Due to the instability of conductive metal dust contained in a confined space along with the fact that the slightest outside ignition source could ignite the already contained dust; Ruwac strongly recommends the use of an immersion separation system for all conductive metals. Sometimes the material is explosive but not the atmosphere. It is not safe for some of these materials to be vacuumed into a dry vacuum.

For these materials, we recommend a Ruwac Immersion Separation System for safe containment.

With an NA-250 or an NA-35, 100% of the intake air is completely submerged in liquid, the chance of an outside ignition source entering the vacuum is safely ruled out.

These materials may include, but are not limited to; aluminum, magnesium, titanium, zirconium, sodium azide, hydrogen, lithium, potassium, rubidium, cesium, francium, & glowing embers, etc.

If the atmosphere is classified as explosive, let us know and we can quote you the correct approved equipment.
