Guardian Air Vents proven design provides more air release capacity than other vents of similar size. Commonly used to break vacuum caused by sytem draining.

Product advantages

• Ensures maximum protection of the irrigation system with proper sizing and placement.

• Ensures vent closure as water fills the system, remains open when air pressure reaches the following:

  • 5 psi for 3/4" and 1" Guardian

  • 10 psi for 2" Guardian

  • 8 psi for 3" Guardian

• Large capacity vents dampen water hammer preventing pipes and fittings from cracking or bursting.

• Made of corrosion-resistant reinforced UV protected composite materials - no metal parts to rust or corrode, no need for spare parts.

• Guardian Air Vent with Shrader Valve is ideal for measuring local line pressure.

Applications

• Commonly used downstream of valves, primarily at manifolds, to break vacuum caused by system draining.

• On sloping terrain to prevent collapsing of pipes caused by vacuum when pipe networks drain.

• Upstream of valves for air discharge during system start-up.
