Over 80 years of continued design and manufacturing experience has been invested to produce today’s range of ultra-reliable Flettner ventilators.

Our wind powered ventilators are very versatile and suitable for use in a range of applications.

The principle is deceptively simple: mounted on a spindle, the extractor fan is driven by an air scoop which catches the air stream created by the motion of a vehicle or the prevailing breeze. Beneath the spinning air scoop are vanes which expel air, drawing stale air from below. The construction of the unit prevents the entry of rain, dust and downdrafts. Extraction capacity is remarkably effective and can be regulated by adjusting the internal shutter. Wind power means a quiet, totally maintenance-free performance with no electrical connections, no battery drain, no running costs and no distracting motor noise.

The provision of adequate ventilation in vehicles and buildings is often overlooked. Compared to the total cost of equipping a work vehicle or building, the fitting of a Flettner ventilator represents a minimal investment in order to ensure the continued comfort and safety of driver, passengers or occupants.

With their proven performance, innovative product design, engineering excellence and the support of the manufacturer’s lifetime warranty – can you afford not to fit a Flettner Ventilator?
