    Solar Options For Your Attic Ventilation

    Solar Powered Attic Ventilation - Pittsburgh Today - Live KDKA TV

  • Effective attic ventilation requires air to exit at or near the peak of the roof and replacement air to be drawn in under the eaves of the house, via soffit venting. The Home Ventilating Institute (HVI) recommends that powered attic ventilators provide at least 10 air changes per hour to equalize attic temperature.

    Answer: 
    Thank you for your question on the model 345SOWW solar operated attic ventilator. You would want to mount the 345SOWW near the peak of the roof. If you only have one make up air vent, you want to be at the opposite end of the house. If you have multiple make up air vents, you want to be somewhere in the middle of them. Please contact the Technical Service Department at 800-637-1453 for further assistance.

The 345SOWW is designed for attics that are a maximum of 3200 cubic feet and has a minimum of 2 square feet of inlet area. If your attic area meets these specifications, it should work fine for you.

    Where can I get new brushes for the motor?

    This Model fan has been on my roof for a couple of years. It had stopped working, so I did some tests. The solar panel was still putting out voltage, but the motor was not working. I opened up the motor and the brushes had worn down to nothing. I need new brushes, but I cannot find where to purchase them. I'd rather spend a couple of dollars on a new set of brushes, then $100 for a new motor.

    When I can't find prices I go to another site that is more informative. Not being able to quickly ascertain the price of an item is maddening when you are planning a big project. I don't have time for games!

    Answer: 
    Thank you for your question on product pricing. Since we only sell through distributors, we do not list finish goods pricing on our web site. You can contact the Customer Service Department at 800-558-1711 to get suggested list pricing, but you would probably be better off using the “Dealer Locator” link at the top of our web site page to find distributors in your area to get current pricing. Many of the distributors do have web sites and list their prices.
