Abstract: A universal drum lid for vacuum systems includes an inlet port configured to intercept downwardly flowing influent at a baffle and engage a direction plate which redirects the flow laterally against an adjacent side wall of the receptacle. An outlet port is shielded by the direction plate. Maximum liquid removal and minimal liquid carryover is achieved through the use of the drum lid. Preferably, a disengagement chamber precedes the baffle for disengaging suspended particles, including liquid, and permitting debris to pass the baffle without blockage. A single float ball-valve is sensitive to flow and will seal the outlet on high liquid entrainment and on high liquid levels.
