    Attic Roof Hybrid Fan

    Posted by EP on 30th Jan 2023

    This product is a good investment for any home owner. Since will use a solar power during a day and if at night still needed will use the power from the house, will lower your electric bill specially on the summers. Also the DC motors are very reliable and quiet.
    Good choice....

    Very Effective Attic Fan

    Posted by Edward on 21st Dec 2014

    I purchased two of these Green Machines to cool my attic. I like the feature that it's a Hybrid and has in both Solar and Electric. I recommend them.
