Venting is the term used to describe eliminating air pockets from a system. They can occur, for example, while filling the system during commissioning or after repair work. Analysis has shown that undue care taken during filling can double the water's natural oxygen and nitrogen concentration. On the one hand, this leads to an increased risk of oxygen corrosion; on the other hand, trapped residual air can hinder or entirely block circulation. Since air bubbles collect in high areas, quick air vents are installed in the high parts of a system.  Our air vents reliably assure the automatic elimination of air and other gas pockets in heating, solar and cooling systems preventing flow noises, disruptions to circulation, performance impairment and avoidable
corrosion damage and reducing the need for maintenance.
