Any ceiling fan should be at least 2.1 metres from the floor to the blades of the fan. If you have ceilings above 3 metres, you may require an extension rod.
Vento Swish Extension Rod 55cm – Colour Options
These extension rods will fit the Vento Swish ceiling fans. The extension rod replaces the standard rod provided with the fan to give you a larger ceiling to blade drop, making the fan more suitable for a higher than standard ceiling. Note: This rod can be cut to size by the installing electrician.
