In the industrial dust collection business, a "gold cone" refers to a unique filter cartridge manufactured by Farr Air Pollution Control in Jonesboro, AR. It refers to an inner cone of filter media within the outer, cylindrical pleat pack. This inner cone of media provides expanded capacity, uniform dispersion of back-pulsed air and opens up more usable space for airflow in the dust collector.This additional use of wide-spaced media pleats also permits collected dust to be dislodged easier from between the pleats during the cleaning cycle, unlike typical industry packed media pleats. The Gold Cone® media has the same filtration efficiency as the outer media pack at 99.999% separation efficiency down to 0.5 micron by weight.
