Demister Filtration Systems

Demister Filtration Unit
To eliminate oil or grease buildup on your roof, our Demister System uses a three-stage process for filtration including velocity reduction and centrifugal separation, water spray scrubbing and demister pad filtration.  First, the air is discharged tangentially down into a larger vessel resulting in lower air speeds, which cause the larger particles to fall out of the exhaust air. The exhaust air is then forced to turn up through the demister vessel, which causes more grease to fall out against the vessel sides and bottom. Second, we use water spray showers in the demister vessel body to “scrub” the airflow of grease and oil. Finally, we have incorporated a specially designed demister filter to capture as much of the remaining grease and oil as possible. There are no moving components in the demister vessel and the filtered material is continuously washed from the vessel by the water flow. These units are self-cleaning and have no moving parts in the air stream. In addition, we can add carbon filter housings to reduce odor emissions.
  • No moving components, easy to maintain and clean
  • 99% efficient for particles 10 micron and greater
  • 75% efficient for 2-3 micron particulate
  • All stainless construction
Water recirculation reduces water consumption and operating costs
