Protector Vent

Designed for new or existing dry and preaction systems, the oxygen removal vents are the only vent in the industry you can install in the riser room.

The PAV-D/DQ provides automatic gas venting, allowing oxygen-rich gas to be purged from the fire sprinkler system and replaced with high-purity nitrogen gas. The PAV-D/DQ is the only vent in the industry with a failsafe back-pressure regulator, preventing the system from depressurizing below low-pressure alarms or trip pressure. The vent also includes a gas sampling port to measure nitrogen purity using the ECS Handheld Gas Analyzer or the SGA-1 SMART Gas Analyzer.

For use under U.S. Patents 8,720,591, 9,144,700, 9,186,533, and 9,610,466
