Ruwac USA's NA35 Series immersion separator is designed to collect metal additive manufacturing dust.

The company says the NA35 Series is the only immersion separator available on the market featuring a complete self-contained vacuum system.

According to Ruwac, additive manufacturing environments using explosive or impact sensitive materials that may contain an ignition source (such as aluminum, titaniumor zirconium) and other volatile dusts will benefit from eliminating the risk of an explosion, and keep workspaces clean in the process. The NA35 Series collects explosive or glowing media particles entering the vacuum and immediately mixes them in a turbulent liquid bath. From there, moving air and liquid are rapidly forced onto the materials, submerging and neutralizing them in the process in the vacuum’s hydrophobic and oleophobic water filter system. This process stops already contained materials from finding any ignition source that may be introduced into the vacuum, guaranteeing a safe work environment.

Newly designed as part of the NA35 Series is the NA35 HD-110. This immersion separation vacuum features an easy-to-use stainless steel liquid discharge valve located beneath the main housing that acts as the primary source in releasing filtered contents, eliminating any heavy lifting required for emptying. Counter-balanced heavy duty casters and its two-stack design provide portability while the system’s external sight glass acts as the detector of liquid levels.

For the collection of smaller amounts of metal additive manufacturing dust, the CV-NA7 immersion separation vacuum is also available.
