 moves a crucial step in post-processing to the right place: before the wet separator. Metal powder is separated dry and in a controlled manner before it comes into contact with liquid. This keeps the material clean, free of contaminants, and reusable.
What is lost in many processes remains in the cycle here. Valuable powder fractions are recovered, material yield increases, and the need for new powder decreases. At the same time, the entire workflow stabilizes: consistent powder quality, reproducible results, and post-processing that becomes predictable.
The R26 is therefore not just an accessory, but an economic lever in the additive process—measurable in ROI, noticeable in everyday operations, and relevant for quality, costs, and sustainability.
Powder Cleanly Separated
- The metal powder is separated in a dry state—free of liquid and ready for reprocessing.
Reduce material costs
- Less powder loss means lower costs per build and faster payback.
More stable downstream processes
- Consistent powder quality ensures reproducible results throughout the entire AM workflow.

The R26 reduces the load on downstream systems where it matters most operationally: before the wet separator. The metal powder is separated in a dry state before it comes into contact with liquid. As a result, wet separators stay cleaner, maintenance intervals are extended, and waste volumes are significantly reduced.
The result is not a spectacular effect, but rather quiet, stable operation: less cleaning effort, fewer downtimes, lower costs. The process becomes more predictable—and that is precisely where its strength lies.
Less pollution
- – Very little powder in the wet separator, which means less cleaning and maintenance.
Longer maintenance intervals
- – Clean fluid means longer intervals between service visits.
Lower disposal costs
- – Less contaminated liquid reduces the effort and costs associated with disposal.
Strong in the details.
RUWAC dry pre-separators aren’t just made of high-quality components—they’re built on well-thought-out solutions. From the housing to the control system, every detail is designed for durability, safety, and efficiency. For everyone who relies on reliable technology every day.
Efficient separation. Cleanly executed.
The high-speed cyclone effectively separates metal powder from the air stream before it enters the wet separator. The flow path is designed to ensure that the powder is separated in a controlled manner—without turbulence, without mixing, and without contamination.
The result: dry, separated powder ready for reprocessing, and a wet separator that is subjected to significantly less stress.
Three container sizes. Perfect for the job.

The R26 is available with collection containers in 3.5 L, 7.5 L, or 22.5 L capacities. This allows the volume to be precisely adjusted to the size variant, powder quantity, and process cycle.
Empties safely. Without releasing dust.

The integrated disc valves enable controlled, low-dust discharge of the powder. The container can be closed, replaced, and reinserted without powder escaping into the surrounding area. This protects employees, keeps the work area clean, and makes the discharge process reproducible and safe.
Seamlessly integrable. No system disruption.

The R26 is designed for use in combination with RUWAC wet separators such as the NA7-11, NA7-26, and NA35. It can be permanently mounted or flexibly positioned—depending on the layout and process requirements. This creates a closed, integrated extraction system that logically combines powder recovery, wet separation, and safety.

Frequently Asked Questions (FAQ)
The R26 is used in the post-processing stage of additive manufacturing to extract excess metal powder from components and build chambers and separate it in a dry state before it reaches the wet separator. This ensures that the powder remains reusable while reducing the load on downstream systems.
Yes. The R26 discharges the powder cleanly and dry. It does not come into contact with any liquid and can therefore be recycled and reused—a key factor in cost-effectiveness.
Der R26 reduziert Pulververluste, verkürzt Entpackzeiten und senkt Wartungs- und Entsorgungskosten im Nassabscheider. In Summe amortisiert sich der Einsatz durch Zeitersparnis, geringeren Materialverbrauch und längere Serviceintervalle.
The powder enters the closed system directly rather than being released into the environment. This reduces exposure, dust levels, and risks associated with reactive atmospheres—especially when using aluminum or titanium powders.
The R26 is designed for use with RUWAC NA7, NA11, NA26, and NA35 wet separators. It can be permanently integrated or flexibly installed upstream.
The R26 is available with collection containers in 3.5 L, 7.5 L, and 22.5 L sizes. This allows the volume to be precisely adjusted to the size variant, powder quantity, and process duration.
The fill level can be monitored visually through a sight glass or, optionally, via a sensor. When the tank is full, the suction process is automatically interrupted—ensuring safe, controlled operation.
