Kitfirealarmresources com System Overview Potter AquaN2 Kit is designed to quickly and effectively exhaust oxygenated air from a wet fire protection system and replace it with high nitrogen gas Reducing the oxygen levels in wet fire protection systems is essential in protecting the system from the effects of oxygen corrosion often found at the air water interface in the fire sprinkler piping the AquaN2 Kit which includes the Nitrogen Injection Manifold NIM and the Quick X Haust Manifold QXM in combination with a Automatic Air Release PAAR B or Potter Air Vent PAV and a nitrogen source can easily remove up to 99.9 of oxygen from a wet Also by removing as much air as possible the fire sprinkler system will have increased performance eliminating delayed activation or activation of vane type waterflow detectors An outline of a typical sprinkler system with AquaN2 Kit installed can be seen in Fig 1 1 Typical AquaN2 System Diagram for use with plastic systems VSR AT INJECTION X HAUST
