The Vortice window fan Vario 300/12 really stands out due to its many facets. An outstanding air flow is guaranteed no matter where the fan is installed, be it in windows, walls, panels, normal or angled ceilings - the ball bearing, capsulated motor can handle all positions. A balanced blade wheel in combination with protection against thermal overload give you the opportunity to constantly operate in environments with up to 95% relative humidity and 50°C ambient temperature. An automated electric shutter on the inside of the device prevents cold outdoor air from entering the inside, however it is also possible open the shutter manually to create natural ventilation.

The Vario 300/12 in our Creoven shop is a real multi-purpose device: The reverse feature allows you to switch from supply to exhaust ventilation. You can choose from two models, one with super boosted performance and 1650 m³/h air flow, the other one with 1050 m³/h is even more quiet during operation. Thanks to low noise development and a modern housing made of synthetic material that is resistant to yellowing, this fan is ideal for residential and commercial premises. The device is controlled either with speed controller units or step transformers, control devices and other extras are available in our shop.
