Vacuum Breakers
Available4 products
Vacuum breakers are used in high-hazard applications where backsiphoning could result in harmful health hazards contaminating the water supply. They have an air inlet that allows air into the system, breaks the vacuum, and prevents backward siphoning into potable water supplies.
Brand
Atmospheric Vacuum Breakers for Steam Service
Atmospheric vacuum breakers are for high-temperature steam applications such as heat exchangers, heating coils, condensate lines, and steam boilers. They operate on the atmospheric vent principle that allows air in to open the valve and break the vacuum to prevent outside water from siphoning back into the system.
