The 18 inch Aura Gravity Ventilator with Curb Mount Flange<\/a> is 18 inches in diameter and has an 8 inch tall collar. The model AV-18-C8-CMF has 200 inches of Net Free Area (NFA). All 18 inch gravity ventilators come with a standard 22\u2033 x 22\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 21 inch diameter.<\/p>\n 18 inch Aura Gravity Vents are compatible with AVP's 6 inch tall<\/a>, 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 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.

How it Operates<\/strong>:<\/h4>\n
Even the smallest breeze can create exhaust ventilation to draw air out of the gravity vent. Therefore, wind speeds of 11 mph for an 18 inch Gravity Ventilator produces 634 CFM of air exhaust for attic ventilation.<\/span><\/h4>\n
