Abstract:
1. A filter device for substantially minimizing moisture and particulate matter in a stream of compressed air or other fluid including: a housing comprising a first and second body elements, each of the first and second body elements having a closed collar and an open waistband interconnected by a wall, the waistband of each body element having complementary mating components that releasably engage the first and second body elements to form a substantially air/fluid tight internal chamber the first and second body elements include a mounting structure extending from a portion of the respective collar and being centrally located off the chamber; the first body element including an inlet located in a portion of the collar adjacent the mounting structure for ingress of air/fluid from an air/fluid source into the chamber, and the second body element including an outlet located in a portion of the respective collar adjacent the respective mounting structure for egress of air/fluid from the chamber; a paper filter mounted within the internal chamber, the paper filter selected from one or more of a conventional toilet roll or a paper roll having a cylindrical open-ended paper/cardboard core, wherein the ends of the cylindrical core of the paper filter are received on at least a portion of the respective mounting structures, the cylindrical core and mounting structures forming a continuous column structure centrally of the chamber, and wherein a circumferential gap is provided between the inlet and the paper filter to initiate movement of incoming pressurized air/fluid stream about the mounting structure; and wherein in an operating condition, air/fluid, which is directed into the chamber under pressure through the inlet, follows a tortuous air/fluid filter pathway around the column structure and through the paper filter towards the outlet substantially increasing moisture filter efficiency and whereby particulate matter becomes trapped in the paper filter or falls under gravity as the air/fluid stream progresses towards the outlet.
