Features: Adopt one-drag two-wire material, with strong waterproof performance, allowing you to install it outdoors where you want without worry Large air flow: Designed with high-quality weatherproof motors, the service life exceeds 6 years. The maximum rotational speed uses a rainproof fan, and the hydraulic bearings are more durable. The use of rainproof fans, hydraulic bearings more durable. The service life of solar panels exceeds 10 years. With a super high wind speed of 2200RPM and an air volume of 152.6CFM, it supports a pet dormitory area of over 250 cubic feet. Weatherproof design: The motor portion of the fan (PCB board/wiring/bearings) is coated to prevent short circuits or damage caused by rain. The waterproof grade can reach IPX7, suitable for outdoor use. Safety protection: The dual fan is equipped with a bimetal protective net to prevent small animals from being injured and to protect the normal operation of the fan blades. Suitable for small chicken coops, greenhouses, sheds, pet houses, and window exhaust in hot summer. The 10W solar panel dual fan kit can push out hot air and cool air, effectively reducing indoor temperature and keeping the air fresh. Note: The speed of the fan is greatly affected by sunlight. When the sun shines directly on the solar panel, the rotational speed of the fan can reach 2200 rpm. When the sun is weak, the fan will work slowly or even stop working. The solar fan has no built-in battery and can only work during the day.
