Small. Powerful. Versatile. Effective.

  • 30 watt solar panel, compact high output fans that fit inside the soffit vents, and tilt & rotate solar panel Flex Mount combine to provide fresh air supply to the attic, reducing attic heat & humidity.
  • No cutting or drilling holes in the roof. No leaks. No need to access the roof. No need to go in the attic to install the fans. No roofing work or repairs.
  • Proven hurricane tough.
  • Ventilates up to 1000 square feet of typical, non-partitioned attic with fresh air supply. 7-10 fresh air changes per hour above the ceiling, where it counts.  Pressure of 0.37” H2O puts fresh air deep into the attic space. 
  • Fans can be installed through soffit vents between 16” or 24”o.c. trusses, without going in the attic.
  • Can be used with continuous vents with minor modifications.
  • Flex Mount attaches to solid structure (wall, chimney, truss ends, solid fascia, etc), not to the roof deck.  Allows optimum sunlight capture from any side side of most buildings, and allows the solar panel to be located out of view.
  • Water & dust proof to IP55 or greater. 
  • Simple, automatic on-off. 
  • Easy fan and solar panel adjustments. 
  • Quiet - 45 dBA   
  • Pricing competitive with conventional solar attic fans without the added installation cost and risks of roof mounted solar attic fans.
