The Vevor solar powered fan is designed to improve ventilation in greenhouses, grow tents, chicken coops, shelters, and other enclosed or semi-enclosed spaces. Powered by a 25W solar panel, it operates automatically in sunlight without needing grid power or voltage conversion. It delivers up to 220 CFM airflow with speeds up to 2030 RPM to help move out hot, stale air. The adjustable panel angle and flexible mounting hardware support roof, wall, or vent opening installation. Its tempered glass panel, IP65 rating, and double-layer metal guard make it well suited for hot and humid environments.
