If you are vacuuming explosive, impact sensitive or unstable materials that may contain an ignition source, Ruwac’s NA250 immersion separation system will cut risk while keeping your workspace clean. With 30 years of proven performance technology, the NA250 Immersion Separator is designed to work with any existing central vacuum with at least 300 CFM.

The NA250 safely collects explosive or glowing? media particulates entering the vacuum by immediately mixing them in a turbulent liquid bath. It then rapidly forces moving air and liquid to submerge and neutralize all collected particles. The process stops the already contained materials from finding any possible ignition source that could be introduced to the vacuum, guaranteeing a safe working environment and eliminating risk of an explosion.

Utilizing a wet collection seperation system such as the NA250 immersion separator will safely collect and neutralize aluminum, titanium, magnisium, zirconium, mixed metals, sodium azides, TNT, high explosives and other volatile dusts. The importance of a machine that will insure not only the safety of the environment but also that of the employees is priceless.
