35W Solar Attic Fan, 2200 CFM Smart Roof Vent Built-in Temperature Sensors(JBSF-320E)

Intelligent Solar-AC Hybrid Mode – The newly enhanced design features a highly efficient rare earth permanent magnet brushless DC motor. This allows the fan to operate even on cloudy days with only 1W of solar power. Improved blades and high-efficiency channels increase solar output by 20% and CFM by over 50% compared to previous models. An integrated MPPT controller tracks maximum output for optimal energy efficiency. High-Performing Air Circulation – This solar attic fan delivers a robust 2200 CFM airflow through a 35W solar panel, actively replacing stale air and promoting circulation in large spaces (up to 1000 sq ft). It is designed for harsh environments such as attics, commercial workshops, storage warehouses, agricultural buildings (barns, coops, silos), and greenhouses. Energy-Efficient Function – With an in-built thermostat, this attic fan with temperature sensorautomatically starts when the temperature rises above 79°F (26°C) and stops when it drops to 75°F (24°C), ensuring year-round optimal comfort. It also operates automatically during the day without consuming household electricity. Long-Lasting and Quiet Design – Featuring a durable, waterproof copper motor and ultra-silent aluminum blades (operating at approx. 50 dB), this fan is built for reliability. The strengthened exhaust screen efficiently blocks insects and small pests from entering spaces such as attics, workshops, or barns. Hassle-Free Service Promise – We offer a one-year service for this fan and provide replacements for any issues. This fan is a fully integrated unit without extra cables or wiring needed. Simply install it in an area with strong, direct sunlight on the roof, and it will start operating automatically.
