The Guardian Dynamic Air Vent releases massive volumes of air as your system fills, protecting against water hammer that cracks fittings and splits pipe walls. As pressure builds, the float rises and seals the vent shut, isolating your system from contamination throughout the irrigation cycle. When pressure drops at system shutdown, the float descends instantly, opening the vent to break the vacuum that would otherwise collapse pipes and suck soil into dripperlines. This is transparent protection-working silently and autonomously throughout every irrigation season without maintenance or supervision.\u003c\/p\u003e\n\u003cp\u003eInstallation is intuitive and locations are strategic. Position downstream of control valves at manifolds to break vacuum during system drainage. Use on sloping terrain where natural siphon action creates dangerous suction forces. Place upstream of valves for air discharge during system startup. The composite construction resists corrosion completely-no metal parts to rust, no replacement components to inventory. UV-protective materials withstand harsh seasonal sun exposure. The 2\" Guardian vents at 10 psi air pressure, providing relief capacity appropriate for large-scale irrigation systems. Optional Shrader valve (separate) enables direct pressure measurement at the vent location for advanced system diagnostics and pressure validation.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Capacity Air Release\u003c\/strong\u003e - Discharges large quantities of air through opening equivalent to full-size standard vent.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Hammer Damping\u003c\/strong\u003e - Large-capacity design absorbs pressure surges, preventing pipe and fitting cracks or bursting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic Float Closure\u003c\/strong\u003e - Rises as water enters to seal vent during normal pressurized operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacuum Breaking Mechanism\u003c\/strong\u003e - Float descends when pressure drops, admitting air to prevent pipe collapse and dripper suction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion-Proof Construction\u003c\/strong\u003e - Reinforced UV-protected composite materials; no metal parts to rust or corrode.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo Maintenance Required\u003c\/strong\u003e - Composite design eliminates spare parts inventory and seasonal service protocols.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVent Opening Specification (2\" Guardian)\u003c\/strong\u003e - Opens at 10 psi air pressure for appropriate large-system relief capacity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptional Shrader Valve Port\u003c\/strong\u003e - Enables local line pressure measurement for system diagnostics (valve purchased separately).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible Installation Options\u003c\/strong\u003e - Downstream at manifolds, upstream of valves, or on sloping terrain for comprehensive protection.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Netafim","offers":[{"title":"Default Title","offer_id":56296969732262,"sku":"70561-001735","price":300.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0731\/6344\/0294\/files\/print_65aria2_3-gigapixel-high_fidelity_v2-3x_77bd047c-6a99-4df8-a032-5da161cec760.jpg?v=1773649846","url":"https:\/\/gridfreesupply.com\/products\/netafim-dynamic-air-vent-2-inch-65aridy2","provider":"Grid Free Supply","version":"1.0","type":"link"}
