The Ventis Auto Whirly is a powerful, intelligent set-and-forget solution—when paired with the Ventis system. It automatically detects when your roof space becomes excessively hot during summer and activates to expel trapped air at an impressive 325 litres per second through your eaves or roof vents.

By reducing ceiling heat buildup, it improves overall home comfort and boosts the efficiency of your existing cooling systems. Whether you’re using passive ventilation or a full mechanical setup, the Auto Whirly is a smart upgrade for better year-round climate control.
