Our FRP Tanks Vacuum Breaker is widely used in water industry. A vacuum breaker typically contains a plastic disc that is pressed forward by water supply pressure, and covers small vent holes. Should the supply pressure drop, the disc springs back opening the vent holes (which let in outside air), and preventing back flow of water.
Our designed Vaccum Breaker, atmospheric vacuum breaker is a device used to prevent back flow, or the reversal of the direction of water against the direction that the system is designed to flow. Back-siphonage occurs when the pressure in a system drops, forcing a higher pressure to fill the difference.
