The model AV-30-C12 has 706 inches of Net Free Area (NFA). All 30 inch gravity ventilators come with a standard 36\u2033 x 36\u2033 square flange flashing.<\/p>\n<h4><strong>Benefits:<\/strong><\/h4>\n<ul>\n<li>Energy efficient<\/li>\n<li>Inner louvers prevent insects and animals from entering the vent<\/li>\n<li>Round aerodynamic design can withstand harsh weather and wind forces beyond 200 mph<\/li>\n<li>Vent head is removable for easy installation<\/li>\n<li>Noiseless \u2013 does not require electricity to exhaust air<\/li>\n<\/ul>\n<h4><strong>Where to Install<\/strong>:<\/h4>\n<p>Exhaust vents with a collar height of 12 inches are for low slope or flat roof ventilation. However, if installed less than 4 feet from the peak, this roof vent can go on a <a href=\"https:\/\/roofvents.com\/roof-pitch\/\">0\/12 to 5\/12 pitch roof<\/a> in <a href=\"\/exhaust-vent-clearance-for-all-climates\/\">all climate zones.<\/a> See the <a href=\"https:\/\/roofvents.com\/wp-content\/uploads\/products\/instructions\/aura-roof-vent\/pdf\/AV-30-C12-Flat-Roof-Installation-Instructions.pdf\">installation guides<\/a> for help installing.<\/p>\n<p>30 inch diameter roof vents are commercial size, therefore, should be in commercial settings. For those looking to ventilate their homes, please view roof vents with a smaller diameter.<\/p>\n<h4><strong>How it Operates<\/strong>:<\/h4>\n<p><strong>The Aura Gravity Ventilator works like a\u00a0<\/strong><a href=\"https:\/\/roofvents.com\/2018\/06\/roof-vent-comparison-roof-turbine\/\"><strong>roof turbine but with no moving parts<\/strong><\/a><strong>.<\/strong><\/p>\n<p>Aura Gravity Ventilators rely on the Venturi Effect which occurs when the wind blows against the outer louvers. It creates a spinning upward draft through the vent allowing air to dynamically flow out of the vent. Even the smallest breeze can create exhaust ventilation to draw out air from the vent.<\/p>\n<p>The Aura Gravity Roof Vents are made of durable rust-free aluminum. The vent head has a flat one-piece spun lid that prevents rain and snow from entering the vent. The round aerodynamic design can withstand harsh weather and wind forces beyond 200 mph. <span style=\"font-size: 16px; display: inline !important;\">Therefore, wind speeds of 11 mph for a 30 inch Gravity Ventilator produces 1,692 CFM of air exhaust for attic ventilation.<\/span><\/p>\n<p>The inner louvers of the roof vent prevent insects and animals from entering the attic. The louvers also allow the air to flow freely to the outside.<\/p>\n<p>AVP\u2019s Aura Gravity Vents are <a href=\"https:\/\/roofvents.com\/wp-content\/uploads\/approvals\/Certificate-of-Compliance-Aura-Vent.pdf\">UL Listed<\/a>\u00a0and rated up to 50+ PSF or wind pressure above 200 MPH.\u00a0 Certified by\u00a0<a href=\"https:\/\/www.tdi.texas.gov\/wind\/prod\/rv\/rv113.pdf\">Texas Department of Insurance<\/a>,\u00a0<a href=\"https:\/\/floridabuilding.org\/pr\/pr_app_dtl.aspx?param=wGEVXQwtDqtQ8IrCmLmxstF%2bKwQ7oWHP1DGVbt9AKPQ%3d\">Florida State Approved<\/a>\u00a0&amp; Conforms to the Standards of\u00a0<a href=\"https:\/\/roofvents.com\/fire-code\/\">CALFIRE<\/a>.<\/p>\n<p>For any questions please see the\u00a0<a href=\"https:\/\/roofvents.com\/frequently-asked-questions\/\">frequently asked questions page<\/a>.
