Resideo PV075S Eliminator 319847-401 the MT3025 Extension IO ModuleThe Resideo PV075S Eliminator is a high performance 3 4 inch sweat power vent designed for critical air management in hydronic heating systems. Engineered for efficient microbubble removal, this unit utilizes an internal stainless steel concentric coalescing medium to break surface tension and release trapped air from the system fluid. By maintaining a deaerated system, the PV075S prevents oxygen related corrosion and ensures optimal heat transfer
