The 4SEASONS PRO Solar Powered Roof Vent is engineered specifically for sloped roofs and harsh weather environments, delivering powerful, maintenance-free attic ventilation with exceptional durability. Powered entirely by the sun, it removes excess heat, moisture, and humidity from the attic to improve air circulation and help protect your home year-round. Built with a rugged polycarbonate housing, the PRO model is designed to withstand severe weather, including hurricane-force winds, hail, heavy rain, and freezing conditions. Its unique slant-back profile helps reduce wind-driven rain and snow intrusion while directing water away from the vent for added protection. At the heart of the system is a high-efficiency brushless motor, providing smooth, quiet operation. The integrated high-performance monocrystalline solar panel delivers reliable operation from dawn to dusk, even under less-than-ideal sunlight conditions. After sunset, the unit continues to function as a large, weather-resistant passive roof vent. The 4SEASONS PRO is CSA Certified and TAS 100(A) tested for 110 MPH wind-driven rain, making it an excellent choice for regions exposed to severe weather and high-velocity hurricane conditions.
