• Air vents are used to control the air in irrigation systems for proper watering and accurate measurement for flow and water meters.
• Controlling the air in irrigation systems controls the water flow and the most efficient way to control air is by the proper use of air vents.
• Both the presence of air and the absence of air can cause problems and damage to irrigation systems.

Netafim provides air vents to discharge and admit air as required. Trapped air in pipes impedes water flow and can lower watering uniformity. It can also cause water hammer and damage to pipes and fittings. The air in pipes also produces inaccurate readings for water and flow meters. For reliable and accurate water measurement, flow meters require pipes to be full of water. The absence of air in pipes can trigger contaminates such as mud and dirt to be drawn into the piping system.
