<p>A system for extracting small particulate dust from air is provided and uses a two-stage air handling system with a particulate entrapment fluid (125, 169) in the two stages, and a solid cartridge filter medium, the first stage (103) having a cyclone (115) for removing large debris, the second stage (105) having a dispersion chamber (171) nestled inside the top of the first stage (103), wherein air is injected directly into the liquid filter medium (169) through spiral vanes (159) contoured such that the surface of the swirling fluid (169) is made to tumble due to the cascading action. The third stage has a mechanical medium filtration system (107) provided to remove fine particulate matter.</p> |
