DISCALAIR solar devices are used in hydronic systems or in the filling and start-up phase of solar heating systems to discharge even large quantities of air that have 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 mechanism on DISCAL Solar 251 series air separators.
