The reinforced exhaust screen effectively blocks insects and small pests from entering spaces like attics, workshops, or barns. | Optimized Installation Angles: Features dual-axis adjustability (-45 to +45 horizontal; 0 to 60 vertical tilt) for precise panel orientation. Maximizes energy capture efficiency across diverse roof slopes. | Wildlife Exclusion Design: Equipped with a fine-pitch protective grille to physically block entry by small animals (rodents, birds, squirrels, etc.), preventing wildlife intrusion while ensuring unobstructed fan operation.
