An essential safety feature, a vacuum breaker guards against the potentially harmful consequences of negative pressure or vacuum conditions on tanks, fiberglass/composite pressure vessels, and related pipe systems. By permitting atmospheric air to enter the system when internal pressure falls below ambient levels, it serves as a preventive device that guarantees structural integrity. A vacuum can form when the pressure inside a tank or vessel drops below atmospheric pressure due to system shutdowns, draining, or rapid cooling. This vacuum has the potential to implose, deform, or harm the vessel and any associated pipes if it is not controlled. By immediately introducing air into the system upon detecting a vacuum, our vacuum breakers are made to stop such incidents and successfully balance internal and external pressure.

Key Features

• Prevents vacuum conditions that could lead to tank or piping collapse

• Specifically designed for use with fiberglass/composite pressure vessels

• Allows immediate air entry to equalize pressure when vacuum is detected

• Compact, durable, and corrosion-resistant construction

• Easy installation and minimal maintenance

• Protects against flow disruptions and pump cavitation
