Vacuum Breakers

Vacuum breakers are designed to introduce air into piping systems, tanks and process equipment when vacuum conditions occur. This helps prevent siphoning, protects tanks from collapse and reduces the risk of equipment damage caused by negative pressure. Watercare Products supplies industrial vacuum breakers in Singapore for water treatment, chemical processing, storage tanks and general fluid-handling applications. Our range includes corrosion-resistant Plast-O-Matic vacuum breakers designed for dependable operation with water, chemicals and other compatible process fluids. Plast-O-Matic Series VBM vacuum breakers use a normally closed, patented self-sealing diaphragm design with only one moving part for simple and reliable operation. Series VBS models use a corrosion-resistant PFA-encapsulated spring acting on a poppet seat designed to minimise sticking and chatter. Vacuum breakers can be installed on piping systems to help prevent siphoning or on tanks and vessels to admit air when internal pressure falls below atmospheric pressure.
