The canister-style Jet dust collector was new for 2003 (the updated link to the web site shows the latest model, which is similar but not identical to mine). It features a 1HP motor, that provides a flow rate of 650 CFM. It has a single 4-inch inlet, which is sufficient for my needs. I only hook up one tool at a time. This model is effectively the same as the older model (DC-650), except that they replaced the cloth bag with an easy-to-replace plastic bag, and, of course, the new canister filter which allows for finer dust collection. The dust collector itself comes in two boxes. This one holds the base (about 68 lbs).
This photo shows the second box, which holds the canister (2-micron) filter, which weighs about 18 lbs. The two brown boxes each hold one 10-foot hose to connect the dust collector to the tools. You'll also see a Y-splitter. This is used to connect the two ports associated with the table saw. The table saw has the normal drop collector below the table, but I have also ordered an overhead arm that will hook up to the other port of the Y-splitter. The overhead arm will capture the dust flying off above the cutting area. The two smaller adapters are for connecting such components as the biscuit joiner and sanders. The 5 metal clamps are for hooking up the 4-inch hoses to the various components.
It took me about 30 minutes to assemble the unit. The instruction manual is very good, plain English, and logically organized. All the parts needed were in the boxes. The unit comes with 5 dust collection plastic bags (the ones that hang down and catch the larger parts). The canister filter catches all the finer dust down to 2 microns. The handle on top of the canister filter is for "rattling" the dust that might otherwise cake up inside the filter.
Here is my set-up ready to go to work.
