*Due to lack of industry standards, CFM is often quoted as the maximum peak output of a bare fan in laboratory conditions. iSolar CFM is representative of operating in typical attic conditions ranging in output from 250 CFM to a maximum of 400 CFM, depending on intensity of the sunlight and duration of direct sunlight on the panel.

Our Product has Been Tested for Safety, Air-Pressure Compliance, Hurricane Wind Endurance and Energy Efficiency by the Following Independent Organizations:


By design, the 19W-MOD iSolar Attic Fan focuses on the Environment and Sustainability

  • The 19W-MOD iSolar Attic Fan is manufactured with cast aluminum, aluminum and recycled plastic, all of which are recyclable at end of life which is estimated to be 20 years or more.
  • Our packaging is produced with recycled paper.
  • Our product is 100% solar powered and therefore uses no electricity.
  • iSolar Attic Fan extends the life of roofing materials (shingles and wooden trusses) by keeping the attic related surfaces dry and free from mold and mildew.
  • The iSolar Attic Fan extends the life of air-conditioners as they will require less usage due to lower temperatures in the home. Lower temperatures will trigger the AC ON switch less frequently.
  • The iSolar Attic Fan was developed to be as simple and environmentally slimmed down as possible to avoid inclusion of unnecessary and bulky additional materials such as batteries, extra solar panels, timers, controls and regulator components.

“iSolar is the ideal partner for us in the area of attic management.”
