Efficiently and Effectively Meet NFPA Standards

Wet type dust collectors, or wet scrubbers, are required for the safe collection of combustible metal dust. Wet scrubbers have also been used effectively in many other challenging applications as an alternative to cartridge collectors. Glacier Technology is proud to offer the ProVent Uni-Wash series of wet scrubbers.

  • 50- 30,000 cfm models
  • Efficient up to 3 microns consuming only 3″ wg static pressure
  • Automatic sludge conveyor available
  • Exceeds NFPA #484 for combustible metals

Our wet scrubbers fulfill National Fire Protection Association (NFPA) Standard 484 for the capture of combustible metal dusts created in processes involving aluminum, magnesium, titanium, and zirconium.
