OmniPV Solar Attic Exhaust Fan Pro 2nd Generation,2850 CFM, 40-104℉ Thermostat, 50W Solar Panel, 24W Adapter, Cool up to 4000 sq. ft., Low Noise, Ideal for Home, Greenhouse, Garage, RV, Shed etc.
 
Larger ventilation: 50W solar panels with up to 2850CFM ventilation allow a 4000 square foot room to cool down quickly, remove humid air, and keep the room comfortable and dry
Higher efficiency: The new upgraded design adopts a more efficient rare earth permanent magnet brushless DC motor, and the fan can run even on cloudy days when the solar panel's power generation power is only 1W. The high-efficiency fan blade shape designed by professional fluid design software and the high-efficiency runner design simulated by professional software increase the solar power by 20% and the CFM by more than 50% compared with the previous generation. It provides continuous angle adjustment of -45~+45°horizontally and 0~60° vertically, so that the maximum power generation efficiency can be obtained no matter where it is installed
More Features: Temperature control provides a choice of control range from 50-104°F, as well as turning off the temperature control function to start the fan at the right temperature for barn, greenhouse applications, or keep the fan running when dehumidification is required. Equipped with a 12V2A AC adapter, plug in the adapter, the fan can run at night or on rainy days, and exhaust the humidity in the room. Provides an external wall switch to turn the fan on or off, whether powered by solar or AC adapters.
Longer life: All structural components are made of aluminum alloy, which will never rust, even if the surface protective coating is accidentally damaged during installation, it will not leave unsightly rust on the roof due to rust. The long-life rare earth permanent magnet brushless DC motor will not shorten the life of the motor due to brush wear
More reliable installation: The mounting plate is made of aluminum alloy with a thickness of 1mm, which can be arbitrarily bent into the shape of the mounting plate and the roof tile, especially the wavy or square metal roof, the gap between the mounting plate and the roof is very small, and the waterproof glue is more guaranteed. Equipped with 8 M8*50MM screws to fix the mounting plate with the roof, it is also equipped with two 6.5ft long stainless steel wire ropes, which are used to pass through the fan body to fix the wire ropes with the beams or columns of the roof, which greatly increases the ability of the fan to prevent storms.
