These attractive low profile solar attic fans are ideal for reducing your air-conditioning bills or making your evaporative unit work to its full potential by dramatically lowering the temperature of your roof space cavity. Unlike wind powered turbine ventilators, a solar powered unit works hardest on hot sunny days and shuts off on cooler days.

A typical wind powered turbine ventilator achieves an air flow of around 100 m³/hr. Our units achieves an air flow of 1410 m³/hr and 2175 m³/hr for the 10W and 20W respectively, resulting in multiple air exchanges in your roof cavity every hour.

The units comes with separate universal square flashing section which allows the installer to size up an installation on the roof, while then finishing the flashing modifications safely and conveniently on the ground. This limits time and frustration spent on the roof and results in a safer install procedure. It also comes with a self-adhering lead free 140mm x 1000mm flexible flashing strip for those difficult areas.

EcoOnline has developed this new bi-panel unit to boost venting in late afternoon times. These units have two solar panels connected in parallel using the special connector supplied. For these units we recommend the first solar panel be mounted facing the midday sun with the another panel facing the afternoon sun - creating a much broader venting power peak with unbeatable venting in late afternoon when it gets cooler.
