Feature: 1.Efficient Temperature Reduction: The solar panel powered fan effectively expels hot air from indoors, leading to a significant reduction in indoor temperatures. This helps create a more comfortable and cooler environment, especially during hot summer months. 2.Solar-Powered: The solar powered dual fan operates by harnessing solar energy through the solar panel. When sunlight shines on the panel, it powers the fan, allowing it to operate at speeds of up to 3000 rpm. The fan's speed may slow down or stop working when sunlight is insufficient. 3.Flexible Installation with Wire-Free Design: The solar panel can be conveniently placed in a location that receives ample sunlight, while the solar fan can be easily installed and connected without the need for extensive wiring. This wire-free design offers flexibility and simplifies the installation process. 4.Environmentally Friendly and Safe: The solar exhaust fan is a battery-free product, making it an eco-friendly and sustainable choice. Its epoxy resin surface layer provides protection and durability, with an IP65 waterproof rating, ensuring safe and reliable operation. 5.Wide Range of Applications: mini ventilator, 10W 12V, waterproof solar panel, powered fan, greenhouse, chicken coop, shed, dog house Description: This 10W 12V mini ventilator is powered by a waterproof solar panel. It is ideal for use in greenhouses, chicken coops, sheds, and dog houses outdoors. Provides ventilation and helps keep the air fresh.
