ABSTRACT:
A portable dust collector for woodshop or other use with portable tools has a conic body that is supported on a tripod carriage formed of three legs attaching to gussets at the sides of the conic body. A divider plate within the conic body divides it into a cyclonic chamber between the divider plate and the lower nose, and a fan chamber between the divider plate and a motor plate that closes the upper mouth of the conic body. A final filter cartridge is fitted onto the outlet pipe, so that the dust collector exhausts clean, filtered air into the ambient. The final filter may be supported from a 90-degree elbow, with a removable tray for catching process dust that is knocked off the interior of the filter. The process dust in the cyclone settles into a dust collection barrel supported on a barrel cradle.
