Why does the Gold Cone work so well? (continued)

The Gold Cone

Now that this fundamental interstitial can velocity issue has been solved with vertical cartridges, a new development in cartridge dust collection has exploded into the industry, dramatically increasing filter life for the end user. This development is the Gold Cone™. What is the Gold Cone? Simply put, it is a cone of pleated filter media that makes a previously unused portion of a dust collector cartridge, useable filter space. See Figure 3.

This is a velocity profile of a traditional cartridge on the inside. Notice a natural "cone" forms of dead air. Farr Patent #5,972,059 describes a revolution in dust collection where this dead space is turned into efficient, useful filtration area. Figure 4 shows the same cartridge now with the Gold Cone concept using this dead air space.
