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.
