AGF Fire Sprinkler Products - PURGEnVENT by AGF Manufacturing

Starting in 2016, NFPA 13 requires the addition of one air vent on each wet fire sprinkler system that utilizes metallic pipe to help mitigate internal pipe corrosion due to trapped air. Developed with input from sprinkler fitter contractors and fire protection engineers, the AGF patented PURGEnVENT is UL Listed and FM Approved while being the most compact option on the market. Additionally, PURGEnVENT does not require a drain line, drip pan, or redundant air vents to prevent leaks. AGF offers three automatic air vents, Models 7900AAV, 7930ECA, and 7950ILV, and one manual 7910MAV.
