Donaldson Company, Inc.
During normal operation, contaminated air enters the collector through the dirty-air inlet on the bottom of the unit. The air passes
through a reusable first-stage filter designed to collect and coalesce large droplets and particles. Smaller mist droplets pass to a
second-stage filter wrap where the small droplets coalesce into larger droplets.
The third and most efficient stage of filtration is the pleated filter specifically designed to collect, coalesce, and drain fine mist. As
the mist coalesce, the droplets are big enough to run down the element and drain back into the collector. The droplets will drain
on both the inside and outside of the filter cartridge. Liquid that collects on the inside of the cartridge drains back into the machine
center. Clean, mist-free air exits the filter cartridge and discharges near the top of the collector.
Collector Operation
