ProtectoRiSE - Anti Shock Air Release and Vacuum Breaker

The ProtectoRiSE is an essential system component. Fitted at the top of rising mains, it prevents airlocks and sudden changes of pressure due to power surges and other causes. The ProtectoRiSE is a three-function double-orifice air valve. It releases air efficiently to prevent pressure build up, allows ingress of air to prevent vacuum in the pipework and provides a controlled bleed of air to maintain system stability.
