iSWIRL 300

Solar and wind-powered residential roof ventilation

iSWIRL 300 combines a solar-powered internal fan with wind-driven rotary ventilation to extract hot and moist air from domestic roof spaces.

Product information

Solar and wind operation

A solar panel on the top of iSWIRL 300 powers the internal fan in sunlight. The outer vanes rotate when wind is available. The two mechanisms help the ventilator make use of sunny, still conditions as well as breezy conditions, without relying on a mains electricity supply.

Roof-space ventilation

The ventilator extracts air from the cavity above the ceiling. With suitable replacement-air openings, this encourages circulation and helps release accumulated heat and damp air. Performance varies with sunlight, wind, the roof layout and the available inlet path; it should be selected as part of a complete roof ventilation design.

Retrofit options

iSWIRL 300 is intended for domestic applications on metal and tiled roofs. A compatible existing collar may be reused where its diameter, condition and flashing are suitable. The nominated retrofit collar diameter is 306 mm. Check the installed base rather than assuming every nominal 300 mm ventilator has the same connection.

Installation and care

  1. Check the roof type, pitch, flashing and the installation position with the selected base. Keep the solar panel exposed to useful sunlight.
  2. For a retrofit, verify the existing collar diameter, condition and weatherproofing. Replace an unsuitable collar or flashing rather than forcing the head onto it.
  3. Provide the required replacement-air path into the roof space and position units for the roof’s ventilation requirements.
  4. Keep the panel and air openings clear of deposits and obstructions. Inspect the flashing and rotating assembly during roof maintenance.

Frequently asked questions

Does the solar panel charge a battery?

The brochure describes a solar panel that powers the internal fan during sunlight. Wind-driven ventilation operates when wind is available. Battery storage is not listed in the product brochure.

Does it still use wind?

Yes. Wind-driven rotary ventilation works alongside the solar-powered fan when the respective energy source is available.

Can it replace an existing whirlybird?

A compatible 306 mm collar can be suitable, subject to checking the collar, base and flashing condition.

Will one unit suit every home?

No. Quantity and layout depend on roof dimensions, sunlight, wind exposure and replacement-air openings.
