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

Vertical Cartridges!

So how do you over come upward interstitial can velocities without turning the filters on their sides and wasting much of the filter? You cross flow the air into the side of the collector as is done the Farr Gold Series dust collector. This is achieved with a high entry inlet that brings the air into the dust collector at the same height as the cartridges themselves. The air is first sent through a series of staggered channel baffles that distribute the air and also act as a classifier separating out the larger particles and dropping them straight into the hopper without ever seeing the filters. Sparks also have a torturous path and change of direction to make it to the filters. See Figure 2.

This cross flow effect eliminates upward interstitial can velocities. Since the air is brought into the collector at the cartridge level, there is no longer air flowing upward towards the filters. This system combines the benefit of a down flow style air pattern without turning the filters on their sides and wasting a large portion of the media.
