The model AV-6-C4-CMF has 28 inches of Net Free Area (NFA). All 6 inch gravity ventilators come with a standard 9.5 x 9.5 inch curb mount flange.<\/p>\n<h4><strong>Benefits:<\/strong><\/h4>\n<ul>\n<li>Keeps your home comfortable and 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>Installation<\/strong>: For low slope and flat roofs on a <a href=\"https:\/\/roofvents.com\/roof-curbs-all\/\">roof curb<\/a><\/h4>\n<p>This roof vent has a curb mount flange which allows for easy installation on AVP's prefabricated roof curbs. In other words, the flange will fit over <a href=\"https:\/\/roofvents.com\/roof-curbs\/\">roof curbs <\/a>or an existing base with a 9 inch diameter.<\/p>\n<p>6 inch Aura Gravity Vents are compatible with AVP's <a href=\"https:\/\/roofvents.com\/roof-curbs\/roof-curb-fits-6-vent-or-fan-with-cmf-model-rc-6-h6\/\">6 inch tall<\/a> and <a href=\"https:\/\/roofvents.com\/roof-curbs\/roof-curb-fits-6-vent-or-fan-with-cmf-model-rc-6-h12\/\">12 inch tall roof curbs.<\/a><\/p>\n<h4><strong>How it Operates<\/strong>:<\/h4>\n<p><strong>The Aura Gravity Ventilator works like a\u00a0<a href=\"https:\/\/roofvents.com\/2018\/06\/roof-vent-comparison-roof-turbine\/\">roof turbine but with no moving parts<\/a>.<\/strong><\/p>\n<p>Gravity vents rely on the Venturi Effect. This occurs when the wind blows against the outer louvers to create an upward draft. As a result, forcing air to flow out of the vent. Thus, removing heat from the attic in the summer and moisture in the winter. This allows for year-round<a href=\"https:\/\/roofvents.com\/Attic-Ventilation-Flat-Roof\"> ventilation on low slopes or flat roofs<\/a>.<\/p>\n<p>Even the smallest breeze can create exhaust ventilation to draw air out of the gravity vent. Therefore, wind speeds of 11 mph for a 6 inch Gravity Ventilator produces 126 CFM of air exhaust for attic ventilation.<\/p>\n<p>Aura Gravity Vents are <a href=\"https:\/\/roofvents.com\/wp-content\/uploads\/approvals\/Certificate-of-Compliance-Aura-Vent.pdf\">UL Listed<\/a> and rated up to 50+ PSF or wind pressure above 200 MPH.\u00a0 Certified by <a href=\"https:\/\/www.tdi.texas.gov\/wind\/prod\/rv\/rv113.pdf\">Texas Department of Insurance<\/a>, <a href=\"https:\/\/floridabuilding.org\/pr\/pr_app_dtl.aspx?param=wGEVXQwtDqtQ8IrCmLmxstF%2bKwQ7oWHP1DGVbt9AKPQ%3d\">Florida State Approved<\/a> &amp; Conforms to the Standards of <a href=\"https:\/\/roofvents.com\/fire-code\/\">CALFIRE<\/a>.<\/p>\n<p>For any questions, email the sales team at\u00a0<a href=\"mailto:sales@roofvents.com\">sales@roofvents.com<\/a> or call at 845-565-7770.
