MistBuster® Accessories

MistBuster ducted
The MistBuster® Series offers many solutions for the metalworking industry. Our industrial air cleaning systems capture harmful airborne machining application contaminants by using electrostatic precipitation and media filtration technologies. Machine shops, plants, and other facilities vary in size and available space for an air filtration system. That’s why we’ve designed several different mounting and ducting accessories for the MistBuster® product line. Read on to see the possibilities.


Each mounting solution we provide offers unique benefits. To determine which mounting accessory would best complement your MistBuster®, consider where you plan to install it. We can help determine which mounting strategy works best for your space:

  • Direct mounting – Unit is mounted on top of a machine tool, with no additional ducting or accessories required. We offer an optional two-inch riser to aide in mounting and save space.
  • Pedestal stand – Unit is mounted on an adjustable floor stand and ducted to a machine tool.MistBuster pedestal stand
  • Machine mount stand – Unit is mounted on a machine tool with the stand, which allows for ducting to other sections of the machine tool enclosure.MistBuster machine mount
  • Ceiling mount – Unit is hung from the ceiling.MistBuster ceiling mount MistBuster ceiling mount
  • Wall mount – Attached to the wall using brackets.MistBuster wall mount bracket


An air distribution box called a plenum is used to adapt MistBuster® units to ductwork. Each plenum has a drain at the bottom for connecting a hose through which metalworking fluids can run back into the sump or recollect into the machine tool itself.

All of our plenums are made of powder-coated heavy-gauge steel and work on the MB500, MB Media, MB 850 Compact, and MB850. The MB2000 and MB Infinity are only compatible with the standard plenum. Below is a table outlining the details of each plenum design:
