The Ruwac NA 7 (R07-A) is an industrial wet separator designed for the safe extraction and particle-binding of highly reactive, explosive, or pyrotechnic dusts (such as titanium, aluminum, and magnesium).
Equipped with the R07-A integrated control package, this unit features real-time digital monitoring for differential pressure, vacuum levels, and fluid capacity to prevent hazardous dry startup conditions. Built with a heavy-duty V2A stainless steel tank and Ruwac’s anti-static Glass-Fiber Reinforced Plastic (GRP) housing, it delivers maximum process reliability and worker protection in demanding manufacturing environments.
Key Features & Safety Mechanisms
- Active Wet Separation: Binds volatile and reactive fine particles directly in liquid before reaching vacuum components.
- Integrated Control System (R07-A): Continuously tracks operating parameters, liquid level, differential pressure, vacuum pressure, and operational hours.
- Automated Safety Interlock: Integrated liquid level sensor prevents system startup if fluid levels drop below safe threshold limits.
- Mechanical Safety Flap: Ensures unit operation only occurs when the liquid reservoir is properly seated.
- Electrostatic Dissipation: Equipotential bonding system actively dissipates static charge accumulation.
- Corrosion-Resistant Build: Robust V2A stainless steel construction with easy-to-clean components engineered for repeated sanitation cycles.
