Automatic hygroscopic air vent 1/2 inch O15AH

Automatic air vent – removing air from the heating system

This hygroscopic automatic air vent with a diameter of 1/2 inch is a reliable solution for removing air from heating systems. Its operation is based on the use of a hygroscopic disc, which reacts to the presence of air, automatically opening the valve and releasing the accumulated gas. After the air is removed, the valve closes automatically, providing continuous protection against inaccurate system operation. Installation is simple thanks to the standard 1/2 inch BSPP external gas thread.

Construction and principle of operation

The air vent is designed to work in closed systems, including those with a mixture of water and glycol. The key element is a hygroscopic disc made of cellulose fibers. When air appears in the radiator, the disc loses moisture and shrinks, causing the valve to open and release the air. After contact with water, the disc returns to its original size, closing the valve. This method of operation minimizes water loss from the installation and ensures effective air removal without manual intervention.

Application and benefits

• Automation: Eliminates the need to manually bleed radiators, saving time and effort for both installers and end users.
• Efficiency: Maintains optimal heating system performance by removing air, which can cause reduced efficiency and uneven heating.
• Versatility: Suitable for use in various types of heating installations – both in single-family homes, multi-family buildings and commercial facilities.
• Durability: Made of durable materials ensures long-lasting and trouble-free operation.
• Corrosion protection: Removing air reduces the risk of corrosion of heating system components.
• Simple installation: Standard 1/2 inch thread facilitates quick and easy installation in existing installations.
• Hygroscopicity: The hygroscopic disc ensures effective operation even with small amounts of air in the system.

This air vent is a simple but effective solution for anyone who cares about the proper functioning of their heating system. It provides thermal comfort and energy savings by maintaining optimal system performance.
