Oil Mist Eliminators

Oil Mist Eliminators

Visi-Mist®

Visible protection from oil “smoke” and vapors

  • Removes oil mist from vacuum pump exhaust
  • Clear sump provides easy visual inspection of filter condition
  • Coalescing filters require little maintenance
  • Prevents oil residue from settling on walls, floors, furniture, and equipment

When you start a vacuum pump, a cloud of gray “smoke” comes out of the exhaust. That’s a mist of pump fluid. After the pump has been running for a while, you may not see the mist, but it’s still there. If you’ve ever touched a sticky tabletop near a vacuum pump, you know that cleaning up after oil mist is no joke.

An MV VISI-MIST® oil mist eliminator attaches to your pump’s exhaust line, directing the exhaust through a pleated, low-resistance microfiberglass coalescing filter that removes mist before it gets into the room air. The clear styrene sump provides direct inspection of the status of the filter without disassembly.
