The NA250 is a wet separator designed for large volumes of reactive or explosive dusts. A large liquid volume and efficient wetting ensure high safety and long service life. Forced ventilation further enhances operational safety. For safety-critical applications involving high dust generation and demanding processes.

The highlights.

75 l liquid capacity: longer operating intervals, high intake capacity and fewer liquid changes.

Immediate wetting at the inlet: the immersion tube and turbulence screen provide almost complete particle capture, including sparks and abrasive grinding particles.

Controlled gas venting: self-opening ventilation safely releases hydrogen generated in the process.

Easy to empty and clean: a design that opens on all sides allows quick liquid changes and easy access.

Optional M/H residual dust filtration: additional protection where required.

Large capacity. High security. Ample reserve.

The NA250 is the wet separator for processes where safety margins are critical.
With a liquid capacity of 75 liters, it reliably captures reactive, explosive, or pyrotechnic dusts and significantly extends service life.

Sparks, hot grinding particles, or abrasive media are immediately submerged in liquid and wetted. This mitigates risks early on—before they can damage filters, equipment, or processes.
The result is stable operations, predictable maintenance intervals, and a high degree of process reliability, even with demanding materials.

More reserve, fewer interruptions

Large capacity for long operating times with continuous material feed.

Safety Through Binding

The material being sucked up is passed directly under the liquid and neutralized in a controlled manner.

Stable with critical media

For pyrotechnics, additive manufacturing, metalworking, and specialty processes.

Greater safety before things get critical.

The NA250 operates where risks arise: upstream of the vacuum cleaner. As a wet separator, it captures and neutralizes hazardous dust before it reaches filters, components, or equipment.

This makes it a preventive safety component in the system—not a reaction, but a proactive measure. Processes remain stable, filters are relieved of load, and the service life of downstream equipment is extended.

Neutralized before the filter

– Provides long-lasting relief for the suction unit and filter.

Passive, but effective

– No self-contained drive system; easy to integrate.

Grows with the process

– Can be used temporarily, permanently, or as an upgrade.

Thinking ahead.

At RUWAC, it all starts with a simple question: What do you really need?

Whether it’s a standard model, a modular design, or a custom-built system—we don’t build for the average, but for specific applications. For your processes. Your requirements. Your safety. We make what’s technically feasible a reality. And what doesn’t exist yet, we develop—together with you.

Because when it comes to industrial extraction, we never settle for standard solutions. Only for the best solution.

Strong in the details.

RUWAC wet 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.

Mehr Volumen. Mehr Kontrolle.

With a liquid capacity of 75 litres, the NA250 offers substantially greater reserves than smaller wet separators. Reactive or explosive dusts are captured directly in liquid to control their hazards. The large capacity supports long operating periods, reduces change frequency and improves process stability, particularly with continuous or highly variable material input. An integrated sight glass allows the fill level to be checked at any time.

Capturing sparks before they become a hazard.

The immersion tube, turbulence screen and demister form a coordinated system in the NA250. Collected material is directed below the liquid surface, air bubbles are broken up and fine droplets are separated. This controls dust, hot particles, sparks and abrasive grinding residues before they reach downstream components. The result is almost complete wetting and a high level of process safety.

Capturing reactive materials can generate hydrogen. The NA250 accounts for this in its design: a self-opening valve provides controlled venting of the gases produced and prevents excessive pressure or gas accumulation in the system. This protective function is integrated into the design.

Straightforward maintenance and draining.

Despite its size, the NA250 is easy to maintain. A design that opens on all sides, smooth surfaces and accessible components simplify cleaning and service. An integrated outlet with a ball valve allows controlled draining without moving or dismantling the separator. This saves time, reduces exposure and keeps routine work clean.
