ARE YOU UP TO CODE? WE CAN GET YOU THERE. Meet the latest NFPA 13 Standard requirements with the ONLY UL Listed & FM Approved air vent for fire sprinkler systems. To help eliminate corrosion caused by trapped air, the 2016 NFPA 13 has implemented a requirement calling for a single air vent to be installed on each wet sprinkler system. With minimal ongoing maintenance, Potter's Automatic Air Vent (PAV) will reduce trapped air in the system and ensure code compliance. With system venting, water flow alarm response times are improved and cyclic ringing of alarm bells are eliminated, all while protecting against corrosion activity. www.pottersignal.com/PAVhttp://www.pottersignal.com/PAV http://www.pottersignal.com/PAV
