Product Features

  • An added lip makes the curb mount design perfect for flat, tiled or unusually steep roofs; fabricate a simple frame from 2x4s to create a solid platform and assist in water runoff
  • 28-watt solar panel captures sunlight from dawn to dusk and efficiently converts it into electric power to keep your attic cool and dry all day long, providing 537 Maximum CFM and year round protection for the structure of your home
  • 12” diameter, one-piece aluminum 5-blade fan is pitched for maximum air flow to keep your living area cooler, extend the life of your air conditioner and save energy and money
  • Compact base footprint means fewer shingles to cut for easier, faster installation
  • Low profile, integrated design for an attractive, unobtrusive addition to your roof without the need for props or pivoting stands used by some manufacturers
  • Rugged, tempered glass solar panel withstands large hail and won’t delaminate so you can be confident in its reliability, functionality and attractive appearance
  • Housing is a molded design of UV-stabilized, color-dyed, rugged ABS plastic that withstands hail and resists fading to remain attractive for years; may also be painted to match your roof color
  • Housing frame features positive stops to “seat” the dome for fast, easy installation
  • Direct-current, variable voltage motor is dynamically balanced for superior performance and silent operation for years of worry-free operation
  • Includes stainless steel fasteners and galvanized steel brackets for durability and corrosion resistance, and aluminum, heavy-gauge screen to keep out insects, animals or birds without impeding airflow
  • Optional thermostat is easy to install and disables the motor when the temperature dips below 50-degrees, to extend motor life; recommended for climates where cold weather condensation isn’t a concern
