The PURGENVENT Model 7940BLE Complies with NFPA 13 for Wet Pipe Fire Sprinkler Systems

AGF Manufacturing introduces the PURGENVENT Model 7940BLE, a Build America, Buy America Act (BABAA) compliant automatic air venting valve assembly that increases the longevity and reliability of wet pipe fire sprinkler systems. It helps meet NFPA 13 code requirements while simplifying installation and improving long-term system performance.

NFPA 13 now mandates air venting on all wet pipe fire sprinkler systems that use metallic pipe; the 7940BLE meets this requirement with a UL-listed and FM Approved 7900V automatic air vent that efficiently expels trapped air during normal operation, reducing internal corrosion and the risk of system damage. The conical, recessed design and single-float mechanism ensure precise, protected venting, while an integrated isolation valve and strainer allow for safe maintenance while preventing debris from entering.
