Caleffi Automatic High Discharge Air Vent 251003A is used for filling and starting solar heating systems to
discharge even large quantities of air that has formed in the circuits. This function is performed even when there is
considerable pressure thanks to the special geometry of the discharge mechanism, which is identical to the one on
DISCAL 551 series deaerators. The Caleffi 251003A automatic air vent valves has been specifically designed
to work at high temperature with a glycol medium, which is typical of solar heating systems.
