Ventlite 300mm - 410mm Rotary Roof Vents

Ventlite domestic ventilators feature a larger throat size compared to the domestic ventilators offered by most other companies. At throat sizes of 300mm, 360mm and 410mm, these models are able to ventilate larger roof areas effectively.

Ventlite constructs these domestic rotary vents using high-quality aluminium. Aluminium construction ensures that these vents are light-weight enough to be easily installed on most roofs. Aluminium is also anti-corrosive, so these vents are perfectly suitable for coastal regions where humidity and sea spray may corrode steel vents.

All three domestic models from Ventlite feature aluminium arms for internal bracing. Dual steel ball bearings offer smooth and noise-free rotation for these whirlybirds. The steel bearings are self-lubricating so they require no maintenance on your part. The bearings are housed in reinforced fibreglass material.

You can install these vents quickly and easily thanks to the variable throat offered with them. The variable throat makes it possible to install these vents on roofs with pitches up to 45 degrees. To ensure an aesthetic finish, the vents feature a large and malleable flashing which effectively covers the ventilator hole in the roof.

Ventlite offers these vents with an optional axial fan blade. You can have the fan incorporated into their design if you want additional air flow from these vents. This is a particularly useful option for sweltering summers where increased air flow can translate into cooler interiors.

All three domestic vents from Ventlite are available in Mill finish and 29 Colorbond options. So you can easily choose a look that goes best with the style and outlook of your roof.
