Protectoseal Series 7800 Emergency Pressure Vent is designed to provide emergency relief capacity beyond that furnished by the operating vent on tanks. Under normal operating conditions, the vent pallet assembly is closed providing an effective vapor seal. In the event of an emergency (fire involvement of the tank), the pallet lifts in response to the increased pressure in the tank’s vapor space. Vapor is expelled, thereby protecting the tank from dangerous over-pressurization. Pallet assembly automatically closes and reseals when the pressure is reduced.

• Certified flow curves validating flow characteristics of unit
• Certified test report verifying specified settings and leakage performance
• “Air-cushion” pallet design for low leakage performance of no more than 1 SCFH at 90% of the set pressure
• Serialized unit and associated weights for easy identification and traceability Datasheet
