Farr Air Pollution Control (APC), Jonesboro, Ark., says its updated Zephyr® II portable fume and
dust collector offers three-stage filtration and user-friendly, versatile performance. The
self-contained collector captures industrial fumes at their source, and enables periodic dust
collection at various locations within the plant.Three independent filters remove contaminants as
they enter the collector. They include a metal filter to trap sparks, a spunbond polyester main
filter to remove fine particles and a carbon after-filter to remove odors and gases. The main
filter, which is washable, captures 99.99 percent of 0.5-micron and larger particles. Its life is
extended through the use of a reverse pulse cleaning system.
