This is a two stage dust collector for the shop.
To the left is a Super Dust Deputy cyclone filter (Stage 1). The Super Dust Deputy allows the dust to drop into the cardboard cannister.
On the right is a Harbor Freight 2 HP dust collector (Stage 2). The standard bag has been replaced with a better filter from Wynn Environmental, which should filter dust to the .5 micron level.
Most of the dust should settle in the Stage 1 cannister, for easy removal.
Next steps, hook up the equipment and make some dust!
