The 48 inch Aura Gravity Ventilator with Curb Mount Flange<\/a> is 48 inches in diameter and has a 4 inch tall collar. The model AV-48-C4-CMF has 1,808 inches of Net Free Area (NFA). All 48 inch gravity ventilators come with a standard 52\u2033 x 52\u2033 square curb mount flange.<\/p>\n 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 roof curbs <\/a>or an existing base with a 51 inch diameter.<\/p>\n 48 inch Aura Gravity Vents are compatible with AVP's 12 inch tall<\/a>, and 18 inch tall roof curbs<\/a>.<\/p>\n The Aura Gravity Ventilator works like a\u00a0roof turbine but with no moving parts<\/a>.<\/strong><\/p>\n Gravity vents rely on the Venturi Effect which 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 ventilation on low slopes or flat roofs<\/a>.<\/p>\n Even the smallest breeze can create exhaust ventilation to draw air out of the gravity vent. Therefore, wind speeds of 11 mph for a 48 inch Gravity Ventilator produces 5,711 CFM of air exhaust for attic ventilation.<\/span><\/p>\n Aura Gravity Vents are UL Listed<\/a> and rated up to 50+ PSF or wind pressure above 200 MPH.\u00a0 Certified by Texas Department of Insurance<\/a>, Florida State Approved<\/a> & Conforms to the Standards of CALFIRE<\/a>.<\/p>\n For any questions, email the sales team at\u00a0sales@roofvents.com<\/a> or call at 845-565-7770.
