Air management is critical in wet fire sprinkler system design that utilizes \"Modelmetallic pipe. Trapped air can contribute to corrosion, leading to costly maintenance and potential system failure. NFPA 13 recognizes this and mandates at least a\u00a0single air vent<\/strong> on wet pipe fire sprinkler systems, but the code allows the system designer to determine if additional vents are necessary.<\/span><\/p>\n

8.1.5.1 NFPA 13 (2019) \u2013 \u201cVenting from multiple points on each system shall not be required.\u201d<\/em><\/p>\n

The NFPA 13 Code Requirement<\/strong><\/h3>\n

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.<\/p>\n

Why Choose an Automatic Air Vent?<\/strong><\/h3>\n

<\/p>\n

If you are only installing a single air vent, AGF strongly recommends using an automatic air vent<\/a> to ensure continuous air release even when the system is active. Unlike manual vents requiring intervention every time a system is filled, an automatic vent will expel air throughout the system\u2019s lifecycle, reducing the risk of trapped air pockets contributing to internal pipe corrosion.<\/p>\n

The Unique AGF Automatic Air Vent Design<\/strong><\/h3>\n

AGF\u2019s automatic air vent stands out in the market due to its conical design, which prevents water from becoming trapped above the floats and being expelled when the vent opens. This is a significant advantage over many competitor designs, which often require redundant air vents or drip pans to manage water discharge.<\/p>\n

Additional Features for Optimal Performance<\/strong><\/p>\n

AGF’s automatic air vents come equipped with several additional features that enhance their efficiency and ease of use:<\/p>\n
