The 5080 Automatic Hygroscopic air vent is commonly used in panel radiators or in high points of a system that have a vertical stand of piping where air frequently gets trapped. If you install this in a horizontal run where less air congregates, the discs will not dry out very often to let air release. This is where float type air vents are a better option. Water pushes the float up sealing the vent. When air fills the vent body, the float is displaced, opening the vent port and allowing air to escape. This is the best option for a part of the system where smaller amounts of air collect out of solution and there is more water than air. There are different types of air vents fro different parts of the system. When they are applied correctly, air will be removed more effectively.
