Air management is critical in wet fire sprinkler system design that utilizes
metallic pipe. Trapped air can contribute to corrosion, leading to costly maintenance and potential system failure. NFPA 13 recognizes this and mandates at least a single air vent on wet pipe fire sprinkler systems, but the code allows the system designer to determine if additional vents are necessary.
8.1.5.1 NFPA 13 (2019) – “Venting from multiple points on each system shall not be required.”
The NFPA 13 Code Requirement
NFPA 13 requires at least one air vent near a high point in the system to help exhaust air. However, the code does not specify a maximum number of vents, leaving it up to designers to assess whether additional vents are needed to remove air that causes corrosion. While some manufacturers design vents with redundant air vents or drip pans as a necessity, AGF Manufacturing provides a smarter solution with its innovative automatic air vent design.
