The Guardian Air Vent delivers massive air-release capacity, instantly purging air at system startup while simultaneously preventing water hammer that cracks pipes and shatters fittings. When your system drains, the Guardian opens automatically to admit air and break vacuum-preventing pipe collapse, soil suction into dripperlines, and the downtime costs associated with damaged infrastructure. Your system survives for decades because it breathes.\u003c\/p\u003e\n\u003cp\u003eBuilt from corrosion-resistant, UV-protected composite materials with zero metal parts, the Guardian requires absolutely no maintenance or spare parts replacement. The intelligent float valve opens and closes automatically based on precise pressure thresholds (5 psi for 3\/4\" and 1\", 10 psi for 2\", 8 psi for 3\"), adjusting the venting response to your specific system design. Optional shrader valve allows you to measure line pressure without special equipment.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Function Design\u003c\/strong\u003e - Releases large air volumes at startup and breaks vacuum during draining in one compact unit; prevents water hammer and pipe collapse with proven reliability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic Float Valve Control\u003c\/strong\u003e - Opens when pressure drops below threshold, closes when system pressurizes; zero manual intervention required for optimal operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComposite Construction (No Metal)\u003c\/strong\u003e - Engineered from UV-protected, corrosion-resistant materials; eliminates rust, requires no replacement parts, survives harsh chemicals and extreme weather.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge Capacity Air Displacement\u003c\/strong\u003e - Oversized venting ability compared to equivalent-size competitive vents; ensures rapid air evacuation and faster system pressurization.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptional Shrader Valve\u003c\/strong\u003e - Integrated pressure measurement port allows real-time system diagnostics without cutting lines or installing gauges.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Netafim","offers":[{"title":"1 in. w\/ Shrader Valve - Pack of 24","offer_id":56296964292774,"sku":"70561-004820-PCK","price":1145.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0731\/6344\/0294\/files\/print_65ari075s.jpg?v=1773649804","url":"https:\/\/gridfreesupply.com\/products\/netafim-guardian-air-vacuum-relief-air-vent","provider":"Grid Free Supply","version":"1.0","type":"link"}
