Item # Mi-20, Self-Contained Standard Precipitators - 2000 CFM


Self-Contained Standard Precipitators - Model Series: Mi (with Integral Blower/Motor Assembly)- 800 Though 6000 CFM

Mi-series: This product range is self-contained, utilizing its own built in squirrel cage blower and motor assembly. Typically the units are free standing or suspended from the ceiling. Source capture applications use a pickup hose assembly to draw mist or smoke directly from it source and into the precipitator for cleaning much like a vacuum cleaner.
