A grounded FRL for treating a pressurized air supply has a housing with a connecting mechanism for connecting to a collector bowl. The collector bowl is made from a metal base material and has an open end with a connecting mechanism and a closed distal end. The housing has a flange that is electrically conductive and extending downwardly at an exterior of the bowl. At least one grounding clip member is made from electrically conductive material and has an exterior mounting end attached to the flange for electrical connectivity thereto and has a radially inner end that electrically makes contact with the metal base materials of the collector bowl and the housing.
