Purchased this to upgrade from the standard bag filter on a 15+ year old Jet DC-650. It was easy to install and exceeded my expectations in terms of performance. I've a ~40' U-shaped set of 4" ducting around the outer walls of my small shop. The DC-650 is connected to the "base" of the U. There are flexible drops to each tool and blast gates situated so I can use one leg of the U and one tool at a time. Before the upgrade it worked reasonably but suction was just okay and the bag let fine dust out into the air. After the upgrade, the suction strength increased notably. In fact, the first time I turned it on, I could hear chips that had previously, apparently, been stuck in the ducting travel to the collector. You can also easily feel/hear the increased suction at the tools. There is also less fine dust in the air. I wish I would have upgraded sooner.
