The Altecnic Robocal automated air vent is designed for heating and cooling systems to continuously remove air without manual intervention. It releases air upon system water filling and automatically isolates, preventing water loss, reducing noise, and improving the precision of control valves and overall equipment performance. The automatic air vents operate via a float mechanism, designed for air removal from systems, with a discharge pressure of 6 bar. They are small-sized valves suitable for tight installations, with an optional manual cap and available in compression or male threads. Sizes range from 1/4" to 1/2" or 15mm compression, with check valves available. Installers often encounter customer complaints about system noises indicating air presence.
