Abstract
An in-line air purifier (110) for removing contaminants from a compressed air line includes an enclosure (112) having a carrying handle (124), a side wall (116) hinged (118) to a base (114), clasps (120, 122) for releasably closing the side wall (116) onto the base (114), and air inlet (126) and outlet (154, 156) couplers carried on the base (114) for coupling the purifier (110) in a compressed air line. A two stage assembly including replaceable cartridges (40, 42, 90) for removing oil and water, a bed (60) of activated charcoal, and a catalytic bed (76) for carbon monoxide is provided within the base (114) and connected between the inlet (126) and outlet (154, 156) couplers for removing contaminants in compressed air passing therethrough. An air monitor (162) is also provided within the base (114) and connected (157, 158, 160) to the outlet coupler (154, 156) for continuously sampling air passing through the outlet coupler (154, 156). The air monitor (162) includes an indicator (166, 168, 170) for indicating when the concentration of contaminants in air passing through the outlet coupler (154, 156) exceeds a preselected threshold level. The indicator can comprise an audible alarm (168), a light (170), or a digital display (166), or some combination of these.
