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
- Modular design makes the unit easier to disassemble and clean
- Element replacement is fast and easy
- Water or refrigerant cooling option is available
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.
