When placed in bright, direct sunlight the fan will turn on to ventilate your attic space.<\/p>\n<p>This fan will exhaust air continuously even when there is no sun due to the Venturi Effect. This occurs when the wind blows against the outer louvers to create an upward draft. As a result, allowing air to freely flow out of the vent. <span style=\"display: inline !important;\">In other words, even the smallest breeze can create exhaust ventilation to draw air out of the fan.<\/span><\/p>\n<p>The 1\/8 inch louvers prevent rain, snow, insects, and animals from entering inside the fan.<\/p>\n<p><span style=\"color: #666666; display: inline !important;\">For any questions please see the\u00a0<\/span><a style=\"background-color: #ffffff;\" href=\"https:\/\/roofvents.com\/frequently-asked-questions\/\">frequently asked questions page<\/a><span style=\"color: #666666; display: inline !important;\">.
