Additive Manufacturing

Product Overview

Ruwac is the #1 provider of explosion proof vacuums worldwide for additive manufacturing, and has over 30 years experience manufacturing immersion vacuums. With proven performance and its “safety has no compromise” mentality, Ruwac understands that one of the biggest hurdles an evolving additive manufacturing faces is the by-product of dust. With the nature of the materials becoming more exotic and changing rapidly, it’s critical to clearly identify the specific hazard that applies to the kind of dust you are working with. According to a 2008 study by the Combustible Dust Policy Institute, metal and plastics combined for nearly 40% of the 200+ combustible dust-related fires and explosions in all major sectors during that year, proving that many are either unaware or ignoring the dangers their materials pose.

Metal Dusts

For metal dusts, neutralizing 100% of the intake air and material in an immersion separation vacuum’s liquid bath eliminates the hazard of an ignition source ever reaching the combustible dust. Due to the fact that combustible metals are so volatile, the smallest amount of static could ignite the smallest amount of material and resulting in a violent explosion. Wet systems capture and submerge the material in either an oil or water bath. The pressure of the material that enters the vacuum penetrates the turbulent liquid, quenching any possible ignition source. Special dispersion screens and demisting filters are used to eliminate any moisture from escaping the vacuum system. These filters return only clean dry air into the workplace.

Plastic Dusts

Plastic dust produced during the 3-D printing process can create an equally dangerous environment. This application however won’t require an immersion system, but instead can be removed using a dry vacuum. The FRV110 Explosion Proof  Vacuum is your certified explosion proof solution designed to collect and containing very fine combustible dusts like plastics. Whether it’s heavy pickup in and around production equipment and storage areas or performing light general housekeeping around your plant, the exceptional cleaning power, durability and safety of Ruwac’s FRV110 Explosion Proof Vacuum has made it the vacuum of choice for dry, fine combustible plastic dust everywhere!

  • ETL Certified to UL and CSA standards for Class I, Div 1, 2, Group D and Class II, Div 1, 2, Group F & G dust environments
  • Carbon impregnated housing is chemically neutral and static dissipating to eliminate static discharge
  • Explosion proof TEFC motor rated for continuous duty operation
  • Virtually indestructible housing will never dent or rust, is fully modular to accommodate filter upgrades and is backed by Ruwac’s lifetime warranty
